Nevertheless, I tried to give bluez-alsa a go but I failed to kill pulseaudio. It would always start back up as the GDM user. > >> [0]: >> https://wiki.debian.org/BluetoothUser/a2dp#Refused_to_switch_profile_to_a2dp_sink:_Not_connected > > The second workaround requires writing a configuration file to the gdm > user’s home directory.

I'm unsure how to modify GDMs configuration, however. -- Matt
