After 10.8 update no sound
I updated to 10.8 last night and today noticed that the sound no longer works. the buttons on the keyboard do nothing and I cannot change the setting from the icon. Under system Preferences all the options are greyed out under sound and I am using an admin account. Has anyone else experienced the same issue?
Running:
2.66 GHz Intel Core 2 Duo
8GB RAM DDR3
Early 2009
Thanks for any help you can provide
