I think I found the issue: https://nxr.netbsd.org/xref/src/sys/dev/hdaudio/=
masterctl is coming NULL, this is why mixerctl is not able to find outputs.=
There are 3 possibilites for this happening:
1) or the if in line 2827 is false
2) or the for's condition is false because sc->sc_nctls is 0
3) the if in line 2823 is false
Well, at the end I believe is something caused by pins misconfiguration. An=
yway, what is that comment in line 2821 about TODO softvol? Can this missin=
g softvol be the cause of this problem?

do mixerctl -w outputs.master++ it goes from 0 to 128 only and -- from 128 =
to 0. There is no other option in this 0-128 range =3D/
