I'm not sure this is just bluez and not a little of pulseaudio, but i'm still not an expert.
I pulled the source for bluez and recompiled without the enable_audio_sources.patch file using quilt: apt-get source bluez quilt pop -a quilt delete enable_audio_sources.patch quilt push -a debuild -us -uc dpkg -i *.deb This gets me audio. I've commented out everything in /etc/bluetooth/audio.conf to leave it all to defaults. Here's what I currently have to do to get working audio (after installing the patch- modified version as above): 1. Computer start 2. Attempt connection to paired A2DP device. Fails ("bluetoothd: Unable to select SEP" in syslog) 3. pactl load-module module-bluetooth-discover (endpoints registered in syslog) 4. Attempt connection to paired A2DP device. Success! Pulseaudio device created and available. 5. Open Pulseaudio volume control (to assign default audio output device). Pulseaudio crash!: Jan 22 23:07:11 chrispad pulseaudio[1955]: [pulseaudio] module-bluetooth-device.c: Failed to acquire transport /org/bluez/999/hci0/dev_00_02_3C_41_CA_0D/fd0 Jan 22 23:07:11 chrispad pulseaudio[1955]: [pulseaudio] module-bluetooth-device.c: Assertion 'u->transport' failed at modules/bluetooth/module-bluetooth-device.c:363, function bt_transport_acquire(). Aborting. 6. Attempt connection to paired A2DP device. Fails ("bluetoothd: Unable to select SEP" in syslog) 7. pactl load-module module-bluetooth-discover (endpoints registered in syslog) 8. Attempt connection to paired A2DP device. Success! Pulseaudio device created and available. 9. Open Pulseaudio volume control (to assign default audio output device). Can finally open and assign output device. Pulseaudio does seem to crash, as I receive a crash report notification after step 5, and the Volume Control loses connection to the PA server. All the while, blueman experiences connection issues to the server, particularly after "Unable to select SEP", though that may be poor error handling on blueman's side. This is on 13.04. I could upgrade to 13.10, but not sure if that will do anything for this. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1199059 Title: PulseAudio doesn't load bluetooth modules automatically(orig.: A2DP audio sink devices failed to work with "bluetoothd : Unable to select SEP" in system log.)
