I've recently installed FreeBSD 12.1-RELEASE-p3 and I'm having some
issues with many of my audio devices. I'll start with one, my Yamaha
MG12XU mixer and audio interface.
The device is found by snd_uaudio when it's connected.

It appears in /dev/sndstat:

While sndstat reports "play/rec" there seems to be no recording channel:
