When we use Spice in a virtual machine under KVM/qemu/libvirt, the QEMU_AUDIO_DRV is set to spice by default.
My host (debian-Stretch) use a good sound card (Xonar DX) and a better sound driver (pulseaudio,alsa).
How to use in a virtual machine spice for the graphic aspect and pulseaudio or alsa for the sound aspect (whatever the guest OS) ?
Note 1: in the domain.xml, I added:
<qemu:commandline>
<qemu:env name='QEMU_AUDIO_DRV' value='pa'/>
<qemu:env name='QEMU_PA_SERVER' value='/run/user/1000/pulse/native'/>
</qemu:commandline>
Now, in domain.log, I see:
QEMU_AUDIO_DRV=pa QEMU_PA_SERVER=/run/user/1000/pulse/native
Well but I don't know if my guest uses pulseaudio or not because domain.xml has the following section:
<sound model='ich6'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>
Note 2: other try:
<qemu:commandline>
<qemu:env name='QEMU_AUDIO_DRV' value='alsa'/>
</qemu:commandline>
No sound.

PulseAudio normally accepts only a connection from one user. To mitigate this you could either
- run QEMU as user 1000 - Edit
/etc/libvirt/qemu.confand add/changeuser = "<user>"or - allow PulseAudio to accept anonymous connections.

My solution works for pulseaudio (with the 1000 user) but not with alsa. Shall I also remove the ich6 section ?
