[Q] Bluetooth AD2P Sound Quality - Moto X Q&A

Is anyone else aware of the TERRIBLE streaming quality via Bluetooth? the mids get crushed and sound terrible when I connect my X to my car. Did some research and found a fix for the GNex here:
http://forum.xda-developers.com/showthread.php?t=2184333
I tried to apply it to the X but it turns out there's no bluetooth-default.so in the system/lib/hw folder ... only a2dp.default.so
I replace just a2dp.default.so with the 'fixed' ones from that thread and then my phone wouldn't hold a connection to the car (Gmusic kept telling me "cannot play requested stream") and when I toggle off/disconnect from bluetooth my phone would reboot.
anyone got ideas for a fix?
there is a directory called bluez-plugin and inside that there's an audio.so and a bluetooth-health.so but I dare not mess with them hehe.

I haven't noticed poor quality streaming at all... I have used it a lot.

The Moto X doesn't use the AOSP bluedroid stack, they stuck with Blue-Z stack so it doesn't have the same problems, and you can't apply the same fix (as you discovered).
My experience has been 100% positive with Bluetooth audio on this device, it sounds just as good as the fixed AOSP bluedroid stack does to my ears on all my BT receivers. I don't know for certain but it's pretty likely that the Blue-Z stack Motorola used is newer than the last one we saw in AOSP (Android 4.1) and there is probably an incompatibilty with your car if it really sounds that bad.
Before you guys jump all over me and call me an idiot ... I happen to be the guy that came up with that particular fix for the AOSP bluedroid stack in the first place :silly: (http://code.google.com/p/android/issues/detail?id=39632#c151) <--- woot! I'm this guy! LOL, whatever, I know. What the fix essentially did was set the bitpool (like a buffer) to the recommended size for high quality audio, but modern Blue-Z implementations didn't suffer from the same problem. It was introduced with AOSP Android 4.2 and persists in AOSP Android 4.3.
Do you have any other A2DP receivers to test against at your disposal? I've used my VZW Moto X against a Rocketfish Receiver (http://www.rocketfishproducts.com/products/home-theater/RF-BTR212.html), an HDMX Jam (http://www.hmdxaudio.com/jam-classic-wireless-bluetooth-speaker.html) and most recently a Bose Soundlink Mini (http://www.bose.com/controller?url=...s/bluetooth_speakers/soundlink_mini/index.jsp) -- playing as I write this post -- it honestly sounds just as good as my fixed Fascinate and my fixed Galaxy Nexus did, perhaps even slightly better!
Moto X A2DP = djp952 certified! :victory:

I have the same issue with poor sound quality when I stream music to my 2013 Subaru Legacy stereo. The problem seems to be that the sound is overly compressed and when a lot is going on it becomes especially noticeable. Part of the issue revolves around devices that don't support the newer APT-X codec, if the device supports that codec the sound is said to be fine however any device that uses straight A2DP will experience this issue.

I have had the same experience as you. I have tried my Moto X with about 10 different bluetooth receivers. I have had nothing but excellent sound quality.

I'm experiencing the same crappy BT audio I was with my galaxy nexus prior to your fix (thanks a lot BTW) on my moto x with the same BT receiver in my car. I've got a couple others I will try and report back later.

Moto x doesn't sound good on any BT device I have but none of them support apt-x which the moto x does? I know the rocketfish you mentioned has apt-x but not sure about the other 2. If they do maybe that's the difference in sound quality?

I'm not sure either It's a good bet the Bose one does since its brand new. Seems like a pretty good theory!
I think I still have a really really old Scosche receiver kicking around somewhere I can try for you guys and compare it with an AOSP bluedroid-based phone.

http://www.csr.com/gogroove-bluesync-portable-bluetooth-speaker
Forgot to test on that which does have apt-x though I don't think it specifies in the manufacture or amazon site but that's the actual apt-x website. Can confirm that it definitely sounds better than my other devices.

