Package: pulseaudio Version: 10.0-1 Followup-For: Bug #845938 This is still an issue in Debian stretch: the gdm3 package runs pulseaudio, which takes over the bluetooth device and makes it impossible for regular users to connect to their bluetooth device using the hifi A2DP sink. See #805414 for more details on that side. There's a workaround for gdm3 (disabling the BT sink in gdm), so I'll leave that aside for now and focus on the basic issue here.
>From what I understand, the whole problem here is that PA doesn't suspend the BT sink when it's not playing any sounds. Just like ALSA, when no sound is playing, PA should give up the audio device and allow other PA daemons to playback on the device. This is not a problem for regular (ALSA) sound devices because that is correctly implemented there. Therefore, I would conclude that the underlying bug here is that PA doesn't release the BT sink when not playing sound. There are many bugs reported upstream regarding this issue, but the one I found the most promising is this one: https://bugs.freedesktop.org/show_bug.cgi?id=57167 ... where an actual piece of code is outlined as being the culprit here. There's another issue regarding BT sink sync that may be relevant, although I'm not sure I understand the details here: https://bugs.freedesktop.org/show_bug.cgi?id=45040 ... it may be the other way around... There is also a more generic upstrea bugs regarding this exact issue: https://bugs.freedesktop.org/show_bug.cgi?id=92102 There are also 54 bluetooth-related bugs filed against pulseaudio here, which I haven't thoroughly reviewed: https://bugs.freedesktop.org/buglist.cgi?quicksearch=product%3APulseAudio%20bluetooth So I'm not sure where to forward this, but it's certainly something that should be fixed in pulseaudio, in my opinion.
