Anyone know a way to fingerprint the audio input from an HDMI to USB capture card? I'm experimenting with a Raspberry Pi 4 and would like the capture card to act as the microphone input. I could certainly use a USB sound card or USB microphone as an alternative, but would prefer the HDMI to USB capture card if addressable as it's already being used for video input in this project.
The audio can be preview in my setup on the Pi via FFMPEG - ffplay -f pulse -i default
