No audio inside OSX

[jpneedham]

I'm having a problem with my Macbooks audio.

I few months ago I spilt lemonade all over my macbook. It didn't work anymore, so my insurance covered it and I got a new one, but I kept the box and more importantly the disks from the previous macbook. Today, I decided to do a full back-up & re-install. I finished that process, but found inside of Mac OSX I had no audio, so I zero'ed out data and re-installed once more using the same disks. Same thing. My guess the problem is that I'm using the disks from my broken macbook, and although technically my new one should be identical, Apple updated the driver or something. I tried to find the disks that came with my new macbook, but there no where to be seen.

So, my question to you is, what should I do? Will running a software update help?

Many thanks

Describe what you mean by "inside Mac OS X, there's no audio." Do you mean it chimes and it works under Windows?


Here's a very important thing to remember: IF ZEROING DATA MAKES A DIFFERENCE, YOU HAVE A BAD HARD DRIVE. It's not useless like repairing permissions. It causes the drive to remap bad sectors, and if that happens, your drive is failing.


Back to the issue at hand: did you spill anything in the new MacBook? Does it have a warranty? Did the audio work before the reinstall? Why did you reinstall? Why would you NOT run updates?

Defiantly try running Software Update first. If that doesn't work go into System Preferences > Sound > Output and try all the devices.

If that doesn't work you may need to reinstall using a different disk. I would talk to Apple about that one.
