If VNC is enabled, then libvirt sets QEMU_AUDIO_DRV=none unless
/etc/libvirt/qemu.conf is set to allow output to host audio.
Clearly this doesn't do the right thing when SPICE is present at the
same time as VNC, but that's libvirt's fault rather than QEMU.

Title:
no sound in spice when VNC enabled
Status in QEMU:
New
Bug description:
Running Fedora32 with virt-manager → libvirt → qemu I noticed that I
got no sound in my spice client. The VM is configured with a SPICE-
server and a QXL display, and in addition a VNC display.
Apparently when I remove the VNC display, then the sound is routed
just fine to the spice client: I can hear it, and
`G_MESSAGES_DEBUG=all remote-viewer --spice-debug
spice://localhost:5900` mentions SpicePlaybackChannel and
SpiceRecordChannel. With the VNC server configured, such messages are
missing, and I cannot hear the sound (which is sent by the guest OS to
the virtual hardware).
