Mic problem

In the past Ive used the same method for having the mic detect what Im playing and it worked but suddenly it doesnt want to work anymore. Almost every note is going red, Ive got the volume as low as it can go so I can still hear the music and Ive got the piano at a good volume too so I dont know what happened.
