Example of soundcard working in win10 VM via passthrough. Comments include steps.

Screenshot of example Windows 10 VM working with RealTek sound card passthrough. The exclamation point for the "Intel(R) Smart Sound Technology" (Intel(R) SST) OED device is a red herring and is fine.

Here are my notes to get this physical device running under a Windows 10 VM:

You need to force the device expanded above to use the RealTek driver. I was able to force it by *extracting* rather than installing the sound driver from the Lenovo site. Selecting update driver on the sound device listed under "Sound, video and game controllers", and from there I did:
"Browse my computer for drivers"
"Let me pick from a list of available drivers on my computer"
"Have Disk"
Browse to: C:\Drivers\Audio\201211706.15485923\Realtek\Codec_8975.1\HDXLVSST.inf
Press Ok
You should see "Realtek High Definition Audio(SST)" as an option. It's the only option for me)
Next
Yes
Restart the VM when prompted
