Hello,
I'm running FreeBSD 12.1 release host with the HD bhyve audio patch
from 13-current.
On a OpenSUSE 15.2 bhyve guest, audio works perfectly fine. However, on
FreeBSD 12.1 only noise comes out. Using /dev/dsp4 (which is a USB sound
device), audio works fine, but not on /dev/dsp0, the default sound device
on my system.
I see the following relevant errors:
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout,
channel dead
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout,
channel dead
pin dump from FreeBSD 12.1 VM.

I tried sysctl dev.hdac.0.polling=1 with no success.
Note that: The above problem is also reproducible on 13-Current

Any help is appreciated.
Kind regards,
Ali
