Package: bluez
Version: 5.54-1~bpo10+1
Severity: normal
Dear Maintainer,
It is possible to connect Bluetooth earbud headphones however the
high-fidelity A2DP audio playback sink is having problems.
First problem: The headphones are paired but often they are not showing
up in Pulseaudio. 'pacmd list cards' doesn't show them as an audio
device. At other times they did show up but it was not possible to
select the high-fidelity A2DP playback sink on them, only the low-fi
sink that is used for communictions.
At one point after completely purging:
bluedevil blueman bluetooth bluez pulseaudio-module-bluetooth
and reinstalling them the headphones connected and the A2DP sink worked.
However after disconnecting them and reconnecting, it is not possible to
get it to work again.
Here's some info about the headphones:

Not only this, but another Bluetooth audio device which previously
worked fine with a2dp has occasionally been losing the Bluetooth
connection.
It seems like the Bluetooth stack in Buster is flaky.
Here are some other bug reports that appear to be related and which
indicate that these issues have been fixed in a more recent release of
bluez:
This appeared to be a similar bug but was related to permissions with
GDM: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=863603
Ubuntu: Bluetooth headphones default to low quality headset mode and
fail to switch to A2DP when selected,
https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1845046
This bug was listed at pulseaudio but was closed due to "This bug is
closed because it was a BlueZ issue, fixed in release 5.51 by this
commit
[https://git.kernel.org/pub/scm/bluetooth/bluez.git/patch/?id=477ecca127c529611adbc53f08039cefaf86305d],
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/525
Finally, there's an section on an archlinux wiki page that deals with
this issue:
https://wiki.archlinux.org/title/Bluetooth_headset#A2DP_sink_profile_is_unavailable
There is a link there to a utility fix-bt-a2dp
[https://github.com/pastleo/fix-bt-a2dp] and on that Github page they
state that the issue was fixed with a later release of bluez.
