I have this same problem, but it is only with one file. I have dozens of other files that work fine. I'm not synching with video or anything, just a simple music demo recording I am bouncing to my phone. I tried moving all the regions a couple seconds later in time but it still starts at the same exact place, and the cursor just keeps landing at the same exact place as before, a second or two into the recording after the bounce if that is a clue. It plays just fine when not bounced. None of the answers here really address the CAUSE of the problem, they are just work arounds, most of which I do not understand. Any new ideas?
