Where can I find documentation on these restrictions?
You can''t just use the device in both your dom0 and domU guests;
multiple drivers hammering at a device would be bad news :)
Anyway, if you want to expose your sound card to a domU, you need to
do PCI passthrough. This will prevent any dom0 drivers from grabbing
your sound card, and allow a domU guest''s driver to do so instead.
I forget the syntax, but a quick google should do the trick!
