Can someone help me figure out why I can't get any sound in the Winamp Media Player?

I have the volume turned up high in the player itself and on my laptop so that’s not the problem.

For both music and video, there’s absolutely no sound whatsoever.

For video, the picture works great, just no audio.

I don’t think it’s a file format issue either, because the files play just fine with sound in different media players I’ve tried.

So I’m assuming it has to be a setting in Winamp itself I’m not seeing? Can someone walk me through this problem? Thanks.
