I am finding that the Bluetooth driver/support is better on my Focus S than my original Focus.
The original Focus would always play Youtube and Zune video through the analog out even when Bluetooth was connected.
The Focus S sends audio for everything to the currently selected device, be it analog or stereo Bluetooth.
Also, audio via Bluetooth seems much louder and of better quality.

Hi Folks!
Recently got a bluetooth FM transmitter so i can go hands free in the car and use phones music player too
However the audio is very heavily compressed when using A2DP - no bass and the top end frequencies turn to mush - ie not good enough to use
Checked all eq settings and different FM frequencies, no difference
plugged the analogue audio cable direct from the phone to the bluetooth FM transmitter and immediately got perfect sound again
I dont see many poeple talking about this on this forum or many answers but the closest seems to be windows phones can access and modify registry settings to check and increase the bitrate
My current thinking is the bitrate (or bitpool) over bluetooth A2DP is set too low, or when the phone and FM transmitter pair the phone selects a bitrate that's too low for quality audio (but ok for calls)
My question is does anyone know how modify the bitpool settings on the Galaxy S please?
I am going to get a custom ROM and will very happy when the phone is really mine so if that's what it takes I'm up for it
Many many thanks!

Samsung Galaxy S
2.1.1 Eclair on 3 mobile network in the UK
Nexus Drive Transmit Pro (Bluetooth FM transmitter music and hands free car kit)
I have the Galaxy S on 3 UK since August. I use the bluetooth to transmit sound to my Samsung surround sound system (as I don't own a stereo). I don't notice significant quality issues doing this. Are you sure both your devices are supporting A2DP. Not all A2DP devices talking nicely with each other, so you may be failing back to the normal Bluetooth frequencies which are more focus of the vocal range. I'm looking a car stereo's right now that support A2DP so I can stream my audio from my phone straight to my stereo, my phone is becoming the centre of my entertainment!!
I'm running Doc's ROM on my phone, can't recommend moving to his Froyo ROM's and an enhanced kernel enough, my phone is working so much better with his ROM, but there are lots out there to choose from.
I am using A2DP in my car too and I find the sound quality being very good.
The thing is, the default Android audio player (Music Player) is pretty poor and often it lags for me.
Since I moved to MiuiMusic (Search here) all those lags are gone and it works perfectly and smoothly in my car.
Now, as pointed already to you, all BT devices do not communicate flawlessly between each other sometimes...
works great for me, streaming from the SGS to the car CZ 509 deck
i don't even carry CDs in my car anymore
even the lovely sub base sound comes through clearly.
nothing better like a Sonic Massage meanwhile you are driving
I wanted to create a new thread on this, but then I've seen this one. Is there no one with a solution except flashing cyanogen?
It could be a setting on your bluetooth receiver.
For example, I've got a pair of Sony DR-BT21G bt stereo headphones. When you hold a special button combination, it switches it from "high quality" to "any quality", and will just select whatever bitrate it thinks is best, usually, something that sounds about half as good.
Try looking in your manual for troubleshooting and see if there are any settings that you can change on the receiver itself?

Hmm, i using Sony MW600 BT headphones. I've checked the manual, but there's nothing about quality :/
But i dont think that's the problem anyway, as i tried Cyanogenmod and it got perfect quality then. But otherwise cyanogen is quite useless for me on my Galaxy S, its just too buggy. There must be someone who can change the bitpool quality on the stock gingerbread to the highest possible...
Exact same issue for me (as described by DJ LIBRE), I have a Belkin Wireless Bluetooth Music Receiver and the sound quality is horid... it's got nothing on AirPlay which I think is still kind of average quality!
I also wonder if there is a highbitrate setting that can be adjusted?
Running CyanogenMod Nightly #130 on SGS.
After getting used to listening to 24/96 FLAC's with the Voodoo Sound mod enabled with a custom built headphone amp and semi decent can's all I can say is BT Audio is a waste of time!
Has anyone noticed whether the music player was set to 5.1 surround mode? Had a similar issue where turning off the 5.1 fixed the sound streaming...
This doesn't seem to work right off the bat at least, but I was hoping it was possible. I would like to record video with my HTC but use my bluetooth headset for the audio rather than the phone's microphone. Is this possible with video recording software, stock or otherwise?
Hello everyone!
So last weekend I finally received this: LINK (EBAY)
I am totally new at Android Auto, though I have had several Andrioid Phones, as well as an Android tablet. Now I have an iPhone SE - so yes, I turned to the dark side. Not important here and now.
My question is - When I had both phone and tablet with android, I remember the many many possibilities I had with rooting etc. What do I have with my Radio? Can I root it? Can it be even better?
The only negative thing I have to say, is that the sound quality via bluetooth is quite poor - especially in the higher notes. The bass however, is still awesome on bluetooth. The sound quality is only bad on bluetooth - which tells me there is something wrong with the bluetooth hardware og the bluetooth software. Very sad to find out - I listen to bluetooth music 90% of the time. That issue let me to thinking: Is there a way to fix it? Maybe a root or something?
Also - are there some must-have-apps I should know about?
Looking forward to hear from you.
Thanks.
I have noticed the same, however it is not related to Bluetooth, the BT quality is fine, the sound quality problem begins when Android Auto is activated. Try using Spotify with the standard BT connectivity. Then test the same song with the USB cable connected and using AA. The sound quality is fully degraded when using AA compared to the BT quality. I Use Viper4Android and the drop in quality is even bigger since Viper4Android doesn't catch the sound stream.
Any idea out there?
By the way, I'd rename the subject of this thread since the sound quality problem is not related to Bluetooth but with Android Auto.
Same, don't think there's a way around it.

