RE: [Xen-users] pci pass through of sound cards

["Max E. Baro" <MEB@xxxxxxxxxxxxxxxxx>]

As long as sound is working in DomU qemu can emulate and passthrough sound.  I had to set my configuration file as "soundhw='es1370'" for my Windows to recognize it and the sound to get through dom0.

In my browsing of pci pass through I have found a lot of information but
some of that information seems to be obsolete applying to older versions
of Xen.  I have also read that some hardware can not be passed through.

I have a windows domU and I was considering what it would take to get
sound out of it.  I figured I had two choices.  One, some how get sound
out of the windows through some drivers and into the dom0 sound card,
not likely I would guess.  Two, buy a cheap sound card and pass it
through to the windows domU.  I could then run the outputs of one sound
card into the inputs of the other.

Any chance I can get some up to date information on pci pass through for
sound cards.  I would rather not buy unless I knew it was possible.
