I'm assuming you're talking about audio coming from the mic or the
line-in, right?

see mixerctl(1).

for audio from the line-in, do something like this:

greke:~% mixerctl -a | grep line      
inputs.line=7,7
inputs.line.mute=on
greke:~% mixerctl inputs.line=255 inputs.line.mute=off
inputs.line: 7,7 -> 255,255
inputs.line.mute: on -> off
greke:~% 

and of course check that output is set as appropriate

greke:~% mixerctl outputs.master outputs.master.mute
outputs.master=191,191
outputs.master.mute=off
greke:~% 

note, the mixer device names above might not be exactly the same
as what your device has.  it is similar for audio from the mic input,
although you may need to also turn on the mic preamp (usually
mixerctl inputs.mic.preamp=on), although this is not always desired.
