Was trying to play an SN ep on RP, but cant hear a damn thing with it...but I can listen to music, so its not just my sound on mute on my comp...and RP sound doesnt seem to be muted either... any ideas on how to fix it?

It's usually a codec problem. Or maybe the player is not compatible with the format.

whats codec? I've played the same files on it before and they seemed to work...
