Customer Question
Hi, the audio system...

Hi, the audio system in my macbook air is not working. THere are no output or input devices found in system preferences. I have tried rebooting; deleting the audio files from the preferences folder on the hardrive; and clearing the PRAM (although I'm not sure I did that correctly) and it still does not work

Technician's Assistant: Can you still find your audio files in the Trash bin? Have you set up any backup software (e.g. Time Machine)?

I emptied the trash and rebooted after deleting those files. I have an external harddrive which I use as a back up drive

Technician's Assistant: How long ago was your audio files deleted?

Approximately 5 minutes

Technician's Assistant: Anything else you want the Mac Expert to know before I connect you?

I think thats everythign

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
