i tried adding GlobalSign Code Signing Root R45 into root ca in windows cert manager. also tried adding intermediate cert R45 CA 2020. I don't know what I am supposed to do on windows 11 to make audio work

Running vdd in hyper-v vm with gpu-p (windows 11)

I have encountered the same problem with the same error with the same msg. Virtual Display Driver works without problems.

My guest is running Win11 Pro 24H2 on a kvm with gpu passthrough

in case it helps anyone, I am currently using this https://vb-audio.com/Cable/index.htm to be able to have sound inside the VM and works just fine.

well that did get me a audio output,
but RustDesk is unable to capture audio to vb-audio.com driver 🤔 wonder if that's a RustDesk issue or a vb-audio driver issue

Edit: fixed the vb-audio RustDesk issue by manually specifying rustdesk input audio device (using "default" did not work, even though there was only 1 other option, but explicitly specifying vb-audio did work)
