I have no sound :-(

[ProDigit]

hello,

I've got no sound.
It probably isn't a bs-player error, but it all happened with installing WINXP SP2

Most of my sound seems to work, only WMP, and bsplayer don't even notice there to be no sound.

I removed the MP3 audio decoder .DLL file, in Windows/system; and WMP found out there to be no codec, so it requested to reinstall the codec.

I did, but still, no sound.

I tried some codec-packs, I tried some players (DIVX-playa works fine with the sound, though the problem is, that it doesnt play all formats(MKV, XVID, etc.)

what do I do now?
It's not a hardware issue, because I can hear sound, when I'm testing my speakerconfig; midi, mic, and CD.
Also, my DVD player gives sound..

What should I trie next? :?

Maybe an AC3 decoder ?
And to change in options->preferences->audio your default output device to DIrectSound for example.
