Sound Looping

[ClanMatch.com]

Greetings,

I successfuly set up a shoutcast server today.

I have the settings as stated in other posts as "What You Hear" selected as well as Mic enabled on my XPpro system.
My problem is every sound is looped repeatedly untill it fades out to nothing. Usually about 5 times. Is there a way to get rid of that?
Is it because I have my winamp volume on?
I am at a loss and would appreciate any help someone may give.

Regards
