Car Bluetooth Audio Metadata Issues

I have just got my P20 Pro, it seems like a great phone so far, but I have one nagging issue.
When I connect my phone to my car's (2015 BMW 3 Series) Bluetooth the now playing metadata of the audio being played is not being passed correctly. So if I play audio from Google Play Music or Pocketcasts the head unit on my car will show either Unknown Track or the track data of the first item on the album or the playlist. The audio itself sounds fine and I am able to skip tracks, select new albums from the car's controls, so it seems some information is being passed correctly, it is just that the info of the track that is currently playing seems to not be working.
Has anyone else encountered this?
At this point I have to assume it is the phone, as my Galaxy S6, S7 & S8's all worked, but I guess it is technically possible that could have been a workaround put in by BMW as they were such popular phones. Hopefully Huawei will sort this out, it may be an underlying Oreo issue as threads like this suggest that Bluetooth issues were around when 8.0 launched https://productforums.google.com/forum/#!topic/nexus/E9Q2lyFYRgI

I have done some more digging on this issue and I suspect that is might be something to do with the Bluetooth AVRCP version that the phone is using. Normally in Android (since 8.0) you could adjust the AVRCP version from within Developer Options, but for some reason this is not available on this phone. My Galaxy S8 was using AVRCP 1.4, so I suspect that this phone is using 1.5 or 1.6 and my car does not like it.
I have emailed Huawei to ask for clarification. At this point it is the only real issue I have with the phone, but it will annoy me if it isn't resolved quickly. I'm going to pester BMW too to see what versions of AVRCP they officially support.

Don't have these issues in the car, head display current track etc via Bluetooth ... Use this in a Nissan

Everything works as it should with my Pioneer headunit using Spotify

I just posted something related (possibly) in the RAM/Battery Management thread - I have issues with the Audi MMI Connect app, losing connectivity and so on.....does seem that the P20 Pro handles Bluetooth (no rsap?) and background process management quite differently to my previous phone (Galaxy S8+)....also hoping quick resolution, as love the phone!

Search facility not working in car
Hi
I've just put music onto my P20 pro and it plays fine on the device and the car, however, I can't use the search facility on the car (BMW, 3 series, 2017) to change track. I can do this on the phone. Any suggestions? I put the music onto the 'Music' app (dragged and dropped from my iTunes folder- don't know if this is relevant. Any help would be greatly appreciated as without being able to use the car's search facility and come in and out of albums/ artists is useless. Should I have put the music into somewhere else?

P20 PRO and BMW - bluetooth issue
Bojanglez, did you find a solution? I got the same issue with P20 PRO and BMW X4... so it seems a problem linked to that phone connected to the BMW multimedia system.
With my previous phone, an ASUS Zenfone, everything was fine.

It may be a BMW issue to, maby P20 pro isn't compatible with BMW or Audi. I know that some manufacturers put all in to be compatible with ios and some larger manufacturers of phones. It could be that car manufacturers don't test Huawei phones and don't support them.

No Huawei Garbage bloatware issue, my is random something is normal, most times it plays music but gets stuck on providing music playing info.

Same issue here with my 2016 Toyota rav4. It plays the first track and shows the metadata but then as the tracks keep playing the metada remains the one of the first song. Definitely an issue with Huawei. Their music player works just fine. I think it has to do with the poor Google integration and their need to force that half baked apple wanna be emui down our throats. It should be Oreo but looks and feels like gingerbread.

Hi all, I have an update. I have resolved the issue, but not quite sure which of the following specifically fixed it.
Huawei software update
Renamed by phone in Bluetooth settings
Updated to the latest BMW firmware (from their site)
Messed with some of the Bluetooth settings in Developer Options on the phone
Unfortunately I did all these at pretty much the same time so I can't say for certain which one fixed it, I think it was the Huawei software update as after I updated my BMW firmware I still had the same issue and also in other BMWs I tried. I also noticed that the Bluetooth was dropping constantly in my wife's Puegeot 3008 so that's why I played with the Developer Options. For anyone interested I havethe following now set:
Codec: SBC
sample rate: 44.1khz
channel mode: Stereo
LDAC playback quality: 990kbps/909kbps (optimised for connectivity quality)
HWA playback quality: Best effort (400KB Optimised for connectivity)
HWA Latency: 50-100ms
So I now have track information and basic controls using Google Play Music and Pocketcasts. It does not seem to like letting me browse my library though, but it is at least functional.
Also I changed my car, this was not because the BT didn't work It worked in my 2015 3 series before I changed it. I now have a 2018 4 series and the behaviour is the same, track listing and skip functionality but no browsing.

