Although #187 had users input a device-specific amixer_card_num as a parameter, that card number can change when the computer is restarted. Hence, this PR has the code programmatically determine it instead.
Testing procedure
[x] Pull this code and re-build.
[x] Restart the computer with the USB mic plugged in.
[x] Run setfacl -m u:ada:rw /dev/snd/*, then wait ~5s.
[x] Start the code, verify it reads the USB mic (e.g., by ensuring e-stop clicks are registered).
[x] Verify unplugs are registered.
[x] Restart the computer with the USB mic unplugged.
[x] Plug in the USB mic.
[x] Run setfacl -m u:ada:rw /dev/snd/*, then wait ~5s.
[x] Start the code, verify it reads the USB mic (e.g., by ensuring e-stop clicks are registered).
[x] Verify unplugs are registered.
