I use iSyncr to sync my iTunes library daily with my phone. The process works perfectly with Poweramp and I have no problem with Poweramp getting the new playlists and files once they are synced. Recently iTunes has moved to the M4A format for many of the podcasts I subscribe to. Unfortuantely these files are only able to be played by Poweramp from the beginning. Once I try to fast forward, rewind, or pause the song, the file cannot be restarted by Poweramp. The application then goes to the next track in the playlist or tries to play the file from the beginning. If I right click the Podcast in iTunes and use the "Convert to AAC Format" feature, which still leaves the M4A extension, I am able to play/pause/fast forward/rewind the file without a problem in Poweramp. I believe the only difference between these two files is that the newly converted M4A does not have the "Chaptering" features that the original file has. Does Poweramp support M4A chaptering? Will this be fixed in the future?
