OK...so it seems that if I uncheck 'Mute' then the audio is captured when I record screen. Makes sense! Is that all?Looks like this...see attached photo.
I seem to remember previously being able to capture the audio when recording the screen without it being audible to me during the recording. This would be optimal, so I can make my recordings while doing other things. Please let me know if there is an option for this. Thx!
