>Description:
I have a issue with my audio mixer for long time now (may be 5 years or so now), the audio volume changes only if I change "inputs.dac" and if I change "outputs.master" nothing changes. I think the "inputs.dac" and "outputs.master" are switched some how. For me personally the mixer name is not important, but several applications changing the outputs.master volume and it is very annoying, f.e. if I use pavucontrol to change the volume, then it changes "outputs.master" but this has no impact on the actual audio volume.

$ mixerctl -a
inputs.dac=156,156
outputs.master=198,198
inputs.reclvl=88,88
inputs.reclvl.mute=on
outputs.master2=184,184
outputs.master2.mute=off
outputs.master3=0,0
outputs.master3.mute=off
outputs.master4=0,0
outputs.master4.mute=off
outputs.master5=0,0
outputs.master5.mute=off
outputs.master6=252,252
outputs.master7=252,252
outputs.master8=0,0
outputs.master8.mute=off
outputs.master9=0,0
outputs.master9.mute=off
outputs.dacsel=DAC00,DIG02,DIG03
record.source=ADC01
outputs.dac0=255,0
inputs.mic0=255,0

What I see here, is that "inputs.dac" is the first entry, and in kernel the "outputs.master" mixer has the mixer id 0. Is it possible, that the names switches some how it it comes to userland?
>How-To-Repeat:
Start a NetBSD 7.99.54 on a amd64 machine, similar to this, play audio with MPlayer and change "outputs.master" with "mixerctl", then the volume will not change (but should).