Some Test Info if it helps
I have the same audio quality issue with my VZW Moto X, constant crackling noises, but I only experience it with one bluetooth receiver (of the ones I have available to test). Unfortunately, it's the only one I have built into my primary vehicle, so it's extremely frustrating. I don't have any data that indicates what these products support in terms of codecs, but here is some info if it is of any use in diagnosing the problem:
Pioneer DEH-X9500BHS - Works Great for BT-Audio and Pandora Mode
Satechi Soundfly View - Works Great
iSimple Connect ISHD651 installed in a 2008 Honda Accord - Worked Great with my Droid Inc 2, but horrible crackling with my Moto X.

I don't see any indication that states that deck supports apt-x. I read on the android bug report page that one user running 4.4 claims they've finally fixed this issue so I guess we wait for 4.4 now.

The deck does NOT have to support apt-x in order to sound good. The moto x is the best sounding bluetooth device I have ever connected to my deck, and my deck for sure doesn't have apt-x. I am so up tight about sound quality that i've always used a cable to connect my devices. The moto x is the first device I have used where I no longer need the cable and have thrown it in my closet somewhere.

My Bose Infiniti head unit sounds amazing streaming Bluetooth from my wife's iphone4s and a load of rubbish while streaming from my motoX.
I'm very close to just saying screw it, giving in, and buying an iPhone.

Bluetooth audio router ?

I can't seem to find a program which will route ALL audio to my mono bt earpiece. If there is such an app pls pst. If not, I'd like to help in the dev of such an app. Basicly, whenever the phone sees any audio bt device it will start routing all audio to that device. And it should have a built in audio mixer to control the different programs' volume levels separately.
Let me know what you think
Thanks.

As a bike commuter this feature would be great. I typically listen to streams and podcasts where fidelity is not priority one. I use a cheap pair of corded headphones where I chop one ear bud off so that I can keep my left ear, traffic side, open. It would be sweet to have the ability to make/take calls on my commute and listen to audio as well. I know that there are BT earpieces that are a2dp, but should I really have to drop another 40 clams to get one, hells no this is android we get what we want right? That said I would develop a prog to do this but it will take me 6 mos as I have no background. So, to kind devs, myself and several others that I have seen scouring for this sol'n would gladly help test and pay for this functionality.
I have been looking also. Have not found anything to even mention. I used to have it on my old MinMo phone, but that's the ONLY damn thing I miss about it. Anyone have a recomendation.
theres a bunch of cheap A2DP headsets at dealextreme.com just do a search for a2dp
But I do mean cheap dont expect miracles for sound quality or battery life . . . but did I mention cheap?
We're not trying to solve our problems by purchasing MORE hardware, we're trying to make do with what we have and find new uses for old stuff. We want to send ALL the audio from the device to a mono NON a2dp earpiece. It can't honestly be that hard, Please devs. And don't forget your donate buttons.

This is not working for me, and I have 3.0. Doubt that 4.0 is working on the G1.
Hello!
Sorry to up this "old" topic, but I'm a biker too and i have a scala rider Q2 bluetooth device. This device does not support the bluetooth A2AP x-(
The phone calls trough bluetooth is ok but no music or GPS....
I found a solution : Bluetooth Audio Widget (i could not post the link but you can find it on the android market)
This Widget/application route all the sounds from your device to the bluethoot headphones!
@++
I have been using "Super BT Mono Pro" on my T-Mobile G2. It is working better than a few of the other apps that I have tried. It is also available on the Market.
http://www.androidzoom.com/android_developer/sinwidget_itzo.html
How do you like that Q2? Does it work well on FM, or is its radio coverage spotty like the other units? I still think they have awesome audio when you are talking to someone. I gave up the Scala Rider FM for a Parrot SK4000.

