Powerbook speakers going crazy

[thickcmhs]

I have a 15" Powerbook G4 and recently my internal speakers have been acting weird. Randomly my speakers will stop working and constantly put out a fuzzing noise that sounds like a t.v. that is on a blank channel. This happens either right when I turn on my Powerbook or later while I am using it. i don't even have to be using an application that invovles sound for it to happen. Also, if I mute the sound on the Powerbook it does not go away. The only thing that works is to plug headphones into it and then mute the sound. However, when this is not happening, the speakers work perfectly. I have tried messing with the sound controls and even re-installing mac osx tiger on the powerbook but it still has the same problem. Does anyone have any ideas on what I could do to fix this? Also, is it a problem with the speakers or something else?

When you plug in headphones, does this funny sound come out the headphones too, or is it limited to the speakers?

No the sound works fine when I plug in the headphones or external speakers.

If you're under warranty, take it in to be repaired. I suppose take it in either way, actually... I just hope you're under warranty .

If it were the built-in sound card chip, I think the distortion would come through the headphones too. Could be static interference from another component close to one of the speakers. Which model of PowerBook is it?

Seems lika a hardware defect. Call Apple if you still got warranty.

I have the Powerbook 5,8 model. I'm under the 3 year protection plan so I think I will call Apple today and send it in. Thanks.

whats first in line in the audio path? The speakers, or the headphone jack?

possible bad connection btw cound card and speakers.....but if the headphone jack is after the speakers...then im lost....

Warrenty = good.
