Only allowable value for above field is ADC01. See below:

$ mixerctl -av
outputs.master=254,254 volume delta=2
outputs.master.mute=off  [ off on ]
outputs.master2=254,254 volume delta=2
outputs.master2.mute=off  [ off on ]
outputs.master3=254,254 volume delta=2
outputs.master3.mute=off  [ off on ]
record.mic=0,0 volume delta=51
inputs.reclvl=0,0 volume delta=17
record.mic2=0,0 volume delta=256
record.mic2.mute=off  [ off on ]
inputs.beep=255,255 volume delta=64
outputs.dacsel=DAC00  { DAC00 }
record.source=ADC01  { ADC01 }

If I still try, it says "Bad set value"

Only time I get some weak noise from recorded file is when I set
record.mic to 189,189 or above. For all other combinations I get complete
silence. This noise, too, has nothing to do with whether mic is even
connected or not.