I have installed the most recent firmware update on my 2 Series 2017, I see two fundamental issues. One is, by using your phone normally, no issues should arise most of the time but still random sync issues with metadata can occur. The second issue is, no matter how good your phone behave and how well synchronized the metadata is, once you open Android Auto app, everything goes to hell and you are back in square one.
To fix it, you should deactivate auto start when connected in the app (or not using it at all), erase your car from devices in bluetooth config within your phone. Erase your phone from the list in your car. Change the phone name. Start over with the synching process. Check for correct metadata in the car. If not working repeat. That should fix the problem eventually.
If you like very Android Auto very much, get used to see the songs information in your phone screen rather than the car.

I am also having the same problem, Huawei P20 Pro and Sony XAV-601BT head unit. I've tried enabling all the permissions in Spotify, cycling the connections, renaming the phone.

i have Pixel 3xl with Android 10, - Bluetooth connects fine there is no metadata - song info. this problem started with 8.1 Android version and I have not been able to get it to work. I really cant believe google cant fix this issue or even aware of it. plenty of threads on google. I think they all use Iphone, i am guessing ...this is very annoying. I have change the avrcp version from 1.4 to 1.6. no luck, also I read that turn off battery optimization on Bluetooth. no luck. anyone else here having similar issue??

Audio via Bluetooth stuttering - unusable

Hi all,
The same headphones which used to work perfectly with my Huawei Honor 8 stutter upon Bluetooth music playback to the point of unusuable. It's the kind of stuttering like there's a poor connection/bandwidth issue between the phone and the headphones. It's similar to what happened on my Huawei Honor 8 when I was washing my car and ducked my head under the car
Tried multiple apps:
Google Play Music
Youtube
Youtube Music
Amazon Music
EDIT: ONLY my Philips SHB4405 headphones suffer! Tried different bluetooth devices to eliminate the headphones, same stutter.
Tried setting the special access to the battery use: "Settings", search for "Special access". Select "Ignore battery optimisation". Make sure "All apps" are shown. Select the app you want and set it to "Allow (May drain your battery more quickly)"
Tried setting Battery settings of the app to manage manually then Auto launch, Secondary Launch and Run in background all toggled on.
Any ideas please?

It is likely their hyper-aggressive battery management software, which there seems to be no way to remove.
You may try to go to development mode menu and play around with the BT audio bit rates and codexs. Or, just take it back to the shop and exchange it for a new one.

I wish they'd just use STOCK ANDROID. who the hell do they think they are to think they know better than Google about it's own OS!!! very cross

try turn off WiFi ! - > WiFi + Bluetooth = stuttering

I'm using my phone with two BT device, one is a Jabra device I have in my car, the other one is the Backbeat fit from Plantronics. Honestly say BT communication works very well. EMUI 8.1.0.161 (C432)
Any update available for download?

funnily enough I did have an update apply yesterday but it didn't fix this behaviour. EMUI 8.1.0.159 (C782)
I have an update to my OP though. The bluetooth music streaming actually works perfectly on every bluetooth audio device I have (Radio, AV receiver, 2 x car stereos, bluetooth speaker, another set of bluetooth headphones) so I can only assume that the Huawei P20 Pro is incompatible with the Philips SHB4405 headphones! sounds bizarre to say it but that's my experience!

Bluetooth codec fix
I fixed this on my Honor 8x by changing the bluetooth codec used in the developer settings.
1. Enable developer settings
2. Change the "Bluetooth audio codec" setting value from "aptX" to "SBC"

Hi mate, check the supported codecs on your headsets. Enable developer options in Settings and force SBC codec.

Has the latest 9.0 solved your Bluetooth problem?

I have the same issue with Bose and Jabra headsets... Cheap chinese BT headsets Line taotronic seems to works fine.. I have given up trying to figure out the cause... Thing is I love the p20 Pro but this BT problem is really annoying!

Hi Guys,
I have a P20 and I love it, but had the BT audio stuttering problem in my car for a while - the radio is fine, my gf's Samsung can stream to it no problem.
9.0 didn't help, the problem persisted until... I changed the display sleep time to 10 minutes and forgot about it.
So after some testing I can 100% confirm that the stuttering happends only when the screen is off.
When I drive with the screen on, the BT music streaming works great. When I turn off the display - within minutes the stuttering starts. Turn on screen again - no stuttering.
Test it.

Happens on my Mate 10 only when screen is off. I already removed PowerGenius and had set battery optimization off to my music app. This is so annoyingly frustrating. Any solution yet?

I think I have the same or a similar issue using Beoplay H9. Changing codec to manual SBC or AAC does not work, but SBC is noticably better.
Closing all open apps or restarting bluetooth often works, but restarting the phone completely alleviates the problem. After an hour or two the problem appears again.

