Source: pipewire
Version: 1.0.0-1
Severity: important
Tags: a11y

Dear Maintainer,

after a recent upgrade, my BT headset (for lack of a better word, see below) won't connect anymore.
I always get
Failed to connect: org.bluez.Error.Failed br-connection-unknown



* What led up to the situation?

On Dec 6 I upgraded and since the my BT thingy does not connect to my PC anymore.
I am hearing impaired and need to use a BT thingy called RemoteMic+ (by Starkey) to be able to listen to music or make calls/attend meetings via PC. So, this is a major issue for me.
Among others these packages were upgraded:

firmware-iwlwifi

libpipewire-0.3-0
libpipewire-0.3-common
libspa-0.2-bluetooth
libspa-0.2-modules


* What exactly did you do (or not do) that was effective (or
ineffective)?

First I downgraded firmware-iwlwifi to version 20230210-5 -- to no avail.

Next, I downgraded

libpipewire-0.3-0
libpipewire-0.3-common
libspa-0.2-bluetooth
libspa-0.2-modules

to version 0.3.85-1 again -- and things started to work again.
Since those packages depend on another, I couldn't downgrade just one, hence the report on the source package -- but I suspect a change in libspa-0.2-bluetooth to be responsible.

Resumed from hibernate today and again got the error

Failed to connect: org.bluez.Error.Failed br-connection-unknown

despite downgrading those 4 pipewire packages.
After reboot and _before_ logging on to KDE, I switched to a console and
connected the RemoteMic+. That worked.

After login the RemoteMic+ still was connected and found by PulseAudio
with both A2DP and HSP/HFP and works.

May there be some miscommunication between bluez and PulseAudio?

(I fail to understand why _any_ PipeWire stuff is pulled in at all when
I use PulseAudio _only_ -- PW fails miserably to work with RemoteMic+,
even in version 1.0.0).

Did you try downgrading only firmware-iwlwifi to the last working version
without downgrading pipewire? Was the kernel updated at the same time?

If you can confirm that the problem comes from pipewire, it's worth filling
a bug report upstream at:

https://gitlab.freedesktop.org/pipewire/pipewire/-/issues

Best regards,
Dylan

That was the first thing.
Only after that didn't help I downgraded those four packages.

From my POV I _don't_ use PipeWire -- I have no idea why those packages
are pulled in since I sue PulseAudio.
Since I don't know what exactly happens I am unable to say if it is PW
related (and if it were, wouldn't that make it a Debian issue since I
don't use PW, but PA and do try to actively avoid PW?).

Seems to be solved with the latest update I ran on Friday (all 4
packages to 1.0.0.-3).
