When i use my webcam the other person hears a loud hissing. It doesn't happen all the time. You can connect and it'll work fine for a lenght of time then starts hissing. When you cancel the call and start again it works fine for a while then the same again. I don't have the hissing at my end though. I've tried it on msn messanger and skype, I've even returned the webcan and got a replacement but still the same !! Any ideas ???