Second comment on that article, has to do with digital vs analog and our built in equalizer. You'd think digital would sound better

BT is also a digital stream and sound is excellent, even more when paired with Viper4Android. Nonetheless V4A doesn't seem to catch the digital output stream used by AA.
Maybe it's just usb? My thumb drive doesn't sound as good as my Bluetooth with the same song either.
Yea, audio is transmitted via USB, so in theory the quality should be even better since it is transmitted without the SBC compression like with BT (unless you have aptx). If your in-car has a built in equalizer i would advice to use that one

The theory is not working in this case, most probably because we don't know the root cause of this weird and annoying issue.
Car equalizer is not working when there are missing frequencies. BT works perfectly, but when playing the same song, with the same device and app (Spotify, music player, TuneIn) the quality is severely degraded when using AA. No deep bass and no treble. Total loss of both ends of the audible spectrum while BT quality is superb (compared to the crappy AA quality)
I have tested this issue with a Chevy Malibu 2017, Chevy Impala 2017, Ford Fusion 2018, Buick regal 2017 and Hyundai Sonata 2018. Same degradation when using AA with different head units, different apps, Axon 7. I hardly believe it is a device issue, I believe it is a problem with the protocol. Are you experiencing this issue? I am using RR ROM.
Hi there,
I replaced my HTC 10 with the P20 Pro and since then i have really poor audio quality when using my hands-free phone system over bluetooth in my car (Mercedes). The quality was good with the HTC and turned bad with the Huawei. I looked up the settings in the developer menu and saw that the BT coded that is used is SBC. When i turn off Bluetooth on the mobile, i am able to select a different codec but as soon as i turn on BT again, SBC is selected automatically again in the menu. Is there anything i can do to permanently select another codec such as aac or aptx? On my HTC, the option for following the "standard setting" is preselected.
facing the same issue with my Ford Focus. Sound is cracking, and the only way to fix it (temporarly) is to reset the connection and made new one. but only works for a few days, then it returns....
Also waiting for a fix, and even in the latest firmware version Cl20C432131 .
Nissan Note 2012
Same problem in my Nissan. I don't know what codec my old galaxy s7 used but the drop in quality when switching to P20 pro was huge. I also cannot permanently change the codec settings. This is a deal breaker.
You should remember that there is 2 ways bluetooth working with sending audio - in handset way (low quality but allows microphone input) and in headphone way (normal quality but no mic input).
Exactly the same issue as me in my Audi. I don't know if I'm glad other people have this issue but at least i know it isn't just me or a fault with my car haha!
People the other end seem to hear me fine. Its not practical to keep connecting and disconnecting each time i want to make a call in the car.

Interesting, I'm using android auto and I believe it switches between these modes automatically. With my old Galaxy S7 I could hear a real downgrade in audio quality when the phone was responding to my voice prompts. On the P20 Pro, the voice prompt responses seem much higher quality than the previous phone but the music is much lower quality - as if it is only using a single mode.
I'm not sure about 'no mic input' though, both phones could can hear voice prompts over the music (as long as I shout!)
Nevertheless I will test with google music only and disable android auto and will report back.
(for me the music quality is always poor even after reconnecting - it does not sound like it is coming over the voice channel, it is more subtle a difference than that)

Try connection with car audio in your phone with active option "media audio"
Thanks

