I upgraded my Mac to 10.8 yesterday when it was released and the update has caused my MacBook's volume keys to become non-functional, although I can still change volume through the icon in the menu bar or through system preferences. When I press the keys to change the volume, the transparent volume icon appears on the screen with a circle-slash icon at bottom center. Does anyone know how to make the keys functional again?

The "circle-slash" means that it's muted. Do you have a mute key on your keyboard that you can press to toggle mute, or can you manually unmute it in settings?

It's not muted. When I press the mute key, the effect is almost the same as with the volume adjustment keys, the only difference being that the transparent speaker icon has a slash through it, indicating mute (although the key does not mute or unmute the sound). That mute icon has the same white circle-slash at bottom center as the volume adjustment icon. – Gregory – 2012-07-26T19:24:42.847

The issue resolved itself after I rebooted.

Which audio adapter is selected in your system preferences, or when you hold
Optionand press the volume icon in the menubar? – slhck – 2012-07-26T18:19:09.513Not sure what you mean by "audio adapter". The output device is set correctly to internal speakers. – Gregory – 2012-07-26T19:21:44.770

For future reference, it's likely that restarting just
coreaudiodinstead of your Mac might help. Trysudo killall coreaudiod– Soumya – 2014-04-27T06:57:49.803
