I am experiencing similar playback issues. I usually play long track loops continuously. With PlayerPro, I've recently seen 1) audio reported to be playing when it actually isn't, and 2) single short tracks being reported to play for many hours at a time, when in fact they are "stuck" and not emitting any audio. This seems to have gotten much worse in the past month or so.