Thanks, I tried this and it had no effect on sound quality, but......
I need to confess a stupid oversight. It turns out that my Google Music settings specified 'Normal' quality over mobile network. I set this to 'Always High' and restored the original quality of music that I was used to.
So it seems that:-
My car has always used SBC at 44.1 KHz 16bit
Even with this low fidelity Bluetooth connection, it is still possible to distinguish Normal and High quality modes of Google Music.
Hi XDA Community
Setup:
Native Instruments Komplete Audio 6 (connected to a USB 3.1 HUB because otherwise 48V Phantom Power does not work)
Two Condenser MICs connected to INPUT 1 and INPUT2 of the USB Sound card, powered by 48V
Samsung DEX Dock
Samsung Galaxy Note 8 (Single Sim) running Android 9 (2020 May Security Updates)
Findings:
1) Signal Messenger App
recording Voice Messages seems to use 44100 Hz recording, and the USB is most likely set to 48000 Hz. This results in crackling and digital noise in the recorded audio file
i played around with the Voice Recorder (see 2) and many other things, and Signal Messenger on DEX Screen suddenly started to record nearly correctly on 48000 Hz..
No digital noise
Records Line 1 and Line 2 onto just the left side of a stereo signal. Playback of that recording plays only on Left Speaker
After rebooting, today i cannot get this behaviour back, digital noise is there and i struggle again to find a solution how to tell Android 9 to use 48000 Hz for Signal Voice Recording or any other app with the lack of settings
i tried Voice Call with Signal Messenger on DEX Screen, but the Audio was forced to Earpiece or Speakerphone, especially the other side complained about crackling in sound quality which only disappeared, when i started Signal Messenger on the Mobile Screen on the Note 8, then it used only the internal mic and the Speakerphone, and other party said the quality is really good, but not what i want with the external mics
2a) Voice Recorder (there are several) https://play.google.com/store/apps/d....app.voicenote
can choose 44100 and 48000 Hz after my USB Soundcard is recognized and it also shows recording from External Mic Notification.
If I choose 48000 Hz the sound has no crackling or digital noise, it is crystal clear, but mono, it records both inputs on a mono track, stereo setting is greyed out
if i chose 44100 Hz i have digital noise, crackling.
uses system audio drivXDA
2b) Voice Recorder (another on) https://play.google.com/store/apps/details?id=com.splendapps.voicerec
can choose 44100 and 32000 Hz and you can even chose stereo and here it works
with 44100 Hz there is digital noise, but stereo
with 32000 Hz there is no digital noise, it is a preset called FM quality and i would like to use this for voice recording for broadcasting on FM later, we run a show on the radio
3) Audio Evolution Mobile Studio DEMO Version
comes with custom audio drivers (like DAWs on Windows also use the ASIO Drivers that are invented by Steinberg Cubase)
can use all inputs from an USB soundcard for recording in any setup with any KHz or bit in mono or stereo setup
in my case this was the only tool where i can correctly record my stereo mic setup
very nice but cannot change System Settings since comes with custom LOW LATENCY driver
maybe i will buy this Actually i use Steinberg Cubase on Windows usually
4) Zoom App
i tried a Video Meeting with Zoom App on Android 9 on this Samsung Note 8 to a Windows Laptop in different country
did not work at all on DEX, crashed on the DEX screen after joining the meeting
neither external USB Soundcard worked
if you launch on the mobile only Speakerphone, Earpiece and Internal Mic is supported
video freezes for both parties if I switch to a different app and continues if i put Zoom App in foreground
5) Google Meet
runs on Samsung DEX Screen perfectly
can present my screen from DEX
did not test with external soundcard
other paties video continues to work in background
my camera that is shared to the other partie does not record if i switch Meet App to background
better than Zoom App on Android, no wonder its Google
6) WaveEditor
best Multitrack Audio Editor that I have seen so far
Works on Samsung DEX
not really for recording but for editing/cutting/postpro
Free Version has most features, but for pro editing like compressing/parametric EQ need to buy the Pro version, I am thinking about that
really good tool, I am very happy
Conclusion:
In Signal Messenger App I have also this crackling if I record a Voice Message (and it Runs on Dex), so I suppose I need to tell Android Audio Manager to use 48000 Hz on my USB Soundcard Inputs. But how? I would like to see a Audio Manager Configuration Tool, that can change this System Wide
How do I achieve this? Any Ideas are welcome. Thanks for reading and thanks for your time posting a reply. Good day.
PS, i also opened a support Case at Samsung (in Community and Support) kee p you updated if they answer.
