Re: kern/57444: no sound through Realtec ALC269

[Bruno Melo <bmelo%protonmail.com@localhost>]

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. Anyway, what is that comment in line 2821 about TODO softvol? Can this missing softvol be the cause of this problem?

Thanks.
