What I feel unused to is the need to set ffmpeg code both Audio and
Video input format and input device respectively.
A couple of syntax examples for audio found:
ffmpeg \
-f alsa -ac 2 -i hw:CARD=HDMI,DEV=0
https://trac.ffmpeg.org/wiki/Capture/V4L2_ALSA
-f pulse -ac 2 -i default
https://dev.to/ethand91/how-to-record-webcam-video-and-audio-using-ffmpeg-419c
