MBP sound issue.

[whitehorse84]

I have a macbook pro 2.33ghz and yesterday I was watching some episodes of curb your enthusiasm via headphones and this morning i grabbed my computer and started some work this morning. I started it up and go tthe usual apple "start up sound" but now there's no sound on my computer.

When i click the keyboard volume buttons the volume symbol is greyed out (yet the white bars are all there).. and the volume status icon in the toolbar is greyed out as well.

I tried a restart.. anyone know how to fix this?

also, headphones still work.

I have a red light beaming out of the headphones jack as well.

odd, so now it works.. i still have the red light inside of the headpones jack that for the life of me cannot remember if it was on before or not though.

I read this thread:

and tried to play with the switch myself using a straw and now the sound works, i just don't remember that light being on or off.

It sounds like the switch was stuck, and in the 2nd post when you put the headphones in again, that's where it fixed it... but the main thing is that it works now.
Not bad, OP at 12:11, headphone status 12:19, resolved by 12:31

true!

the only odd thing is the red optical light is still on in the headphone jack yet my on board speakers are working just fine.

hmmmm

You could try the plugging in and unplugging jack a few times, see if this resets it, or using a toothpick.
It just happens from time to time that when uplugging in many MBPs, where it doesn't switch itself off, but as long as your speakers are working, I wouldn't worry about it, esp if it can be fixed so easily so quickly.
If you were under warranty still, I'd have suggested taking it to Apple, but seeing as you're way out, I'd just hope that it all stays good from now on.
