I've been testing the 11.x beta on an older Lenovo G550 laptop and noticed mixerctl shows two outputs, output.master and output.master2. Unfortunately it is the second one that is actually being used but most of the mixer control apps I like to use only see /dev/mixer0 which is apparently bound to output.master (I think; my understanding of audio stuff is not great). In short, I'm only able to do volume control via mixerctl -w output.master2++ or ..-- and not with apps like rexima. Is there some way to swap the outputs?
My real preference would be to bind the Fn + Vol-/Vol+ keys to the appropriate mixerctl command strings but said keys don't appear to generate any keycodes at all currently hense the interest in using rexima or similar. For reference: $ mixerctl -a outputs.master=0,0 outputs.master2=120,120 inputs.line=0,0 inputs.line.mute=on outputs.dacsel=DAC00,DAC02 record.source=ADC01,ADC03 TIA, -B
