MacBook Internal Microphone Disappearing
Every now and then, my internal microphone disappears from the System Preferences Sound panel, under the Input tab (screenshot), leaving me unable to select it for usage. It also doesn't appear when I `option+click` the sound icon on the upper system bar, near the clock. Rebooting usually helps, as well as resetting SMC and PRAM/NVRAM.
Apparently whenever I connect an external audio device (AirPods or a wired external headset), eventually the internal input device goes missing.
I'd love to troubleshoot this myself, but I have no clue what to look for on the Console (side note: that thing is a nightmare nowadays of so much logging that's going on there).
Took it to my local authorized Apple service rep, to no avail.
PS: there's someone else out there with the exact same issue and setup than mine: https://apple.stackexchange.com/questions/357513/mac-doesnt-recognize-internal-microphone
