Hi Guys,
I own a version 1 MacBook Air. The sound has vanished, when I go to preferences the mute check box is ticked and grayed out so that i cannot un-mute. I have tried inserting ear phones and restarting my Mac to solve the issue as recommended but this dose not solve the problem.
in preferences sound if i connect ear phones they are not recognised in the output box.
Can anyone help me please ?
Best Regards,
Nick
