Hi all.
Not sure if anyone already mentionned this.
I also have had the infamous sound-echo problem in my PowerBook 15 (rev October 2005).
But this problem completely disappears if I set to zero the volume of the internal microphone in Sound/System Preferences.
I've been listening to music this morning, from 9AM to 2 PM, and didn't get any echo prob. I used to have about one every ten minutes before.
That's it. May be it's only me, but it sure fixed my musical life.
