Hmm, doesn't this still select a fixed card?

E.g.

~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

... you'd get the same with "amixer -c 0" gets us.

Select a card using its name, such as "sofsoundwire", instead of selecting it using numbers

aplay -l | head -2 | tail -1 | awk '{print $3}'

sofsoundwire

Command shall be like: amixer -c "sofsoundwire" cget name='Dmic0 Capture Switch'

@harajend But "head -2 | tail -1" will always pick the first card, so this is same as passing "amixer -c 0", right?

awk is a "big boy" and can select lines itself. It's shorter AND more readable:

   switch=$(aplay -l |  awk 'NR == 2 {print $3}')

amixer -c 0 looks even better? I'm only simplifying code but I don't know if it is correct.

Yes, On functionality front both are same. Here I thought to pass "name/identifier" instead of "index number"
