I'm running Audio Cleaning Lab on a Dell Inspiron laptop using Windows 10. When recording a music stream the graphic display and audio seem to be in sync, but when I stop recording the graphic is redisplayed and when I play it back, the audio signal is no longer in sync. Typically, the audio comes to and end but the graphic image is some way before the end.

I have reinstalled the software and the problem persists.

Any ideas?
