Audio Busted with OSS Errors in libvirtd (qemu kvm)

I've had a virtual machine (also arch) running for months and with a recent update, the audio stopped working. Initially, there was a permissions issue, which I solved by running as my user. A subsequent recent update busted it again.

I set in `/etc/libvirt/qemu.conf` user and group to "root" temporarily and commented out "vnc_allow_host_audio".  I connect to the VM through SSH. I do not use VNC and I do not use SPICE.

This is the error that appears in the domain's log:

Domain id=2 is tainted: high-privileges

I have no idea why it's trying to use OSS nor do I have any idea how to fix that.

This is the relevant section of the domain XML:

<sound model='ac97'>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>

Thanks!!!
