OSX Lion 10.7 Sound Issue Fix

Posted in: General by Steve on September 10, 2011

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.

    Thanks for the simple functional fix. I also found this frustrating, among other issues with Lion – like Preview jamming up, Firefox hanging for 30-60 seconds when resuming from sleep and Wi-Fi connections not wanting to work bacause what I thought was an additional DNS server (8.8.8.8) had become the only DNS server and probably stopped DHCP from working.

    “It Just Works[tm]” Sheesh.
