[resolved v142] alsamixer fails to load

[Sciamano]

Hello,
I seem not to be able to run alsamixer on any of my devices with dietpi.
I always receive the error:

Code: Select all

cannot open mixer: Invalid argument

This is really annoying, and to change my audio settings I had to fiddle with amixer, with the result that what would have been a 2 clicks task in alsamixer took me 15 minutes from the cli.

Will alsamixer ever work again in dietpi?

Alsamixer is fixed in DietPi v142 update.

In the mean time, you can fix this now, by removing the device line from ctl.!default {} in /etc/asound.conf

eg:

Code: Select all

pcm.!default {
    type hw
    card $SOUNDCARD_TARGET_CARD
    device $SOUNDCARD_TARGET_DEVICE
}
ctl.!default {
    type hw
    card $SOUNDCARD_TARGET_CARD
    #device $SOUNDCARD_TARGET_CARD # REMOVE THIS LINE
}

I've just tried this on my OPi PC, and it worked!
THANK YOU! THANK YOU! THANK YOU!
