| + | |||
| + | |||
| + | ===== Configuration GDM ===== | ||
| + | |||
| + | Troubleshooting: Refused to switch profile to a2dp_sink: Not connected | ||
| + | |||
| + | Bluetooth headset is connected, but ALSA/PulseAudio fails to pick up the connected device or there's no device to pick. This happens because GDM captures A2DP sink on session start, as GDM needs pulseaudio in the gdm session for accessibility. For example, the screen reader requires it. See 805414 for some discussion. | ||
| + | |||
| + | ==== Workaround 1: disable pulseaudio in gdm ==== | ||
| + | |||
| + | |||
| + | In order to prevent GDM from capturing the A2DP sink on session start, edit /var/lib/gdm3/.config/pulse/client.conf (or create it, if it doesn't exist): | ||
| + | |||
| + | <file config /var/lib/gdm3/.config/pulse/client.conf> | ||
| + | autospawn = no | ||
| + | daemon-binary = /bin/true | ||
| + | </file> | ||
| + | |||
| + | |||
| + | |||
| + | After that you have to grant access to this file to Debian-gdm user: | ||
| + | |||
| + | <code root>chown Debian-gdm:Debian-gdm /var/lib/gdm3/.config/pulse/client.conf</code> | ||
| + | |||
| + | |||
| + | You will also need to disable pulseaudio startup: | ||
| + | |||
| + | |||
| + | <code root>rm /var/lib/gdm3/.config/systemd/user/sockets.target.wants/pulseaudio.socket</code> | ||
| + | |||
| + | In order to auto-connect a2dp for some devices, add this to /etc/pulse/default.pa: | ||
| + | |||
| + | <file config /etc/pulse/default.pa> | ||
| + | load-module module-switch-on-connect | ||
| + | </file> | ||
| + | |||
| + | |||
| + | Reboot. | ||
| + | |||
| + | Now the sound device (bluetooth headset) should be accessible through pavucontrol and standard audio device manager. | ||
