    Hey all, I was watching a movie on the bus using my headphones earlier today, and whe I got home just now, the internal speakers aren't working. There is a red light coming from the headphone port.. and the volume can not be adjusted.. is there a software fix, or do I have to take this thing to the genius bar?
    ETA: I restarted the computer, still no dice...

    ETA 2: never mind, I fixed it...

    The red light in the headphone/microphone port signifies that Digital in/output is being used, as opposed to analog.

    The most common fix: Insert headphones into the port, then yank 'em out. Repeat until the light goes away. It's just something that's stuck inside. I have friends with MBP's that had this issue, I did too once.

    fix to internal speakers not working

    Hi, I had the same issue and the port had a small red light coming out of it. It is stuck in digital audio mode, and likely just needs to be cleaned. I stuck a tooth pick in there gently and a tiny bit of lint came out. It instantly worked as soon as I plugged and unplugged my headphones. It now recognizes that nothing is plugged in and the internal speakers work again!
