Description Daniel Savard 2014-09-01 17:43:29 UTC

I cannot get my headset to work with net-wireless/bluez-5.21-r1, media-sound/pulseaudio-5.0-r2, 3.14.14-gentoo and Gnome 3.12.

The bluetooth subsystem refuses to recognize the audio profile: a2dp-sink.

I opened a bug to Gentoo and after investigation here is the outcome. I needed to restart pulseaudio in order to bluez to make the connection. Here is the steps I followed to debug this:

The problem:

And here is what I am getting in bluetoothctl:

Then, here I restarted pulseaudio with pulseaudio -k and then tried to connect:

	0000111e-0000-1000-8000-00805f9b34fb
[bluetooth]# 

And now the device is connected properly.

I shouldn't have to restart pulseaudio in order to make this working. Seems to be a pulseaudio issue. My version of bluez is 5.21.

Comment 1 Tanu Kaskinen 2014-09-02 07:55:41 UTC

This might be caused by the bug in bluez that was fixed in this recent commit: http://git.kernel.org/cgit/bluetooth/bluez.git/commit/?id=274860fbc5fe458b4c4087f8c649387f06d68b29

Could you attach the pulseaudio log? Instructions here: https://wiki.ubuntu.com/PulseAudio/Log

Since I restart pulseaudio the bug doesn't manifest exactly the same way. I request a connection from the bluetooth audio device, it doesn't connect and I need to manually connect it. No more need for the pairing and discovering.

Comment 3 Tanu Kaskinen 2014-09-07 11:37:05 UTC

Connecting Bluetooth devices is not handled by PulseAudio. Since it sounds like the only problem that you now have is that the headset doesn't get connected without manual intervention, I'll close this bug.