Htc One Bluetooth issues

Hello Everyone I am here to find some answers (hopefully)...
So I got the HTC One Coming from the Iphone 5. I've had numerous Android devices before, and apple products. I just recently also purchased a subaru wrx, it has bluetooth radio. When I had my iphone 5, i synced perfectly with the radio, hands free worked Awesome. When i got into the car my spotify or pandora would immediately start playing..
Now i get my htc one, and i pair my phone with the car, but my hands free audio sounds terrible, i can barely understand what the other person is saying. On top of that i have to manually connect the phone to bluetooth everytime i turn on my car, its very annoying. I have tried many different roms, and kernels, and i even went back to stock but i can't seem what the problem is. I am about to change the radio in the car thinking its not very user friendly with android devices.
If anyone can point me in the right direction that would be awesome. I am pulling my hairs, i love the htc one, but i miss my handsfree bluetooth functionality. I have tried searching the forums, but i haven't found any answers that worked.
I am having the same issue with having to manually confirm the Bluetooth connection in my car. Mines on a Toyota 86 with the GPS in dash, I believe it's made by eclipse who supply Subaru?

I have to manually connect each time to my bluetooth nakamichi speaker.
I too am having same issues. I also have a 2011 WRX with original radio. With my prior phone (GS2) I connected without problem and automatically every time I started the car. I have to manually connect the HTC one every time. Many others seem to not have this problem with other vehicles, so I'm starting to think it's the Subaru radio not playing nice with the phone. Please post if you find a solution.

I installed an app called Bluetooth file transfer that fixed the issue somehow.

I had similar problems in my car with an alpine radio, but with my galaxy s3.
In fact the thing is that when you register a phone on your radio (in my case) the radio just looks for the first one defined and registered to autoconnect.
Now, if in your radio you clear registered devices list, and try to register your htc, i am pretty convinced that it will autoconnect all the time.
Hope it helps,
Regards,
Nicolas.
My HTCone synched immediately with the OEM bluetooth in my 2011 Kia Forte. No problema, in fact, it is a much better connection (clarity) than with the old EVO 4g, which initially required a bit of fiddling to make work. Hands free phone call system on the KIA works very well too. FWIW.

Thanks for that. I sorted out how to BTconnect my HTCone<--> Macbook, but could only do so, one file at a time. The app you mentioned works great (!) and allows me to push multiple files at ne time. Reviews say it is also a great file manager, that I have yet to determine but if so, an added bonus.
I am also having a problem with the HTC One bluetooth in my car. The phone connects to the car’s bluetooth system, pairs properly, although very slow, it uploads the phone book and call history. The problem is the call quality. The people I am calling complain about the sound, they feel the volume is too high and this distorts the sound, as well as there is too much noise added to the voice, or something like that. As soon as I switch to the phone speaker the sound that they hear gets better. This makes me think the bluetooth on this phone sucks. One person suggested the interaction between the noise canceling and main microphone is mixed up, but if I am using my car's sound system it should not use the phone's microphones anyway, or maybe it does? I guess what I am trying to say is that when I am using the car's stereo it should use only the car's microphones and speakers , but sound like the phone noise canceling microphone is still active.
If anybody has ideas for fixes, or suggestion for further tests, I will do it.
P.S. I didn't have any problems with my car's bluetooth with my iPhone 4 or Nexus 4.
Same for me. Sometimes the problem disappears. I assume the problem comes from the BTstack. In fact, the one is the only Android phone I know that use a different BT stack than blueZ. This stack is HTC one. It allows us having avrcp 1.3 (The name of the song displayed on our car audio). I hope the HTC one Google edition use blueZ stack. I will try a Rom based ion that. If the problem disappears, it will confirm the problem come from HTC stack.

BT problem
Hi,
I'm also having a problem with my BT while paired to the BT in my awesome Volkswagen sirocco.
I don't see any contact or missed calls or recent calls. The log is empty.
Any help will be much appreciated.

