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

["Mr. Teo En Ming (Zhang Enming)" <space.time.universe@xxxxxxxxx>]

Hi,

I have successfully passed through the HD audio controller on the
Intel Desktop Board DQ45CB to Windows XP Home HVM guest.

The reason it did not work earlier was because I had forgotten to
specifiy the BDF of the audio controller in the Windows XP HVM
configuration file. So the audio controller detection did not pop up
in Windows.

After specifying the BDF of the audio controller in the HVM config, I
downloaded the SoundMAX audio driver from the official Intel website
and installed it. After a reboot, I finally have sound in my Windows
XP virtual machine.

I will post more details later on.
