If the Mic is on and the speakers are set to max, the mic will pick up sounds from the room, put them out through the speakers where the mic will pick them up and put them out through the speakers. Forever.
If you turn the volume down, does the whistle go away?
If the mic is turned off, does the whistle go away?

Hello,
I have an iMac Flat Panel 17" (G4 - 1.25 Ghz - OSX 10.4.5).
In the last days a strange problem appeared:
when the integrated microphone is set on, and the
output level is at the max, even if the computer is
totally idle the right speaker whistles very loud.
Is it normal ?
Thanks
