First I would suggest it sounds like your computer is stuck on Digital Output (because of the red light), as if there is a dongle or digital output connected to the computer. Which would make the computer think to disable the internal speakers.

I was doing a little more research for someone else having the same problem. I came across this thread at apple's support site. It suggests using a toothpick to disengage the audio jack.

Good Luck.

--------------------------------------

If that doesn't help, let's confirm some settngs.

Go to Applications / Utilities / Audio Midi Setup

Confirm that Default Input, Output, System Output are all set to "Built-In Output"
Under "Properties for" set to "Built-In Output".
The "Audio Output" box in the bottom right, the following should be selected:
Source: Internal Speakers
Format: 44100.0 Hz / 2ch-24bit

-----------------------------------

Next go to System Preferences / Sound and confirm the following settings (if you can):
Under Output:
Internal Speakers should be selected as the Built-In Output, if not let me know what it does have in the dialogue box
Output Volume is not Muted in the check box at the bottom.

------------------------------------

If above suggestions yield no results, let me know and we'll go from there.

Thanks. I used a toothpick equivalent to disengage the headphone jack and apparently it is back in working order. I guess there was dirt (imagine that I live on a ranch) that kept it jammed in that position.

BTW, I am from Middletown, OH and went to UC for a semester when I was teaching in Mariemont...

Thanks again.

Glad I could help! Middletown huh? I drive down through there everyday. I live near Troy, but work in Cincinnati. Small world.

Thanks for the Accept, please let me know if I can help you with anything else!
