have you been having this bad performance with pulseaudio/pipewire? Are
you using alsa for playback/recording in the guest?
I am asking because this was my setup and I was wondering if it affected
the code I ended up with. For me I had normal playback, except for a
short delay at first (maybe something to do with alsa buffer lengths, I
am not familiar with ALSA much).
If you can share your guest and host setup you used for this I can try
replicating it.
