For what it’s worth: if you have a setup that doesn’t require pulseaudio it is possible to use bluez-alsa (running bluealsa as a daemon) and configure it to use the a2dp profile. I’m using this on a headless “server” in the living room to send music to bluetooth speakers. > [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. Is this something that we could do in the gdm service configuration? -- Ricardo
