If you created a proper bug report following the steps above and you are confident it is a bug in MPlayer, not a compiler problem or broken file, you have already read the documentation and you could not find a solution, your sound drivers are OK, then you might want to subscribe to the MPlayer-advusers list and send your bug report there to get a better and faster answer.

Please be advised that if you post newbie questions or questions answered in the manual there, you will be ignored or flamed instead of getting an appropriate answer. So do not flame us and subscribe to -advusers only if you really know what you are doing and feel like being an advanced MPlayer user or developer. If you meet these criteria it should not be difficult to find out how to subscribe...
