I'm running a RHEL6 as a development desktop with Fedora 14 (multimedia stuff) and Win XP (corporate email and calendars) running on it as KVM VMs. Everything runs great except for audio pass through.
If you use Fedora virt-preview[1], or Fedora 15 then you can use SPICE which handles bidirectional audio [1] https://fedoraproject.org/wiki/Virtualization_Preview_Repository
Audio works on the RHEL host. Both VMs see sound cards provided by the VM, but no sound is forthcoming. I have tried adding a PCI audio device from the physical host to the Fedora VM, but then it refuses to boot. I remember reading that physical hardware can only be passed through to VMs if it is not in use on the physical host.
Any suggestions on how to get audio pass through happening? How can I get the host to "relinquish" the audio device so that a VM can use it?
Thanks
