MacBook Pro - Temporarily Lost Sound

[John Doe 57]

I temporarily lost all sound on my MacBook Pro. I hooked it up to my television and had good sound. Then I unplugged it from the TV and lost all sound. I couldn't get sound through the speakers on my computer, television, or iPod headphones.

I went online and searched for similar problems. I was amazed at how many people had the same problem. Many of these people were forced to send their computers to Apple to have it fixed.

I found this:

The question I have is should I be worried?

Have you performed a PRAM and SMC reset?

I had this problem after unplugging headphones just last week.

I went to the Sound preference pane and under output made sure that "Internal Speakers - Built-in Output" was selected and sound immediately started to play. I hope it is that easy of a fix for you.

It is very unlikely that the simple switching of outputs caused actual damage to the sound card that Apple would have to fix. Make sure everything is right in sound settings, plug in some speakers/headphones etc. As a last resort, I would boot up into Windows to ensure it actually is a software problem.

This happens to me sometimes. What's happening is the optical output is being turned on and not being turned off when you unplug the headphones/cable.

The best way I've found to fix it is to repeatedly plug-in some headphones (I always use my iPod ones - they're expendable) until it goes away. I think the switch is on the left, so aim it that way.

Should I? I mean everything is fine as of now. Perhaps I will boot into Windows later to make sure sound is working there as well as Techhie suggested.

No need if the sound has returned!

Strange hoe everyone suggested how to fix it when it was already fixed. That is why I said 'Temporarily.' Either way, thank you everybody!

This is what I was thinking to suggest to try.
