MacBook Pro - Sound Output Quit - Requesting Expertise
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?
