wy my playback file is fast forwarded while im editing it?

sometime it is happen, when i add some effect and try to listen to it, it just sound fast forwarded, and i have to pause and play for a while until it sounds normal again, but it will happen again and again, and im newbie using this app, im using version 3.1.3

Perhaps this is a hardware issue. I would try using a different output device. :smiley:
