Hi everybody!

I have 10.8.5 final version. Of course, I don´t have Audio. I reinstall this guide. When I reboot I listen a pop and two seconds after the black icon is grey and no sound. Any idea? Thanks!

this patch does not work anymore with 10.8.5

1. The 10.8.4 patch (-84) should not be applied to the 10.8.5 kext.  (The script does not check for this condition)

2. The 10.8.5 patch (-85) should not be applied to the 10.8.4 kext.  (The script does not check for this condition)

3. The 10.8.5 AppleHDA.kext does not work in 10.8.4.

4. The 10.8.4 AppleHDA.kext with the 10.8.4 (-84) patch works in 10.8.5.

Works Toleda!!!!!!!!!!

The secret in my case was reinstall 10.8.5 and start again.

I listen some noise in the beginning  but is not a problem for me.

 

Thanks again!

reporting problem:

 

 

1. no sound after applying combo 10.8.5. After applying your patch the AppleHDA.kext won't even get loaded. It is possible to load it afterward with kextload, but there is no difference. After reboot no AppleHDA.kext

2. 10.8.5/ga-z68x-ud5-b3/F10/i2600k/2*geforce 570

3. used the -85 patch on the AppleHDA.kext(2.4.7fc2)/your guide/2.4.7fc2

4. /Extra/DSDT.aml patched with your guide with audioID:1 as seen on the screenshot below

5. complete output of `ioreg -lx` looking for something specific, please tell me

6. I have only one line after reboot with "grep sound": kernel[0]: Sound assertion in AppleHDAController at line 504

7. Screenshot of System Information/Hardware/Audio/Intel High Definition Audio (not Devices)

8. Screenshot of System Information/Hardware/Graphics/Displays

9. Patched AppleHDA.kext

10. looking for something specific, please tell me...

toleda, your script is deleting com.apple.xpchelper.cache at S/L/Caches/. it's important for videopreview for some fileformates with space-button

here to rebuild: http://deploystudio....pic.php?id=4737

No need to double post.  Use this thread for Support with the method in Post #1.  A link for the GUI version of IOReg has been added to the first post; reply with a copy of IOReg.  A clarification, in what order did you patch AppleHDA.kext,  a. 10.8.5 Update, patch, reboot or b. Update, reboot, patch reboot or c. other?  AppleHDA binary in not loading in 10.8.5, neither 10.8.4 or 10.8.5 on 889.  I do not have a solution at this time.


toleda, your script is deleting com.apple.xpchelper.cache at S/L/Caches/. 

Thanks.  Script to be modified, will advise when implemented.

The most current patch is for 10.8.5.  The patches are specific to the released version of AppleHDA.kext.  The 10.9 patch will be available soon after the release of 10.9 and will use that AppleHDA.kext.  FYI, both 10.4 patch/10.8.4 AppleHDA.kext and 10.8.5 patch/AppleHDA.kext work in 10.9.
