Audio not working on Macbook, tried the ol' audio jack in/out fix to no avail

[tylermiller805]

Here's what happened.

Come home, open the lid on my macbook, play music, no audio comes out, go to MacRumors.

Thanks to you wonderful Macxperts I have tried the following to no avail.

- Volume is at max
- System Prefs>Sound>External Speakers>Volume Max>Not Muted
- No red light coming from the headphone jack
- Tried inserting and removing headphones, no sound in speakers or headphones
- Restarted computer while holding down ⌘ + OPT + P + R , no sound made
- A very very faint feedback, like when you plug an electric guitar in to an amp, can be heard when the first sound (the mac start up chime) is supposed to play on restart
- USB headphones work



Mucho Thanko if anyone can help

I'm afraid you've got your options covered. You'll have to have someone take a look at it.
