I'd like to ask if anyone managed to get USB audio passthrough working? In order to minimize PCI passthrough usage (I get audio dropouts on PCI audio passthrough (Intel ICH audio) lasting 10-30 seconds every few minutes), I got a generic USB audio adapter. It works fine on bare metal but in domU all I get is loud crackling noise instead of sound.

Could this be related to Xen USB passthrough being limited to USB 1.1 and the USB audio possibly requiring more bandwidth than that?

Has anyone got USB audio passthrough working successfully and reliably? What USB sound module did you use?
