[vfio-users] Why does the audio from VM crackle?

[Abdulla Bubshait]

I am not the only one who has this issue, but if you emulate an audio card
you end up with occasional crackling audio output, which is sometimes
associated with drops in FPS.

I know there are ways to pass audio devices to the VM directly, but in many
setups it would be preferable to pass the audio to the host.

Does anyone know the reason the audio has distortion or crackling, and are
there any known solutions to the problem?
