pipewire permission issue after 1.0 release

[shetozz]

In the flatpak permissions, pipewire is set to xdg-run/pipewire-0:ro this leads to audio not working if the system's pipewire version is 1.0.x, changing the permission to xdg-run/pipewire-1:ro solves the issue.

this leads to audio not working if the system's pipewire version is 1.0.x

what do you mean? socket number isn't related to pipewire version. I have pipewire 1.0.3 and socket is still named pipewire-0. Maybe if you have multiple pipewire servers running at same time then you would have different socket number but I don't think this is workable.

[shetozz]

Not sure what's going on, as I have no experience in any of this stuff, but that's what happened to me.

[Erick555]

do you still have pipewire-1 socket after reboot?

[shetozz]

Yeah, still -1 even after restarting.

[Erick555]

Is there only -1 or both -1 and -0? This is very strange situation which would break all flatpaks that use pipewire. You may ask in https://gitlab.freedesktop.org/pipewire/pipewire/-/issues about it.

[shetozz]

I just found out something even weirder, it's not just -1 that works, any number other than -0 works, and even removing the permission altogether works, but resetting it to default breaks audio, -plays mp3 files, but audio in video files doesn't work-

[Erick555]

Can you show ls /run/user/<user id number> output?

I guess pipewire audio output is simply broken on your system and audio works only when you block actual pipewire socket and use some fallback.

[Erick555]

yeah, your socket name is pipewire-0 which is right. By changing permission from pipewire-0to pipewire-1 you actually blocked pipewire access which accidentally helped because the problem is pipewire didn't work at all with flatpak (and pulseaudio fallback worked). There were similar issues about pipewire in the past.

[shetozz]

Okay, gotcha.
I followed the trace instructions in the other issue and it's just a spam of this line
