/dev/sound is already linked to /dev/sound0, /dev/audio0 -- to
/dev/audio and /dev/mixer0 -- to /dev/mixer.

The following

   mixerctl -w inputs.dac10=N,M

command changes volume in left (N) and right (M) channel.

Catting files to /dev/audio and normal ogg123, mp123 programs work fine.

Catting to /dev/audio1 doesn't work.

After linking /dev/mixer to /dev/mixer1, aumix seems to work normally,
i.e. it shows two volumns with volume and pcm and allows to move box to
the left and right but audio volume is actually not changed.

P.S.
Is there any explanation for that criptic mixerctl -av output?
How I can know that inputs.dac10 is responsible for volume?
