Audio stutters while browsing

[deep'n'dark]

Hi!

I am listeing to the winamp radio channels via this site but my sound is glitching or stuttering when I browse whatever site at the same time. I have searched google and tried many things but no luck so far. I updated to the latest adobe flash, tried another browsers but it didn't help. Before i start sepcualting too much I'd like to ask your help and advice how to solve this problem and what is the reason for this.

Thanks!
