When capturing sound or using iChatAV with the built-in mic of my iBook, I (or my audio-chat partner) can hear the airport traffic. It sounds like static noise that depends on the bandwith used. I think its a kind of interference with the antenna or something like that.
Does anyone have the same problem or know a solution?
BTW: I get a 5 sec audio dropout one time nearly each day. Last time it happened playing Deimos Rising (3,800,000

) and it happens in different applications. Two of my friends with 12inch PowerBooks have the same problem. I did not try if it happens with USB or firewire audio, too.
