Qemu 9.1.1-1 breaks virt-viewer audio output through spice

The upgrade of qemu packages from 9.1.0-2 to 9.1.1-1 broke the audio output of my Ubuntu 24.04 guest machine. Audio is routed through spice using `virt-viewer` for interaction

The related virt-manager config for the audio device looks as follows

    <sound model="ich9">
      <address type="pci" domain="0x0000" bus="0x00" slot="0x1b" function="0x0"/>
    </sound>
    <audio id="1" type="spice"/>

After the upgrade no application is found to play sound on the host.

After downgrading all qemu packages to 9.1.0-2 and restarting the VM the `virt-viewer` application plays sound again

sudo pacman -U qemu-*9.1.0-2-x86_64.pkg.tar.zst

Is there any indication that this is an Arch Linux specific issue? I think I would just report this upstream and see what they have to say about it ..

UP!

I have the same problem.
For audio from web stream I need to switch between virt-manager and spice viewer. The guest vm no play sounds anymore....

Re: Qemu 9.1.1-1 breaks virt-viewer audio output through spice

Hello all, I've opened an upstream report for this: https://gitlab.com/qemu-project/qemu/-/issues/2639. There's a discussion on the Looking Glass discord as well.

Re: Qemu 9.1.1-1 breaks virt-viewer audio output through spice

Same here.  Looking at the looking glass output, audio output is set up correctly:

[I]   3854734111             audio.c:159  | audio_init                     | Using AudioDev: PipeWire
[I]   3854749441                ps.c:644  | ps_connectChannel              | PLAYBACK channel connected

However, the moment I run anything that produces audio, it disconnects:

[I]   3861640088           channel.c:258  | channel_internal_disconnect    | PLAYBACK channel disconnected

A superficial glance at their codebase and what has changed from 9.1.0-2 to 9.1.1-1 suggests that the addition of line 505 in hw/audio/hda-codec.c, function hda_audio_setup(), might be the culprit?

    hda_close_stream(st->state, st);
