Hyper-v + gpu-pv = no audio, how to remedy?

I got gpu-pv setup but have an issue with the no audio on basic session (enhanced session black screens with gpu-pv)

i’m on windows 11 x64 uefi 25h2 and latest non preview CU with an rtx 3070 ti gpu.

the guide @ the 2 Gamers 1 GPU thread mentions vb audio cable but there’s no info on how to set it up. anyone know how to do it?

i also tried parsec but it wouldn’t enable hardware encoding, kept showing a message in the rdp saying software encoding was enabled (when it wasn’t) and made it unusable.

Sorry not a solution only a suggestion for an alternative.

Have you checked James stinger’s App sandboxing project? Here
He used to do a lot of stuff for Hyper-v gpu-pv but abandoned it in favor of the sandboxing. Old project
Don’t know if it fits your use case, but just in case you missed it.

If you must have gpu-pv you might want to check out Craft Computing two games one gpu guide. Guide
Maybe his guide points something out you missed.
Also check the comments on the video they point out some stuff Microsoft changed in later updates.
