I have purchased (just now) the M20d for the primary purpose of recording Multi tracks and am experimenting with the same now. therefor I may be wrong in my suggestion, but you can try. Did you have the XLR cables plugged in on the respective channels when you tried to play back (in the same channels as you recorded) ? (the system seems to have a Hardware switch below the Mic jacks to enable the respective channel). So it may help to enable the channel before playing the tracks. Though the logic does not seem to be good, please try this and share your experience.

This is kind of late however, I have sorted out my Playback issue since Line6 released the new Upgrade. It now works very well with no problems at all. It took me a little time to sort it out but it's GREAT!!!
