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!
