Reading mic / camera switch states

Framework Laptop 13 Linux

I’m looking for a way to read if the hardware switch of the microphone and camera are active / inactive. Is this maybe exposed somewhere in /sys/*?

It’s a hardware disconnect. It is literally electrically disconnected from the mainboard.

It’s attached by USB and appears/disappears from lsusb, though it might be easier to detect the presence or absence of an entry in /dev/video0.

Yeah true, that counts for the webcam, which indeed disappears, but the mic isn’t connected through USB. So it’s hard to differentiate if the mic is still “accessible”, or that wireplumber points to the aux mic possibilities of the audio card.
