RE: [Xen-devel] Re: Audio Controller Passthrough to Windows HVM Guest

["Han, Weidong" <weidong.han@xxxxxxxxx>]

We successfully passed through audio controller to hvm guest before (with 
2.6.18 dom0), but we didn't try it for a while. 

Can you see any error messages in 'xm dmesg' or qemu log?

Regards,
Weidong
