On the touch panel, there are two Course Capture indicators. One is for the audio levels and the other is if recording is in progress. The audio level detects both program (from your computer) and microphone audio. To check the audio from the microphone on its own, please make sure you mute your computer from the computer directly.
The touch panel design is being upgraded through Summer and Fall 2023, so here are two screenshots of a typical touch panel with highlights on where you can find the two Course Capture indicators.
