So, I made the mistake of upgrading my main computer to MacOS Sequoia (15.1), thinking everything should be good by now. But of course I was immediately hit with an issue. When I go into Mimo (6.8.3), my main microphone is not working. It is there as a choice, but there is no sound coming through. In Final Cut Pro, QT, Screenflow, the mic is working fine, just not in Mimo.
I switched to my external webcam mic, and that worked fine, as did using my iPhone as a mic.
However, I did discover that after a bit of time recording, my external webcam mic went from working, to making a loud buzzing noise. Switching to a different device and back, in Mimo, fixes that. But I am not sure what to do next…
