pcm3: <ATI R6xx (HDMI)> (play) default
pcm4: <ATI R6xx (HDMI)> (play)
pcm5: <Realtek ALCS1200A (Rear Analog 5.1/2.0)> (play/rec)
pcm6: <Realtek ALCS1200A (Front Analog)> (play/rec)
pcm7: <Realtek ALCS1200A (Rear Digital)> (play)
No devices installed from userspace.


os: freebsd 12.2
mobo: b550m mATX
alsamixer shows only 1 pcm device which is unmuted already. mpv uses oss for audio.

Try switching to one of the other HDMI outputs. Each output corresponds to a specific connector, and it's not always clear which one is the right one where your monitor is connected to.

had already tried changing hw.snd.default_unit from 0 to 7 before posting it. left it at pcm3 because in linux it was pcm3 that worked. shall try again.
