My internal speakers on my MacBook have decided they don't want to work. I've checked all settings and that's all fine, and I can't see a problem with the soundcard as I can listen to sound perfectly fine with external speakers/headphones.

When I try to adjust the volume with no headphones/external speakers plugged in I get a little symbol saying I can't, (circle with a line through it, sort of like-> (/) ) However it says that the volume is at it's highest - yet there is no sound at all.

Another odd point to note is that there is a red light being emited from the headphne jack.

Any ideas at all? It's driving me insane.

Do you have Applecare? I would try bringing it to your closest Apple store, if that is an option.

This is a software setting, I'm not sure how to fix it but have read posts on it before.
