Something really strange is happening on my iBook. I heard weird buzzing noises when recording sounds with my iBook, about every 3 seconds. Turns out that only happens when Airport is turned on. Now I tried it again, with "Play thru" turned on in Audiocorder. Get this: the buzz every 3 seconds is always there, but when data flows (web page, download etc), a constant buzzing is audible. Seems like the airport signals are picked up in the mic circuity somehow.
This sounds like a hardware issue, but could it still be a software problem?

I'd guess this is a hardware issue. The headphone circuitry is certainly vulnerable to picking up stray signals; mine gets interference from the video hardware so that I get interactive buzzes!

I'd imagine the mic circuits are also susceptible, and both the AirPort antenna and the mic are housed in the screen...

It's a known issue... I guess this is the problem described here. Hopefully this is as software issue which will be fixed.
