I have a Z77X D3H motherboard (http://www.gigabyte.com/products/product-page.aspx?pid=4144#ov) whose onboard audio does not show up to pass through when creating a windows 10 vm (neither does the 280x gpu hdmi for that matter either).

 

Am I completely out of luck or is there something I can do to make unraid aware of the onboard audio? I guess the kernel doesn't have a driver loaded for what looks to be VIA VT2021 codec?

Have you enabled Virtualization and vt-d/iommu?

 

 

I have enabled virtualisation yes but had completely forgotten about vt-d (my current chip doesn't support it). Nevermind, I picked up an i5 2500 that has vt-d support to test with.

 

Thanks for reminding me of the vt-d requirement!

No problem at all glad you got it sorted out!