I am having the same issue...I had the Motorola Atrix 4g and it paired immediately with my Pioneer deck. That phone always reconnected and like you mentioned, pulled up Pandora etc. Now I have the HTC One, and it paired and connected but it refuses to play audio. Handsfree works (kinda sloppily, also like you mentioned), but the Media Audio portion doesn't work even though the phone reports that it is connected. My stereo says no device detected when I switch to BT Audio. I hope you find a resolution to this issue, I have searched everywhere and of course I saved the best for last and decided to finally check here @ XDA.
I posted earlier in the thread that I was having difficulties pairing my One with my Subaru WRX factory radio. I could not get it to automatically connect with the phone each time I started the car. I could manually get it to connect but that was a pain every time I got in the car. I was able to solve my issue by deleting every other pairing the radio had with other prior phones. I deleted any pairing my One had previously and then paired it with the car radio before any other device. It now connects regularly every time I start the car, and both audio and phone functions work perfectly. I would recommend anyone having blue-tooth issues to try the same. The Subaru radio also had a weird menu system that was different whether I was pairing the phone by using voice commands or trying to do it with physical buttons on the radio. Very confusing but going through the hands free voice command menu seemed to pair both audio and phone functions, where I could only pair audio functions when using the physical buttons on the radio. Seemed like two different systems.
Been having crappy noise issues with my 09 Acura TSX. I emailed HTC regarding this problem but, of course, their response was to 'check with the car manufacturer'. Will try that method and see how it goes.
My problem is a bit different. My htc One connects flawlessly with my JVC unit that too automatically. But it keeps disconnecting and reconnecting. And that is a major issue. The phone also gets insanely hot in this process and today the OS crashed two times and i had to do a Hard Reset.
I am coming from an iPhone 5 on which bluetooth streaming was flawless.
Anyway to stop the auto-disconnect and re-connect going on.
My Bluetooth is mess up.
It can pair up, but the Address Book is not showing up on the car screen menu now. I don't know what happened. When I play music on my phone to the Bluetooth in the car, it is silence.
Does anyone know what is going on?
HTC One Bluetooth Problem in BMW
I am having the same problem.
My HTC One connects, I can make calls from the phone and the calls are clear, but I cannot see my contacts.
I have emailed HTC and they say it is the car (BMW 5 series). I have checked with BMW and there isn't an update for my car available. I am therefore, using the latest software. I previously used the HTC sensation which worked fine in the same car.
I am wondering if one could install an older version of the Bluetooth and A2DP software as the those on the HTC One do not work in my car and I cannot see BMW developing any updates and if they did, the cost could be as much as the phone.
Would appreciate any help

I can now see my contacts after more than a month!
I did many things, some of which I do not believe had anything to do with the process required.So I will stick with the main points and if this does not work I will include all that I can remember.
I unpaired all phones in the car (including the HTC One)
Pair the HTC One
Look out for the message BMW wants......................... contacts
Select yes
Wait for the contacts to load, this took a couple of minutes at least.

Been trying to find out for the longest time the definite set of codecs that the One supports over bluetooth. Besides SBC and AptX, does it also support MP3 and AAC??
The reason I'm asking is that I'm coming from a (company supplied) iphone and have been generally very happy with the bluetooth audio quality to my car's audio system (Audi) and Bose Soundlink Mini speaker. I know for sure the iphone supports AAC and due to the quality suspect it is used in both cases.
The Bose at least does *not* support AptX, however getting a definite codec list for the Bose is also impossible. I only managed to find buried in the offfical bluetooth certification pages that it is a BT2.1 device.
Why do all these manufacturer's hide this documentation?
Very disappointed to find out that the Bose Soundlink Mini negotiates a link with the HTC One using SBC...
These are both premium devices for which top dollars are paid, and they still shovel this **** on me.
I'm not sure on where to place the blame here, HTC for only(???) supporting AptX next to SBC, or Bose for only supporting SBC(???)
As mentioned, both are not transparent in their devices capabilities - isn't there an app to find out these things?
Beats is at least more clear: "Bluetooth 2.1 audio and supports SBC, aptX, AAC Codecs for high quality streaming"

[Q] A2DP Audio Crackle with iSimple Connect (ISHD651)

