Terrible clicking/Static Noise

[Montemanone]

I've just finished loading Hoster and all my CDG'c on my new Toshiba lap top running windows, not vista and I have a bad crackling sounds like an old 33 rpm record. I've reviewed much of the advice on the forums and my problem sounds familiar. While I will get a 3 prong to 2 prong converter, my crackling problem happens even when I run off my lap top battery, not connected to an electrical outlet.

Very cool product and didn't have this problem on my desk top. Any advice for me? Thanks so very much.
