If you're using an M-Audio MobilePre USB audio interface to record audio in GarageBand, your recordings may sound clipped and distorted—even if the incoming level is set appropriately.
This issue occurs if you're using the MobilePre USB driver version 1.5.7fl or earlier, and set the latency to Low in its preferences. You can resolve the issue by installing the 1.6 or higher version of the driver from the M-Audio website.
