[Q] Cyanogen Bluetooth Headset Audio Feedback

I believe I have found an issue with the latest (stable + nightlies) cyanogen mod rom with Bluetooth headset audio, and before I go about posting to the Dev thread I wanted to get some help with understanding how or what info a need to gather.
I have a car stereo that has support for Bluetooth (both media and voice), and whilst the phone syncs to the unit and plays music just fine, when trying to place a call, all that can be heard is a loud buzzing when the call is connected (@ both ends).
The stereo is functioning correctly, and works fine for both voice and media with my SGS2 (also running cyanogen). I also have the same model stereo in another car, and the problem manifests on this unit too.
Prior to flashing cyanogen I was using other roms (both standard and mod's) and never had any issues with voice calls.
I have tried changing the baseband, and ril but this had not made any difference. I have also paired with other headsets and they work fine, so this is down to some compatibility issue with the stereo and Cyanogen's Bluetooth stack settings, I think.
Before posting this as a bug, is there anything else I should try, and if not what info do I need to gather (other than version numbers etc) to ensure I give the dev's enough info to work with?
Thanks

If it's in stable, use the issue tracker.

Weird problem with speakers and mic

I have a problem with my unrooted Xperia Z with a locked bootloader. My main speaker does not work for any media like music games or videos, but works fine for loudspeaker calls. Also the earpiece speaker doesnt work at all. Another problem i found was that my microphone would not work at all unless it was in a call and i was using loudspeaker. The final problem is that when ever i plug in my earphones, google now pops up and sometimes my phone starts playing music automatically throught the earphones, when i remove the earphones, instea of stopping the music continues but the speakers dont work so it just keeps playing them silently. If anyone knows the soultion to this, please respond as ive searched everywhere and i have not found one solution yet.

UPDATE: i used the application soundabout to reroute the audio and the calls are now fine, the only problem is that when i plug in my earphones the google now problem persists. If i plug in earphones with a mic, i dont get any of these problems and everytime i want to use my internal speaker for media, i have to manually re-route the audio to them. Anybody know a solution to these 2 problems?

I do have the exact same problem, I tried different ROMs and Audio Mods (at the moment I've got a stock ROM) without any change.
Did you somehow fix it?

Exact same problem, i run stock android 5.1.1 build 10.7.A.0.222 locked boot loader. Problem suddenly came up last week during vacation, quite some time after I did OTA upgrade to 5.1.1 - so this is not related to ROM updates.
After installing soundabout (thanks for the hint) the rerouting did not work immediately - i had to set phone to earpiece and media to speaker in the app and reboot for it have an effect.
I think the root cause is, the phone thinks there are headphones connected, when there really aren't. If I use the UKW radio app, it starts and shows headphones as output-icon right away - it should actually complain that there is no reception without phones because the antenna (headphone cable) is missing. Since it doesn't complain I guess that's the culprit.
Any hints how to fix that, without using a rerouting app? (kinda stupid, using bluetooth speakers and so on now needs a manual setting change in soundabout).
I have that phone for more than 2 years now and used headphones maybe twice with it, so a busted headphone-jack is out of the question too.

Guys give it a try.

Thanks Ess Arr, that really works!

CM 12.1 droid turbo Bluetooth calling not working

I recently flashed CyanogenMod 12.1 nightly on my droid turbo. I Have had a good user experience so far, although there is only one issue that is really effecting my decision of using this ROM as my daily driver. My phone has no audio during Bluetooth calling and the microphone is not working as well. I'm not sure if this is a known issue or if there is a fix available at this time. I would greatly appreciate any responses in this thread troubleshooting the issue, so we can all resume safe hands-free driving.

Do you happen to be using the 11/29 nightly? I haven't tried any other newer release yet, but I have been able to successfully connect via bluetooth to my car and stream audio. I've had no indication of it failing. The one thing that got me at first when connecting to my car and streaming was that bluetooth has it's own volume control (which I turned up to maximum on my phone). I'm not sure that would explain the microphone though (if it's even related to your issue).

Depends on the bluetooth device you have. My Jawbone ICON earpiece works fine, and my Pioneer car stereo makes calls fine. Other people have had some issues. The dev says he needs a logcat for missing bluetooth configurations.

Also for the bluetooth sound not playing issues, I'll need a logcat for those, since it's possibly a missing configuration for some of them.

And you've gone into the phone audio settings (when it's connected) to make sure your mic audio, etc wasn't turned down? Audio settings change when Bluetooth is connected...
I use Volume Control Plus and put a shortcut on the desktop so I have quick access to all the phone volume settings.

yes I have made sure it is turned up on the head unit and the phone when connected and I have also tested when in a call selecting Bluetooth toggling back and forth from ear piece speaker but no change

This is why I ditched cm12.1 and went back to stock. My bt headset worked with music but no phone calls.

In Car Bluetooth Handsfree Issue (No Sound, No Microphone)

Symptoms:
Phone connects to the car just fine. Streaming audio from Spotify works great, with all track metadata showing on the car's screen. However, phone calls will not work. I can place the call using the car's built in controls and the phone responds as expected - the target caller's phone rings. But.....I can't hear anything through the car nor can they hear me when they answer. I have to always re-route the call to the phones speaker which is really frustrating. Same issue if they call me - music mutes ready for the incoming call, I answer, silence..... (until i force the call through the loudspeaker)
Car's Tested (all the same):
Hyundai i30
Audi A6
Land Rover Discovery
ROMS Tested (Cache all wiped between installs):
OOS Nougat (Stock, Locked Bootloader)
LineageOS 14.1
OOS Oero 5.0 (Relocked Bootloader)
OOS Oreo 5.0.1 (Locked Bootloader) - current
Is there a ROM or Kernel that would fix my problem? This used to work when the phone was new, but didn't fancy rolling back to the original firmware if possible - I'm become accustomed to the new features in Oreo

I've had the issue where the music would not play, but phone calls were working correctly. In my case I went to the Device Bluetooth Settings in my car and had to enable the ability for Music Playback. Also had the option to enable/disable calls and Pandora.

Is there a solution by now? I have exact the same issue, tried several Roms and different handsfree. Switched several settings in bluetooth options. A mounth ago I opened a ticket on oneplus support but no solution till now.

Question Spotty stereo speaker

As of the last few days the stereo speaker on my zenfone 8 has stopped working in some applications.
For example spotify, netflix and youtube no longer output via the stereo speaker, but just out of the top speaker.
If I make a phone call the speaker functionality still works great.
I am running the stock rom without root and did recently receive an update, but i don't remember if this issue already existed prior to that.
Is anyone else experiencing the same thing?
