Sound Problems,
 

I can't get sound to work, I ran alsaconf, then I opened up a mp3 file in totem It says

This is an audio-only file, and there is no audio output available.

It also says something similar in beep-media-player

sound has never worked, I tried searching on google but I think I'm not using the right keywords

beep-media-player's error

Couldn't open audio.

Please check that:
1. You have the correct output plugin selected.
2. No other programs is blocking the soundcard.
3. Your soundcard is configured properly.

I had smth similar, but with xmms. And I had the same error-window many times, but not now. Actually I was troubled about "duplex sound"... but have a look at it, 'keefaz' gave a link to alsa site, there's some info about alsa...
