Realtek ALC269VB: amixer: Capture can't 'muted'/'unmuted' even 'toggle' works

[Aapo Rantalainen]

Alsamixer shows sound-device is
Card: HDA Intel
Chip: Realtek ALC269VB

Device is working, output+input (I have read several bug reports about it).

This works:
amixer set Capture toggle

But these are not working:
amixer set Capture unmute
amixer set Capture mute

Error message is "amixer: Invalid command!" and nothing happens.

-------------------
Naive workaround:
#mute.sh
if amixer get Capture | grep off
then
 echo "muted already, do nothing"
else
 amixer set Capture toggle
fi

#unmute.sh
if amixer get Capture | grep "\[on\]"
then
 echo "unmuted already, do nothing"
else
 amixer set Capture toggle
fi

For all who's still looking for an answer:

> Use: amixer sset Capture cap
> amixer sset Capture nocap

> mute/unmute keywords are parsed only for playback
