I plugged in my headphones to my computer earlier and when I removed them my computer wont play sound anymore. The red light in the port is still on. Any body have suggestions
1. Remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.
2. Reset PRAM. http://support.apple.com/kb/PH4405
3. Reset SMC. http://support.apple.com/kb/HT3964

"Resetting SMC on portables with a battery you should not remove on your own".
