In UTM 4.6.2, Linux guest complains that virtio-sound-device is "not compliant with spec version 1.0"

@osy With UTM 4.6.2, I can indeed select virtio-sound-device as the Emulated Sound Card.

However, when I select that for a VM running Alpine Linux 3.20 with Linux kernel 6.6.x, it doesn't work.

In dmesg, it complains about the virtio_snd device not being compliant with "spec version 1.0":

~ $ doas dmesg | grep -i virtio_snd
[    0.614678] virtio_snd virtio6: device does not comply with spec
version 1.x
[    0.614727] virtio_snd: probe of virtio6 failed with error -22

Ah, wait.

There is also an Emulated Sound Card called Virtio sound (virtio-sound-pci) and that one does work in the VM client.

A bit confusing that there is also a virtio-sound-device in addition to that. Maybe it can be clarified what the use of this one is, and what the difference is with the other one?

Anyway, closing this issue. Thanks. 👍🏽
