Audacity Users, A Minute Of Your Time, Please?

I’m using the service through W 11 to convert some music cassettes to mp3, and have a question.

In audio set up, the field that shows in the center for the right and left channels isn’t registering that it “hears” any sounds, but at the top, which shows right and left and left channels, I can see that it is showing sounds.

The area in question usually shows a vertical line moving from left to right, it just doesn’t reflect that the volume is too loud or soft. It just moves left to right. Is there a fix for this I am missing? The input record setting I use is USB P in P audio device.

Thanks for your assistance.

Bill
