I've had this problem once before with static in the sound and I re-seated the ribbon cables and that seem to have fixed the problem. Now that trick don't seem to work. How can I fix this once and for all?

I don't have a pinsound or any other card than the stock audio board. There's not a USB port on there is there?

It seems that the music is fine if I pull the ribbon cable, but the call outs and sound effects are gone. Connect the ribbon cable back up and the static comes back.

I found this information on PinWiki and I'm going to give it a try.

6.29.5.6 Popping, Scratchy Sound, Very Hot
LM1875 Heat Sink, or Shorted Speakers

Sometimes, the tantalum/ceramic caps in the amp circuit fail too. This can result in too much AC "ripple" feeding the amp as well as DC output to the speakers, which they do not like. The following components are all suspect...

C20 (10µF, 20V tantalum)
C46 and C47 (both 1µF, 35V tantalum)
C22 (22µF, 35v electrolytic)
C23 (.22µF, 10V, ceramic)

So far, since I took the board out, it has been working great. When it was out, I did push down on the chips that was in a socket and I could hear them resetting from the cracking and popping that was going on

Still have parts coming in, but I'm not ready to replace anything until there is actually a problem that is persistence.

Well, board started acting up again. I replaced 3 47µF capacitors in the sound circuit; C15, C36, and C38. Lets see if will act up again.
