So after upgrading my MacBook to Lion, I noticed that every once in a while, my sound would go away. I wouldn’t be able to listen to anything using the laptop speakers. I could plug in headphones, but if I wanted to play music for the kids, I wouldn’t be able to. I’ve been searching around for an answer and finally found one in the Apple forums.
The fix that worked for me was opening a Terminal window and running this command:
sudo killall coreaudiod
This will stop the sound and then restart it after a couple of seconds. This re-enabled the sound on the laptop.
Hope this helps anyone else because I was very frustrated after the upgrade.
