I was backing up my documents and older files on to an external hard drive and noticed that the sound has disappeared from my Macbook pro. I have OSX 10.6.8 Does anyone have any tips on what to do?
Is there any file to make the sound work
I've tried a few tricks mentioned on line, but no luck (also cant see any options in the sound for output and input devices - in system preferences)
My mic and headphones both dont work!
And you have tried pressing the "Increase Volume" key at the top right of the keyboard just next to the Power key? Does it show that your volume is turned all the way up?
