 I think I found the issue: https://nxr.netbsd.org/xref/src/sys/dev/hdaudio/=
 hdafg.c#masterctl
 
 masterctl is coming NULL, this is why mixerctl is not able to find outputs.=
 * properties.
 
 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?
 
 Thanks.=20

 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/
