okay I found a solution that works for me, and it's to disable gnome from accessing pulse and restarting it 🤷 https://unix.stackexchange.com/questions/254462/cannot-get-a2dp-mode-work-with-my-bluetooth-headphones-on-gnome thank's linux
@wxcafe thanks gnome, thanks pulseaudio
@dashie @wxcafe pulseaudio has little to do with the fact that GDM starts it's own PA instance.
@Alda @dashie I mean, computers bad,
@wxcafe @dashie Why on earth does a display manager needs to start an audio daemon ?
