Quoted from JCrusher:Does Anyone with the cleland mod get random loud clips/beeps? Seems pretty random but sometimes after a game or between balls there is a loud clipping sound. I'm on 1.02, not sure if this normal or some issues with mine. I searched on the subject and couldn't find anything.
I have not noticed it on mine. I’m running 1.02 as well. I’d try reflashing the SD card or try a different card completely.
