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.
I have an older car (2004 BMW 330ci) with built-in factory bluetooth. All of my previous smartphones would connect to it with varying degrees of success. Because of this variation, I believe the car's bluetooth system to be "less than universal" as far as compatibility is concerned. The problem is, my new HTC One is all but useless with it! The volume during calls is barely above a whisper, and callers report that they can barely hear me. Also, while it hasn't disconnected any calls, outside of a call the phone alternatively displays " bluetooth connected" and " bluetooth disconnected", cycling about every 10 seconds.
From previous experience, I know there's a significant software component to compatibility with this system. For example my stock Nexus S 4G would connect and work well but would occasionally drop the connection. But then the paranoid android rom on the same phone would not only never drop a connection, it would transmit sms text messages and my contacts directory to the car as well. No other phone or rom has done that.
So.. some questions...
1.) Anyone else having this problem? If so, what kind of vehicle?
2.) Any other BMW drivers not having this problem with the HTC One? If so, year and model?
3.) This is probably an ignorant "noobish" one, but... is it possible to extract the bluetooth software from the nexus paranoid android rom and bring it over to the HTC One?
4.) Know of any HTC One roms that make changes to the bluetooth software?
5.) Any other advice you can give that may help?
I've tried Volume+ to no avail. Version 1.9 states it isn't fully compatible with the One's android version, and version 2.0 alpha doesn't yet have bluetooth functionality.
Thanks for your help! If I discover a solution, I'll post an update.

Hi,
I have a 2006 bmw z4 (e85) and I'm having exactly the same problem with sound level via bluetooth.
My previous phones (htc sensation xe and htc touch pro 2) worked flawlessly with the car
I would also love to find a solution to it, because there's no bluetooth firmware upgrade available at BMW's..
Same issue, but it only arose with the 4.3 update. Before that Bluetooth had other issues even recognizing my stereo, now it connects flawlessly but cycles the "Connected" and "Disconnected" message every couple seconds. 2006 avalon, but with custom stereo and system.
I think that one's bluetooth stack uses some different compression method than sensation. I dont know whether its some kind of codec or encryption method, because system sounds are loud and clear and a person's voice is quiet and with some interference.
Hope that someone will find a solution to this problem - probably downgrading bluetooth stack would solve the problem

I have a similar problem with my Acer Liquid E2 duo phone connecting to Dension 500S BT kit installed in my Audi. It works all fine when I place a call from the phone. But if I dial from my media interface, i get a very low call volume and adjustment using the car volume control doesn't work any more.
A little thread revival
After upgraiding my htc one to android 4.4 kitkat the problem is partially solved, meaning the bluetooth volume is slightly higher, but only slightly - still cannot get a clear loud sound I used to have while using htc sensation with stock ICS.
Any luck with you, guys?

any fixes to this problem yet ??
Try using "HTC car" app
I had the same problem for six months and just found a solution that works for me.
I just found out that the HTC One Bluetooth audio connection (A2DP) plays with a very different volume depending on whether the "HTC car" app is active or not.
For six months I have been playing music daily in my car using HTC One (media app: Qobuz) as source and Bluetooth as connection. The source volume was very low, so that I had to keep the audio car audio system near maximum level. Eventually, this abnormal use of my car audio system destroyed it: I had to replace the receiver, and may have to replace the speakers too.
Only this morning, after six months, I found out that when launching the media app from within the "HTC car" app, the output volume is much louder, and I can set the receiver's volume at a normal level.
I guess HTC does this to prevent ear damage when the One is connected to a Bluetooth headset. Great, but they should mention it in the HTC One user instructions, or at least on their website! It destroyed my car audio system!!
HTC One (M7)
Android 4.4.2
HTC Sense 6.0
Stock ROM
Rooted
In my case car mode doesnt solve the problem - its a bluetooth compatibility issue I suppose

Hello!
Is anyone else's Marshmallow Bluetooth Media borked? Basically after upgrade it doesn't connect to Honda's audio system any more -- it connects as a phone, but then turns off Media (so music playback, iHeart radio etc all just play on the phone). Tried to delete the device and re-pair it again. Pairing was successful, but then afterwards phone just turned off Media Audio option and I can't turn it back on.
Any suggestions?
I have a SoundBot 360 bluetooth kit for my car and I didn't have any problems streaming google play music after updating to Marshmallow. Does this happen on all your bluetooth devices?
i was able to use bluetooth today (calls and pandora) without issue aside from head unit signal occasionally not properly opening the pandora app on my phone (had the same intermittent issue on 5.1.1)
SM-G920T 100% stock OTA upgrade from 5.1.1 to 6.0.1
factory touchscreen head unit in a 2015 honda civic EX
also, just noticed something that i didn't see before... on your pull-down menu, you have the option to select which "output" you want to use when you have multiple options available. might want to check that.
Works fine for me. I did a full wipe and firmware flash though, not the OTA.
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.

Hello everyone,
Since I got my new pair of Audio-Technica m50x Bluetooth headphones (Bluetooth 5.0 version), I started having issues with the Bluetooth connection of my OP3T.
The bt connection experiences a turn on/off loop while trying to connect to the headphones. It happens sistematically as soon as the headphones battery drops below 75% approximately. No issues when the headphones are fully charged.
I have tried to connect the headphones to different devices, and they work without problems.
The only way to make the Bluetooth connection work, is to deselect 'Phone audio' in the settings of the paired device. But by doing so, I would need to give up using the headphones for calls.
I have always connected different Bluetooth devices (always 4.2 version) to my OP3T without any issues.
I have tried to wipe cache, reset network settings and even a complete factory reset. But no success.
I have the latest stock OxygenOS.
I believe it is a Bluetooth problem of the OP3T, since I have tested the headphones with different devices and they have always worked fine.
More Oneplus 3t users are sharing the same problem(cannot post links yet), but no solution has been found yet:
Similar topic in the oneplus community forum.
Have somebody already experienced such problem? Or do you know what this problem could be related to?
Thank you for your attention, and my apologies for the long post. :angel:
I have the exact same problem. OnePlus 3T as well.
Am on Android 8.0 OxygenOS 5.0.8.
I have the same exact problem. Always root my OP3T and install TWRP and install latest Magisk (my routine procedures).
Running stock OOS 5.0.8 (Oreo 8.0) and also recently bought Audio Technica M50xBT.
Same problem:
- if "Phone audio" is enabled then Bluetooth gets stuck in ON/OFF loop.
- if "Phone audio" is disabled then Bluetooth works fine (cant use the extra calling related features ) ....
I hope the Androi Pi update coming out (they already have BETA but im not trying it) solves these issues.
Because this Oxygen version fixed my "CAR BT issues" in my B7 VW Passat (2012) - just to find out for new headphones something else is not covered in the "logic in the code" dammit.
@liuk5 I did not notice the batter part you mentioned "It happens systematically as soon as the headphones battery drops below 75% approximately. No issues when the headphones are fully charged. "
I will charge mine to 100% and check it out (but obviously thats not sustainable, plus constantly topping off the ATH-M50xBT battery would decrease the battery lifespan)
