I tried setting inputs.mix_source to each setting above. Here are the results
# mixerctl inputs.mix_source=dac-0:1 no sound
inputs.mix_source: -> dac-0:1
# mixerctl inputs.mix_source=mic yes, very quiet
inputs.mix_source: -> mic
# mixerctl inputs.mix_source=line-in yes, very loud
inputs.mix_source: -> line-in
# mixerctl inputs.mix_source=mic2 no sound
inputs.mix_source: -> mic2
# mixerctl inputs.mix_source=dac-6:7 no sound
inputs.mix_source: -> dac-6:7
Their is nothing plugged into the line-in. Eventually, I need the line-in to
work.
Thanks for any help!