I just got a new VZW Moto X, (4.2.2) and while trying to stream bluetooth audio to my car stereo via an isimple connect kit (ISHD651), I get a very annoying static/crackling sound, which makes listening unusable. My old phone (HTC Droid Incredible 2) (2.3.7) worked great, with no issue whatsoever. However, the Moto X does work fine with my wife's car stereo (Pioneer DEH-X9500BHS). This seemed very strange, so I did a bit of investigating with a bunch of our devices. The Droid Inc2 (2.3.7), Nexus 7 (4.3), and Wikipad 7 (4.1.1), all worked fine. My Acer A500 (4.0.3?) and the Moto X both exhibited this crackling with my iSimple Connect car kit, but worked fine when streaming to other devices.
Has anyone else seen this problem? Is anyone smarter on bluetooth a2dp that could explain what might be happening here? Are there any other ideas of what I can try?
This is extremely frustrating, as I bought and installed the iSimple kit specifically for this purpose, so I could stream audio and control play/skip from my car stereo, and it was working great with my Incredible 2, but that phone was showing its age.
I've seen some info about other 4.2.x devices having bluetooth audio quality issues, but I wasn't sure if it was the same problem or not.
Any ideas?

I just changed from a 2.3 device to a droid mini running 4.4. I have the same problem. I've contacted Isimple to open a ticket and hopefully see if they will release a patch to flash the isimple connect gateway with. The droid mini works without issue with a bluetooth speaker that I connect to - but does not work properly in the car.
The symptoms are slowed audio, and crackling.

I've contacted Isimple to open a ticket and hopefully see if they will release a patch to flash the isimple connect gateway with. The droid mini works without issue with a bluetooth speaker that I connect to - but does not work properly in the car.
The symptoms are slowed audio, and crackling.

I've tried pursuing the problem from both the PAC(ISimple) and Motorola ends. Never got anywhere. 4.4.2 on my Moto X doesn't fix the problem either. I've pretty much just given up on it working. I guess I'm just stuck with using a AUX cable for music. Voice calling works fine, but bluetooth would be much more convenient

I have a ticket in with PAC. I told them the whole issue, mentioned this thread, and even offered to beta test a patch.
I suggest you do the same. Call them again, open a ticket. They acted like no one had called before about it.Speak to them on the phone.
I'm using aux for now, but surely this can be fixed. I don't think 4.4.2 would have fixed it... 4.4.3? maybe... isimple isn't the only device that got broken from 4.4 though.

Unfortunately, I had some issues with technical support this past friday. I have gotten no indication they have even tested the device, nor that they even want to. They have tested ios7 though, and released a document on how to deal with some connectivity issues with ios7 and the isimple.
PAC is blaming google, and says to contact motorola, but we all know that this is futile.
Looks like I might be ditching this thing soon. I am unimpressed with their willingness to even understand the problem, let alone try and fix it. If anyone else has 4.4 and an isimple connect, I urge you to call in and voice any problems you are having.
Just Talked with PAC
So I just got off the phone with PAC as I was experiencing the exact same issues on my 2007 Classic Chev 2500HD. I spoke with tech support and they told me they were unaware of any such issue. I mentioned this forum, but still said that this is the first they herd of it. I do not have the Moto X, but I am having the same problems with my Note 3 Running 5.1.1 CM. If anyone does find a solution this would be truly helpful.

