No Audio From WMP10

[kmf]

All of the sudden I am not getting any audio when I try to watch something with WMP10.

I tried removing it and then re-installing, but that did not help.

I know the files are good as I have watched some of them before with WMP10 and all of them have audio when using a different player.

Any advice?

maybe you need a particular codec to play it with

an audio or video codec you may need
