USB audio stopped working between p7 and p8

Hi list,

I recently upgraded my home server with musicpd from 13.1-RELEASE-p7 to 13.1-RELEASE-p8, and now USB audio stopped working.

The USB DAC identifies the input as 44.1kHz PCM, which, with the sysctl’s that I set really should have been 192kHz to begin with, but there’s also no audio from it at all. I figure that if I can get audio working at all again, even at 44.1 kHz, I can take it from there again. To focus on the problem, I’ll leave musicpd and virtual_oss out of the equation for now...

For the upgrade, I used:
freebsd-update fetch
freebsd-update install

Before the upgrade, the USB DAC registered as pcm0 while now it registers as pcm2, so the sysctl’s applied to the device now obviously go to another device (namely one of the HDMI outputs), but even then I should get audio from it.

I’m at a loss as to what’s the culprit here and am starting to think that it’s a problem with the release or with the newer GENERIC kernel.

I’d appreciate help fixing this. Thanks in advance.
