Heym
i just did some testing with various devices and BT-receivers over the last days. It is known that audio over bluetooth may be one second out of sync, if the receiver is only capable of using the sbc codec and the sender has to recode the stream. Funny thing is: using my Nexus 7 with latest SlimBean Beta, i don't have this delay. Same setup* with my HTC One (also running SLimBean Beta), delay is there. Any dev could explain where exactly the magic happens? I don't believe in any performance issues regarding the recode, as both devices are pretty much high end. Perhaps some tweaking on the bitpool-settings?

Since I can't post directly to the ROM thread, thought I'd post here.
Installed the ROM and the ringtone audio fix. All is working swimmingly on the device.
Re-paired the phone to my JVC head unit in my car. When playing back audio via Bluetooth, any audio streams are playing back at what seems to be 1/2 the frequency, therefore the pitch is shifted upwards- basically a chipmunk effect. This is happening with ANY audio stream to the head unit- music, TTS output, google maps voice prompts, video playback.
I deleted and re-paired devices. Wiped Dalvik cache and the cache mount. Still the same problem.
Any ideas? Is this a generic cyanogenmod bug that crops up? No problems like this with CyanVivo 10.1 4.2.2.
Thanks!

It's caused by audio fix. You can replace audio.a2dp.default.so with the one from Stable #4 and you'll have correct audio playback back =)

A huge thanks to you both- I've done the replace, haven't tested it yet but hopefully this'll do it!
UPDATE - tested and working as normal after replacing the file mentioned by theQwertiest- thanks again!
Hello World
Hi, guys.
Saw this post about bluetooth in CyanVivo10.2.
I was using 10.1 with BT headset and everything was almost fine.
Then i decided to move to 10.2 stable 4 and when i tried to check BT headset i have found some extreme cracking noise when listening some audio. So i check my BT headset with other phones but all was fine with it. Trick with switching files doesn't work at all (even with 1.5x speed cracking noise is still present).
In order to find a solution i checked other versions of szezso's 10.2 (stable 4,5) and noticed that this "cracking noise" is not so noticeable in Troj80's version (stable 3) of this rom. The solution of this problem was found in CyanVivo X where this noise was absent. As i understand the trouble lies in A2DP and Bluetooth files.
Update:Checked VivoKat 4.4 for this noise in BT headset and I haven't found it there.
Maybe someone who are more skillful has some ideas of this trouble?
Question to Szezso:
Is it possible to insert files from CVX to CV10.2 and will it work ?
I have a question about the tablet that I can't verify right now: does the Transformer Pad support more than 2 channel audio like many Android devices DON'T? I have this experience from phones, other tablets and even Chinese MEDIA PLAYERS all running Android that it doesn't really support 5.1 channel audio at all in stock mode. Something on a very low level as I understood, but NOT hardware related. The question pertains to audio over HDMI as well as the 3.5mm audio jack.
If the TF701T doesn't run audio at more than 2 channels by default, then is there any know method of getting it to do it? Thanks in advance!

I'm just now installing my apps on my new 701 after unlocking it. But, I just came over from the 700 and used MX player. Should you decide to use that app, check this out:
http://forum.xda-developers.com/apps/mx-player/mx-player-custom-codec-dts-support-t2156254
I have both a ME57C and ME572CL, running 5.0.1 WW, and they exhibit the same problems with bluetooth, which seems to rule out a unit-specific problem.
1/ BT audio works fine in headphones mode (ie stereo listening only), quality wise, but fails as a headset on the audio-in front (tested with two different BT headsets, including a JABRA BT3030) : audio in comes garbled and clipping to the point of uselessness.
2/ Whenever BT is active, it seems to interfere with WiFi networking, leading to frequent drops and reduced throughput on WiFi connections (both TCP and UDP).
Other features of BT seem to work OK (file transfer, keyboard/mouse connectivity, etc) although I haven't tested those extensively.
Anyone with similar issues or clues as to fixing the problem(s) ?
Have you contacted ASUS to ask for support or at least to make a bug report?

Not yet : I'm asking here first to see if it's a non-official-yet-known issue (I couldn't find anything on the ASUS support resources), my experience being helpdesks work best when the users do their homework.
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??
This is a long shot.
I have a pair of Bluetooth 4.1 Minirig speakers that can be set in stereo mode. However when in stereo mode one channel experiences dropouts. Running in mono mode is fine.
The issue is with the Nokia 7+'s Bluetooth transmission as when using other Bluetooth enabled devices to power the speakers the issue does not occur.
Anyone else had this issue when connecting stereo speakers or headphones and know of a solution?
I have checked: System > Developer Options > Bluetooth Audio Codecs and tried changing these setting but the changes did not "stick" and problem remained.
Maybe there is an alternative setting somewhere that can be tweaked.
Thanks in advance.

I'm also having this issue: whenever I'm connecting my N7+ onto the car's audio system via Bluetooth I have to change the codecs to the correct one every single time to make it properly work (have sound/audio at all). The settings also don't stick or are not being saved. Also looking for a solution for this, unless an update miraculously fixes it.
Same problem here when connected to my car by bluetooth. Occasionally there is a dropout. This does not happen when my friends connect with their phones (oneplus 5, samsung, allview. or my old lg g4).
Changing the bluetooth audio codecs does not work as it does not remain selected and it switches to default. This, as i understood, happens on android 8 and has been resolved in the Pie beta and should be ok in the final Pie release.
When I raised the issue with the superbly talented nokia tech support they either act surprised as if its an unique issue to you or send you a list of compatible bluetooth protocols. Are we expected to change our cars and speakers to make the phone work?
I had this issue after installing garmin connect. Theres a thread over in the garmin forums (forums.garmin.com/forum/into-sports/garmin-connect-mobile-application/garmin-connect-mobile-android/1375800-audio-streaming-issues) about it. Also on the nokia forums (community.phones.nokia.com/support/discussions/topics/7000022239/). Seems to affect some phones on 8.1
Anyway, I'm on Pie beta now and the problem has gone away.
