So here is my step-by-step guide for those who almost don't understand a thing. (ProBook 6570b + Clover)

1. Locate AppleHDAIDT.kext under /System/Library/Extensions
2. Copy it to Desktop
3. Right click on it -> Show package content
4. Open Info.plist in Contents folder with a text editor
5. Add
Code:
<key>com.apple.iokit.IOPCIFamily</key>
<string>1.1</string>
<key>com.apple.iokit.IOACPIFamily</key>
<string>1.2.0a1</string>
just below
Code:
<key>OSBundleLibraries</key>
<dict>
6. Save it
7. Download KextBeast (http://www.tonymacx86.com/downloads.php?do=file&id=310) to Desktop
8. Run it
9. Rebuild cache the following way:

- boot without caches (press spacebar for Clover menu, choose from resulting menu)
- rebuild cache:
Code:
[COLOR=#000000]sudo touch /System/Library/Extensions && sudo kextcache -u /[/COLOR]
- boot normally

Now You should have your sound back.

Those who are as lazy as me and have all the files needed to use mirone's AppleHDAPatcher, should use it for no brain fix.

Thank you for let me find mirone's AppleHDAPatcher because it was really easy solving the problem! :thumbup:

You really need to read post #1. It is not a matter of deleting anything. It is a matter of adding what's missing.

Thank you too RehabMan though if I didn't understand what you suggested to do, but maybe it's because I didn't understand english since that's not my mother tongue.

i was wondering if any of u guys there can patch or create an injector for my Realtek ALC3232 / ALC292 on my laptop (which i dont know why somewhere appears ALC3232,somewhere ALC292,i guess it should be same codec with 2 names or ?)

i dumped the audio codec in linux,tried to Patch many times,but never got it working,it just feels so complicated to me.

i did find out 2-3 already patched applehda/injectors on forums,but i feel all of them do really have low volume on my laptop,some of them make some cracking sounds on reboot,wake from sleep,low quality sound which hurts your ears,on headphones aswell.some are ok but have very low volume in general.

i would be really happy if someone can do this for me.

Let me know what i should attach other than the codec_dump that i made on linux.

Thank You!!

You can probably find a patched AppleHDA (or use Mirone's AppleHDAPatcher app).

See FAQ.
