"Connection failed: Stream setup failed" when using A2DP

Question

I'm trying to use my PC as a A2DP sink for my Nexus 7, but I can't seem to connect.

The bluetooth dongle I'm using is the ASUS-BT211

Things that I have tried already:

• Adding Source to the pulseaudio "Enable" line.
• Adding Socket to the pulseaudio "Disable" line.
• Installing all bluetooth packages.

But still, it's not fixed.

Its not an adapter problem. It works fine in windows.

Solution

I had a similar problem with my device. I own the bh-905i nokia headset and at first i wasn't even able to pair it, using my bluetooth dongle. This started happening after updating Ubuntu from 12.10 to 13.04 using livecd. My kernel is up-to-date. So: ->The device was detected by blueman, but couldn't pair by any means. ->After adding 'Enable = Socket' to the General section of /etc/bluetooth/audio.conf, i could pair it, but wasn't able to use a2dp stream. The error was "failed to change profile to a2dp". ->the headset appeared on the output tab, but it did not work at all (even though it was paired).

After struggling around a lot, i did this:

sudo alsa force-reload
sudo killall pulseaudio

restarted pulseaudio (alt+F2 pulseaudio)

then i added these lines in /etc/bluetooth/audio.conf

in [General] Disable=Socket

in [Headset] changed HFP value to HFP=false

and in [A2DP] SBCSources=1 and MPEG12Sources=0

then i restarted the bluetooth:

sudo restart bluetooth

and it WORKS now.

Unfortunately, if i disconnect the headset during the session i have to restart alsa and pulseaudio before trying to connect again.

Also, i change the profile to a2dp ONLY on blueman, because if i try to do that at the output tab of the sound manager (alsa, i think), i fail.

Bear with me, please, i am not an expert. And english isn't my first language. good luck!

Did you try if this still works? askubuntu.com/questions/2573/…

nope, it does not work :(

Still reproducible?

I don't quite agree that this question should be closed as being very specific. This is a common problem with many bluetooth setups and headsets, and it seems the most common fix is that the pulseaudio bluetooth module isn't loaded. You can fix this by first running: pactl load-module module-bluetooth-discover
