I think im experiencing the same problem. media worked fine pre dropbox but every deck i now import I have no sound when i review the cards. the media files work when played in another program (opened in itunes) but I cant for the life of me figure out why they wont play in anki!? could this have something to do with dropbox? any thoughts or suggestions would be much appreciated. I have pretty much stopped studying for a few days now trying to figure out this problem but just giving up after a while cause i cant.
