1 MacBook Pro - Sound Output Quit - Requesting Expertise
Hello,
One day as I was busy on the computer I heard a faint pop and 'thought' I noticed a slight odor. I usually have my sound muted so didn't notice it audibly. Sometime shortly I found the 'sound out' no longer worked. Grrr, I rarely use it but, sometimes I need it.
USB sound out works, Bluetooth sound out works. I've done a fair amount of Googling and have trashed a couple pref files, played with the mini RCA jack, and a couple other efforts of 'magic wand' waving.
When a sound should play (sound effect, changed volume, etc) there is a minor, barely noticeable click/pop sound somewhere near the U, I, 8, F8 keys. Another attempt to produce that click/pop will not work till a few minutes later - then the noise can be reproduced.
The slight odor (I think) I originally noticed leads me to beleive I have a hardware issue. I'm wondering if anyone here has enough experience 'under the hood' who could give me their 2¢ on what may be the case here and maybe the difficulty level of repair?
Hardware Overview:
Model Name: MacBook Pro
Model Identifier: MacBookPro3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache: 4 MB

Thank you.

ABCellars,
Thank you. You have given me exactly what I was looking for. This is not something I can't live without, but recently decided to pursue what the possibilities are .... and thats where you came in. The toughest part is that it's my primary computer so disemboweling it will take some thought. Odds are eventually I will.
When and if I do, would I resurrect this thread or just start a fresh thread?
