Audio issues


New Member
Yesterday all was fine in the world. Today ... not so good :(

OBS will now not recognise an external mic despite it working well previously.

The mic is a 3.5mm lapel mic plugged directly into the jack on a 2016 15" MBP. I have two of the same mic and neither is working. The mic shows up in input in system preferences but not in OBS's drop down when adding a new audio input.

I have tried restarting Mac, restarting OBS, reinstall (library files also deleted), reset NVRAM, disabling and apply all audio and then re-enable...

I'd love to get it working again can anybody help with any suggestions before I take to the computer with a hammer in a rage?
