@SuperFico2100 Did you pass through the audio card to WSL first? You need to be able to access it through WSL before you can pass it through to the VM.

Did you pass through the audio card to WSL first?

I just tried: I've passed through the audio card using the ~/.asoundrc config and installing libasound2-plugins, playing an audio with paplay (pulseaudio-utils) or aplay (alsa-utils) works fine, but now when I try running the VM it always prints the same error over and over when trying to play an audio:
alsa: snd_pcm_poll_descriptors_reventsalsa: Reason: File descriptor in bad state

@SuperFico2100 Does the virtual machine detect the audio card in any way? Even if it does not work, it might still show up as a PCI device.