[Q] Bluetooth Issues

Been having bluetooth audio stuttering issues with the Moto X when playing music/podcasts. Only seems to happen in my car with the Chevy MyLink system (Blackberry QNX-based). Works fine with a regular set of bluetooth headphones.
I've tried:
Disabling Wifi
Rebooting Directly Before Connecting to Bluetooth
Re-pairing the device
Turning off NFC
Un-pairing all other bluetooth devices
Turning on the developer option to leave the screen on when plugged in, to force the phone to not sleep
Moving the phone to different places in the car (assuming it was a reception issue)
Disabling the phone profile in bluetooth, leaving only the media profile
Different music players
Playing music from local storage rather than streaming it
None of it seems to help. The only real difference I can see is that the car bluetooth stereo supports AVRCP 1.3 (Track information, song/album title) and the other bluetooth streaming devices I've tested don't.
Does the Moto X just have a buggy bluetooth stack? (this worked fine on my old Note 3) Anyone else have this issue (and possible have a fix)?
I just started using my phone in my car to stream music today, using a CoolStream Bluetooth adapter and noticed the same thing. I have two CoolStream devices, so I was going to do some testing before posting anything (I used the other in my office today without issue). I just received a replacement Moto X (for another reason) today, so I will try it out tomorrow.

Funnily even I have Bluetooth issues.. I own a pair of bluebuds x and after pairing the device the audio was still playing through phone. I have to disconnect Bluetooth and restart bluebuds x and immediately start playing music after connection is established. if I wait for 2 mins again same problem.
From the motorola forums, there is a suspicion that this is related to the charger that is being used. Can you confirm if this happens if you are using bluetooth music on battery?

This happens even when the phone is on battery.
That being said, it does seem worse when I'm using my Belkin 2.1 amp car charger.
Hmm, definitely starting to sound like a bluetooth software problem, hoping this gets some visibility @ Moto.
Works well for me
No issues at all for me in my 2014 Hyundai Tucson.
Huge problems mine connects then disconnects every 30 seconds have called Motorola 3 times going to call again ask for exchange or refund.

I was having the stuttering problem when using Bluetooth in my car (Subaru Imprezza). I use the PowerAMP audio player. Going into headset/bluetooth settings (in PowerAMP) and enabling the "High Priority" setting fixed this.
On my BT headset, it's always been fine. (i use the Motorola S11-HD)
I got in touch with Motorola support. They are replacing the phone. We'll see if the new one does the same thing.

I am on my second phone, it is better than the first, but the problem still exists.
This sounds like a major problem - I have a Sony Smartwatch 3 and it keeps dropping. I haven't tried anything else yet but this is already not looking good. Anyone with any answers running Lollipop?
same if not worse
I went from a moto x 2013 to a 2014 and uograded to lolipop. The stuttering is still on lolipop and i have othwr issues as well. When I try to play a vox it doesnt pause audio and is silent. It also fails to auto connect about 50% of the time. And wven when it does the audio is muted and i have to disconnect and re connect. Using an Alpine ute-42BT
I've been using my Moto X 2014 with a 2011 BMW and I have no issues with stuttering. The version of the car's Bluetooth stack supports AVRCP 1.4. I had some quirks with it and my previous LG G3 (time display was off, and previous/next controls from car didn't work properly). With the Moto X, everything works well and all information is displayed properly.
Does anyone know what version of AVRCP the Moto X has when running Lollipop? It seems like stock Lollipop is still stuck on 1.3 (I can't get a clear answer), but with the time being reported properly, I suspect 1.4 is being used on my Moto X.
I also have issues w Bluetooth. Stutters randomly w my Subaru Impreza, as well as my 2 UE Boom Speakers. Using Google Play Music All Access.
In addition, the Jawbone UP24 wouldn't sync w my phone. Had to restart the phone to push a sync through.
My phone was working fine until today. I was able to pause, play, and skip with my bluetooth receiver, but the audio was still coming out of my phone. This is terribly frustrating. I can't believe such a large issue has been going on for months with no announcement from Motorola.
My pure edition on lollipop stutters when the active display goes off on Bluetooth. Only send to happen then
I've notice using Bluetooth headphones none have the range they are suppose to. I've used Power beats 2 wireless, JBL Synchro's wireless, and Moto Hint. The range and Bluetooth auto seem to lack badly. Using a Bluetooth to aux adapter in my work van I've noticed it skipping as well. Hope this gets fixed its apparent that its a issue with the Moto X Bluetooth.
my bluetooth audio has become worthless. so much stuttering, calls sound like they are under water, moto assist voice in the car is so quiet
i can't stand it.

