Help w/ Audio

[themaniac84]

I was able to get my system up and running everything worked out of box except the sound. I was able to find a post on how to get my sound to work off my GA-G33M-DS2R mobo but I'm not quite sure what to do or how to find System/Library/Extensions to copy the kexts to. It, the post says to do the following:

1) To get audio to work I need to copy the tho kexts into System/Library/Extensions
2) Remove the azalia audio kexts
3) sudo chmod -R 775 /System /Library/Extensions/*
4) sudo chown -R root.wheel /System/Library/Extensions/*
5) remove the Extensions.kextcache

Say I should get stereo out, mic, line in and spdif out.

This sounds great but I have no idea about going into System/Library/Entensions.

Could someone who knows what they are talking about give me the skinny on how to do this?

i would appreciate it a lot.
Thanks

If you double click the hard drive icon on the top right hand corner of your desktop, you will see the System folder. Double click that, then double click the Library folder, and then double click the folder called Extensions.

You are now in the Extensions folder that contains all the drivers that make your system work. Find AppleAzalia.kext, right click it and send to the trash. You will have to enter your password.

Then navigate to AppleHDA.kext and delete that too - same process. Drag your new kexts into the Extensions folder (you will need to authenticate for each one you drag in).

Finally you will need to repair permissions. If you are happy with the terminal open that up (it's in your Applications/Utilities folder) and type in the commands from 3,4 &5 in your post above. Alternatively, download this script to do this for you automatically.
You need to leave it to run a while - it looks like it is stuck on 20% but it will get there eventually.

Reboot, you can go into system preferences/Sound and you should now see options for adjusting your sound output.
