Support for pipewire-pulse

[KuleRucket]

Describe the bug
On Arch you can use pipewire-pulse in place of pulseaudio as a pulseaudio compatible interface to pipewire. Using pipewire-pulse will completely replace the pulseaudio package. According to the config file and readme, pipewire is supported however when I try to use it I get the core dump exactly as documented in loki-47-6F-64/sunshine#216

To Reproduce
$ sudo pacman -Suy pipewire-pulse
allow removal of conflicting pulseaudio package
start sunshine

Expected behavior
Does not core dump, pipewire supported

Screenshots
See loki-47-6F-64/sunshine#216

Does it work if you set audio_sink in the config file to the default sink (pactl info will give you the name)?
It's set to capture from @DEFAULT_MONITOR@ if you don't specify an audio_sink, which on pulseaudio would be the monitor of the default sink (I believe), but it seems like pipewire-pulse doesn't support it properly.
I'm using KDE neon myself, and while it doesn't crash it doesn't actually capture any audio - but setting the sink to my stereo does make it work (though audio is also played on the host). I have to modify the code to set it to capture from sink-sunshine-stereo.monitor to make it work properly.

Actually yes, by setting audio sink to the default sink (or default source), I don't get the crash. When I tried this before I think I got the crash whether I set audio_sink or not.

With audio_sink set I now get a brief whitescreen and then moonlight disconnects with "Connection Terminated".
EDIT: ignore that, it's a different issue

Is this issue resolved?

[KuleRucket]

The crash is yes, but it still doesn't actually work so it could be closed and a new ticket be created with a new problem description.

Okay, I'm going to close this. If it something that needs to be addressed in sunshine code please submit a new issue. If it is something related to dependencies in Arch, I'd redirect you to the AUR package. Thanks!