Audio quality drop on bluetooth

Hi everyone
Little bit lost on this and not sure if it's just me but hoping someone can help or point me somewhere. I have a s10+ UK edition. And a Samsung galaxy watch.
When I connect the phone to the car the audio is low quality and hisses a lot. When I put the watch into plane mode. Cutting it off from the phone. All is normal.
Have never seen this happen before. Any ideas?
Thanks
So you have bluetooth connected to the watch and car at the same time?
If so, my guess would be a setting in the watch for the volume of music. Or in the phone, go to settings / bluetooth / advanced / dual audio. Select it and play with the settings to setup what to do when two bluetooth audio devices are connected

Had the same problem with my cheap external bluetooth to FM adapter.
Turn on Developer Options and adjust the bluetooth profile while connected to your car audio.
Having Dolby Audio set to auto might also have an impact.
Thanks for the advice but no luck so far.
The settings under developers let me change when nothing is connected but they revert back to sbc soon as I leave the menu. And they are locked out when connected.
Also dual audio does nothing.
It only has the issue when the watch is connected.
As if its taking the bandwidth.
@ninjatiger26
@theanykey asked you to change the AVRCP version.
You can only change the audio codec from the default one (SBC) to something like aptX if your receiver supports it. And yes, you can not change the codec on the fly while playing.

Apologies for the delay, has been a mad few days!
Sadly changing the AVRCP didnt help on all versions.
It seems there maybe a weird one however on the codec. It reverts to SBC which from a bit of muddled googling is all my receiver supports. from non iPhone devices. However, it takes AAC if its a iphone.
Seems odd to me however they would limit it. Like i said this is from googling so maybe incorrect.
the stranger part is however i paired up a Oneplus 6 and the watch all was fine on SBC codec. its just watch and the s10+ it has an issue.
Admit very lost on this one.
I'm having the exact same issue. I've got an S10 Plus and a Galaxy Watch Active (both in the brazilian versions), and there is a noticeable crackling and loss of quality when I play music on my car stereo while the phone is connected both to the car and the watch. If I put the watch in airplane mode, the issue is gone.
Also, it only seems to happen with my car. I've tried to replicate the issue with my Sony WH-1000XM3 headphones and an Anker bluetooth speaker, but with those devices there is no noticeable loss of audio quality.
I've tried resetting bluetooth setting, messing with the codecs in developer options and pairing both devices again multiple times.
Anyone got any ideas?

See if the problem persists when you only share your Bluetooth audio to your vehicle and not calls, contacts, or messages.

Why not Google it?maybe you will get a solution for this problem.
Same issue here on my s10+. When playing any audio in my car via BT i hear the distortion/hissing noise especially when the song has a higher treble frequency.
I have just about tried all fixes i could find on Google, and no luck.
When connecting to my ear buds (Jabra Elite 65t) it disappears and checked in developer mode that it supports to AAC for BT Codecs.
But when connecting to the car it reverts to SBC.
The issue clearly lies on Samsungs side, as my brother has a Huawei p30 Pro, also has bluetooth 5 and plays amazingly well in all aspects (Bass-Mids-Treble).
I know I'm posting this almost a year later, but i am desperately looking for a fix.
SN. I have recently updated my phone to Android 10, despite all the complaints to Samsung from many users... Sadly this issue has not beeing fixed on my side.
Does any of you still have the same issue?
I have the same issue with S9(android 10 ui2)
- no dou audio diable option
- bluetooth conected only to my earphones, with no car.
I’ve been a Samsung phone user since the S5 and this issue persists across all their phones since at least that one. The only real solution is to avoid the SBC codec or turn off your watch while listening to music. It will never be patched as it’s been going on for over 6 years. In the early days Galaxy phones only really used SBC so you couldn’t avoid it.
APT-X and AAC are your best options. Good luck finding those on a car system. You can easily find headphones that support them.
