Are you talking about the startup chime, or a sound that's constant, or something that's intermittent?

Hello,
Thank you for the reply. There is no startup chime at all through the speaker, whenever there is supposed to be an output the sound is very faint and 99% static. The external sound out does work with a pair of powered speakers though, and I have even hooked up a small speaker to the leads from the MB and get the same thing.

the same thing.

Lost,

When you say "you get the same thing; do you mean good sound out, or do you mean static?

hello,

when I hooked up another speaker to the output pins on the MB I got the same static noise as the internal speaker itself. I just wanted to make sure that the cause was not the internal speaker itself.

Well, it couldn't be anything

Well, it couldn't be anything other than a bad component on the motherboard, so you might as well just live with it or get a new motherboard. External speakers don't necessarily have to be powered. You can get a pair of dinky unpowered speakers if you don't want the hassle of batteries or a wall wart powersupply. You could also simply cut off a 1/8" plug line (from cheap speakers or headphones), run it from the external jack back into the case and wire it to the internal speaker. Would be all the same. (You know, you're not an official electronics tinkerer unless you've got at least one pack-rat box full of plug wires that you cut off and saved before you threw that appliance, headphone, etc. away).

Consider yourself fortunate. I've had G3's and a G4 which lost their external audio jack output. That's much more of a bummer. I had to buy a USB iMic to run my external speakers.
