Default [Q] Bluetooth handsfree problem

I have a Sony bluetooth head unit in my car which supports handfree and audio streaming profiles. I can play my music through the head unit just fine via bluetooth. I can also make and receive calls without problem when I am listening to the radio (ie when I am not listening to my own music). However, when I am playing my own tunes and I either make or receive a call, the head unit indicates I am on a call, it mutes the music but I just get silence through the speakers.

I used to have a Galaxy S Advance and it all worked just fine without too much configuration on the phone or head unit; basically just pair them up, make sure the right boxes are ticked in the bluetooth options and thats it.

Any idea what the problem could be? I've tried an upgrade to 4.2.2 but it didn't help...
Personal Phone: Samsung Galaxy S II Plus with stock 4.2.2

Hi,

I have a similar problem. I can pair my s2 plus with cm11 from this thread to my car kit (Parrot MKi 9200). Playing music via phone on the car speakers works fine but when I place a call the receiving phone just gets loud static (and my voice very very silent).
I wanted to ask the developer of the cm11 I am using if he sees a way to exchange the bluetooth module (or what androis equivalent is) to the one of e.g. Android 4.1.2 because I know that one works perfectly. I am posting here because I havent reached 10 posts yet.

Of course I am open to other workarounds and ideas.

Thanks,
Kiesel

Default Bluetooth

Same issue here,
everything (music etc.) is okay, but the phone connection.
I'm connecting to my Ford Sync.

I can connect, but then the quality of the voice is very very bad, I can hardly understand anything...
I thing there's a configuration file in the etc/ folder, maybe that need some upgrade?!?

Hope someone can help, because I really like to keep CM11 on my phone...

Dan

How is this message supposed to be of any help? Of course we know that. We have seen a lot of threads. I have read the whole bug report including all the comments on googlegroups, I have browsed dozens of websites and googled my ass of. What I didnt find was an explanation (at this point I dont expect to find a fast solution anymore). After reading the googlegroups bug call I thought it was a problem with the bluetooth stack that apparently is being redeveloped by google. But here cooldevelopment said it isnt a google problem.
I fully understand that it must be annoying for you to see this question a million times but please understand, that it is also annoying (and unsatisfactory) to not know whats going on.

I know what you mean but i think the best method now is to wait until cooldev find a solution to this

As this is a bluetooth problem topic, i just want to ask one question. Can't use the CM 11 and ROM's based on it, because the sound problems with connection in my car. So back to stock ROM. I flashed the cooldev's kernel to get a better battery life, but after flashing, bluetooth makes the same problem as CM. Do you guys have the same issue?

Hmm, interesting. I will try this out as well. Might probably be a week though, I am leaving for holidays tonight and cant risk making my phone unusable. Maybe somebody else is willing to give it a try?

Hi,

here is a logcat of a bluetooth connection during a call on stock rom/stock kernel.
What I did:
-start logcat
-start bluetooth
-chose a contact
-call contact-
-talk for a minute
-hang up
-stop logcat

I then wanted to flash the mosh kernel and do the same again but the last time I checked there wasnt this huge plethora of different kernels to choose from. Very impressive work!
Could you tell me which one you would like me to flash and I would then redo everything?
