Ladies and lads I would like to introduce to you functioning ALC262 drivers with headphone, internal speakers & Mic Input support. (AKA) A Realtek High Definition Audio driver.

Update: Choose the appropriate ALC262_XXX.txt file by matching it up to the last 3 digits of your Subsystem ID, Install it using Taruga's patcher by dragging & dropping the ALC262_XXX.txt file onto the patcher, rebooting and checking to see if your mic, speakers and headphones are working. If they are you can stop here but if the Mic is still not working then download the appropriate 262_XXX.zip file, extract it and perform the following steps.


1st. go to /System/Library/Extensions/
2nd . Backup then delete the file called AppleAzaliaAudio.kext (if you find it) if not its okay. now do the same to the file called AppleHDA.kext.
3rd. drag and drop the contents of my zipped file into the Extensions folder.
4th. Start up terminal & type in the following commands without the numbers or "enter"
5th. sudo -s "enter"
6th. Put your password "enter"
7th. cd /System/Library/Extensions "enter"
8th. chmod -R 755 AppleHDA.kext "enter"
9th. chown -R root:wheel AppleHDA.kext "enter"
10th. chmod -R 755 ALCinject.kext "enter"
11th. chown -R root:wheel ALCinject.kext "enter"
12th. now brows to "System/Library" and delete Extensions.kextcache & Extensions.mkext. (leopard users will only need to delete Extensions.mkext.)
13th. (for leopard users only!) open disk utility and repair permissions.
14th. close terminal, reboot & enjoy.

I hope this works for you. I offer no promises of any kind so if it blows up your computer don't try to sue me (That’s what you get for running OSX on a PC).

Ps. I realize every chip is not listed such as my chip (ALC262_600). But since all the files work just fine for me I choose to use the ALC262_F00 driver because I find it to be the best sounding driver for my system.
