Unstable tests

[marmarek]

pipewire-qubes got installed by this update, and qubes-vm-pulseaudio got removed. But pipewire-pulse wasn't, and plain pulseaudio remained installed. This means any app using pulseaudio API won't have sound. This could be about dependencies in the gui-agent-linux repo maybe?

BTW, tests need pw-play utility, but I can't find which package has it on Arch. Any idea?

This is included in extra/pipewire-audio.

Most likely. Instead of doing it here in qubes-meta-packages, I guess this has to per properly done in gui-agent-linux repository.

[marmarek]

Now that pw-play is installed, pipewire tests are used. And they say audio via pipewire doesn't work in Arch... I'm not sure what exactly is broken, pipewire-qubes is installed, pipewire service is running, yet no audio is played.

[marmarek]

I poked at an Arch VM with broken audio a bit, and I'm not much wiser... The pipewire qubes module seems to be loaded (according to pw-dump), there are also "qubes-sink" and "qubes-source" nodes registered, pavucontrol in dom0 shows the VM entry (which suggests the VM did connected to the pacat-simple-vchan process in dom0). But pw-play in the VM hangs, and nothing plays in dom0.

[marmarek]

Oh, wireplumber is not installed! Installing it seems to help quite a bit.

This looks like some dependency issue, but TBH I'm not sure what should pull in wireplumber. Should it be the main pipewire package? Or maybe pipewire-qubes? Or this meta-package? Or maybe something else?

[alimirjamali]

Or maybe pipewire-qubes

Yes. I believe qubes-gui-agent-linux/pipewire-qubes should pull in the required dependency. This line?

Makes sense

Submitted the PR. Also included pipewire-alsa for people who might need Alsa client support. But not pipewire-jack.
