Sound on Macbook Pro not working?

Since this morning the sound on my macbook pro has not been working? I had headphones plugged in and suddenly the sound stopped working, I didn't think anything of it and later when I'd unplugged the headphones the sound still isn't working? Why is this?

MacBook Pro, Mac OS X (10.7.2)

Have you setup the Sound in System Preferences for Internal Speakers?

Mine are set-up for my Apple Thunderbolt Display - yours should be set for Internal Speakers. It's possible that you're 'stuck' on audio out via the headphones - just make sure that System Prefs are set correctly and wiggle the headphone jack around a bit in the port until you have sound coming out of your speakers.


Good luck,


Clinton

Hello, in my case, the issue was related to the physical port switch that determines whether you have optical audio cable or headphones plugged in. I have used the headphones that come bundled with Sony Xperia Z3 and they caused the port to stuck in digital audio mode.


When I plugged and unplugged Apple headphones, then sound came back. What a shame for Apple 🙂

This problem, I have discovered, ONLY happens to me when I use a certain pair of SkullCandy (non-Apple) earphones. I tried inserting and removing them 5 or 6, (15-20 😀) times, tried poking and prodding with a toothpick (as mentioned somewhere else in this thread), but nothing worked...

...UNTIL...!

I plugged in a pair of Apple brand earphones and upon removal, my problem was solved, first try. This has worked for me twice. Somehow, I think the problem is caused by using non-Apple headphones and is solved by inserting/removing Apple headphones.


Cheers!
