Yea, output:

packages installed
pipewire-qubes.x86_64 4.3.11-1.fc42 qubes-vm-r4.3-current
382

Last one and I have no more idea, it might be something that changed in Q4.3

I will test it after clean installation, in few days.

Did you made sys-audio on base of minimal template or xfce template?

Welcome to AudioVM Hell. I’m right here beside you.

I spent months trying to get mine to work, then finally discovered it won’t work when audio is going out over HDMI. I had to buy a usb device to output audio to get it to work (and that device does bad things to the sound quality) so I ended up, after all that work, just not using it even after I got it to work.

389

That’s why posting real output of command and not what you think is relevant is essential - nobody would guess what output is used if user says

I have very similar Intel sound as you

I followed guide with 4.2.4 and its worked, but after distro-upgrade to 4.3rc2, when any qube with sys-audio as audiovm starting - i got notification - “Denied:admin.vm.property.Get+is_preload from sys-audio to qube_name”
My policy file exactly like in guide. I already recreate all audio-qubes, not worked. Need i change something in policy or this is bug after update?

391

Where in this guide you’ve seen admin.vm.property.Get+is_preload in policy?
Let’s me guess - instead of using policy that had been posted here you’ve used policy from pre 4.1 salt formula.

392

thanks for reply, but no, no salt formula used, i just followed guide. Even policy i just copied to file from first post and moved to dom0. And its worked on 4.2, problem only with 4.3.
this is my sys-audio policy file, but how i said - its just a copy

Question to more knowledgeable, should he add this policy?

admin.vm.property.Get   +is_preload   sys-audio   @tag:audiovm-sys-audio   allow   target=dom0
394

Yes. Opened PR to fix it:

395

Is this for 4.3 only or 4.2 could benefit from it as well? I don’t have this policy in 4.2 and have no error.

396

Only useful on 4.3 and beyond.

Thanks and @KitsuneNoBaka thanks, updated the guide with this addition
