[Pkg-utopia-maintainers] Bug#1019888: pipewire 0.3.57-1: no/crackling sound if pavucontrol is open, 0.3.56-1 is fine

Package: pipewire
Version: 0.3.57-1

Tags: fixed-upstream

Dear pipewire maintainers,

I'm a happy user of pipewire since a few month, however since the
upgrade to 0.3.57, no node can output sound if pavucontrol is open.

When pavucontrol is open, pipewire log show the following error message

(3-4/second):
```
spa.alsa: hw:sofhdadsp: snd_pcm_avail after recover: Broken pipe
```

Starting pavucontrol after the node starts playing works a little
better: there is sound, but it's choppy.

Closing pavucontrol makes the sound working again.
Downgrading pipewire to the 0.3.56-1 version fixes it as well.

I believe this is an upstream regression: 
https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2671 (fixed in 
0.3.58 it seems, but I didn't test it).

Disclaimer: I have a fairly fine-tuned configuration for low audio
latency, for pro audio apps (recording, routing, etc). It might make
things worse in this case. So while I considered tagging this `Important`
I refrained from doing so, I might be in a corner case.

The Gnome sound parameter menu works fine (but you can't enable/disable
device profiles with it, hence my usage of pavucontrol even when I'm not
using recording apps).

Please, can we get 0.3.58 sooner rather than later?

I see there are a lot of changes in the work, and I understand you want 
to get them right,
as well as discuss them maybe, especially with the conversation going on 
currently about pipewire.

That said, can I suggest decorellate system changes and upgrading to 
latest upstream release first so this is fixed?

Thanks :)


PS: if anyone reading this needs to downgrade on **sid**, the easy way is

- adding the right snapshot in apt list from snapshots.d.o:
https://snapshot.debian.org/archive/debian/20220720T032429Z/
contrib non-free`

- and downgrade like this:

`export pwver=0.3.56-1; apt install 
{pipewire{,-alsa,-bin,-jack,-pulse},libspa-0.2-{modules,bluetooth,jack},libpipewire-0.3{-0,-modules},gstreamer1.0-pipewire}=$pwver`

do *not* do this on testing, at least not blindly, you'd need to get the 
right snapshot first ;)
