I can't seem to figure out how to post on the thread without directly replying to someone.

Anyhow, I've got a PowerEdge T320 on the latest firmware.

Installed ESXi 5.5 U3.

Created a Win10 VM.

Passed through my AMD FirePro W7000 and USB 3.0 PCIe cards.

Got their drivers installed.

And bam, I get working video/mouse/keyboard and even "audio".

But the AMD HD Audio is only giving me stereo.

I'm not getting any Dolby Digital, DTS, etc.  Nothing but stereo?!?

Any suggestions?

I'll be trying a Win7 VM soon, but those take forever to load up all the latest MS updates before I can really test it.