Can you check if the headphones are paired to anything else in the vicinity? Like a tablet or other phone? May be the problem..
Also the codecs in use make a difference too, can be altered in Dev options.
I had problems with calls with a very expensive pair of plantronics on my phone, the v6200's £275 when they were released lol.
Base didn't make a difference either Oreo all the way up to 9.1, in fact it was better on Oreo.
Doesn't affect everyone in the same way.

Paired to stuff yes but I can take them out of the question by wandering away from any of the devices for a 1-2 mile walk

Still experiencing this same problem on EMUI 9.1, even after disabling battery optimization in all music apps.

This worked for me - turn off 'Always on Display'
I was getting brief but regular strutters with my bluetooth headphones (Marley Positive Vibrations 2) but only when the p20 pro was put in my jeans pocket, so walking the dog while listening to Spotify was a pretty glitchy affair. At first I assumed being inside the pocket was degrading the bluetooth signal strength but I recently noticed that whenever the phone sensed it was inside my pocket (or in a pitch black room) it was turning off 'Always on Display' to save battery, so wondered if this was affecting the bluetooth audio connection (especially as people already suggested it was related to either display settings or battery saving options).
I disabled 'Always on Display' and this stuttering problem has been completely resolved for me (EMUI 9.1).

@theToots
Where to find the option 'Always on Display'
edit:
Found

I have this same Issue using a P20 Pro and Sennheiser HD 4.50 btnc.
This annoying audio stuttering started happening only after a software update (EMUI 9.1.0.361).
A fix that works for me is to turn my location off.

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.

YouTube stutters while using bluetooth audio

Hi,
I'm currently using my P30 Pro and it seems that there's no way to watch a youtube clip without stuttering. My colleague has got the same problem on his phone.
When using my Bose Soundsport Free , YouTube keeps lagging (only the picture, not the sound). I already tried to reset my phone, delete all data of the app, and changed the codec.
The problem also appears when connecting to my car (youtube stutters). Please note : that was only for testing.
The bose Soundsport free did work without any problems on my Galaxy S9+. I'm also using the newest update.
Does anyone have an idea?
Thanks

I think there was a similar issue with instagram also on the previous build. Are you sure you are on the latest build ?

I updated a few days after the release of the phone to EMU 9.1.0.124.
My colleague's phone was using the previous one.

I'm having same problem with Bluetooth audio streaming, I'm on latest firmware...

Huawei phones are (in)famous for aggressive battery management.
I had the music stuttering issue with MX Player on P20 Pro & it only went away if I suspended power management for the MX Player app.
I have had issues with Bluetooth stuttering as well, on Samsung, Skullcandy & other noname knockoffs, but only in public transport where tons of other bluetooth devices are live in close vicinity.
However, on he recent software version on the P20 Pro & now the P30 Pro, I'm seeing the stutters less & less.
Not a solution for your issue, just my observations.
YMMV

This is happening on my p20 recently and it's super aggravating. It will work if I shut the screen of but if Im trying to watch a video I'm pretty much SOL

Hi I found the solution! Go in developer settings and change your Bluetooth code from AAC to SBS. AAC seems to be cpu intensive, therefore causes choppy video. Good luck!

For those facing this issue on Android TV youtube app, using bluetooth headsets, go to settings -- Device Preferences -- Sound -- Under Digital Audio Format, select Auto...restart.
This solved my issue

Bluetooth audio delay

Hello, I have been intensively googling for the past 2 days but couldn't find any permanent solution to my problem, which is bluetooth audio delay. I own Bose Soundsport Wireless headphones and I have never had a problem with them when it comes to audio delay. I just bought a new P30 pro and while watching videos on youtube or in any video player I get noticeable audio delay. I found people complaining about this issue with other Huawei devices as well. The only solution I found is temporary - in developer settings changing the bluetooth codec from aac to sbc. Sadly, this settings gets reset every time the headphones are connected. For a premium device like p30 pro I would expect much more polished experience. Does anyone know how to solve this?

No delay on youtube after update .178 here.
Dont know what may be your problem.

I don't know either. I am on 185 I received through OTA. Hopefully I won't have to do a factory reset.
Are you on wifi while connected to bluetooth earphones?

Ok, realuzed it's probably related to Dolby Atmos. Turned off fixes the problem. For now.
Edit: Okay, it seems unrelated to Dolby Atmos. Sadly, it's back and I can't figure out why. Strange thing is that it only happens on this phone. I don't have any problems with my old LG G6.
I use my LG for hotspotting currently. While watching a movie broadcasted from Huawei on a TV connected to the same hotspot, there is no delwy whatsoever. I would assume there would be a delay considering the data transfer: From LG to Huawei back to the LG and to the TV. I am wondering if this would be solved by a factory reset. I have already cleared cache and it didn't help.
