No sound out of left and right internal speaker?
I have the 2006 Core 2 Duo version of the MacBook (A1181), and my problem is I'm not getting any sound from the internal left and right speakers. I get sound from the middle speaker, but not the left or the right one. I have opened it up, and it seems like all speakers are plugged in correctly. I don't have the "red glow" problem (stuck on optical). What could be the problem?
