Mavericks: No sound after sleep I have installed a fresh version of mavericks on a MacBook Pro 13". After the computer wakes up from sleep, I have no sound - neither in earphones nor in speaker.

The problems has been reported by many users in the Apple support community.

Is there any solution besides rebooting?
I could fix the problem by reloading the kernel extension for audio with these command:

sudo kextunload /System/Library/Extensions/AppleHDA.kext
sudo kextload /System/Library/Extensions/AppleHDA.kext
