It did not work at all 2. 

Cannot mix patched AppleHDA with the Post #1 methods. Confirm native AppleHDA.kext is installed.

With Realtek ALC AppleHDA Support kext Installation method above,

Delete config.plist/KernelAndKextPatches/KextsToPatch/ALC898 Binary and Devices/AddProperties.

Reply with new IOReg and AppleHDA898.kext and AppleHDA.kext.

Hello Toleda 
I did as you specified. But it does not work 
I was perplexed, then 

thank

https://www.dropbox.com/s/8271b9yis5loyxr/Sss.zip

As a result, it works fine. 

Now I have HDMI audio does not work.

Lucky.  Ended up with patched 898 AppleHDA.kext.  Audio will break with next update.

Start over with Realtek ALC AppleHDA Support kext Installation method above.

Yosemite/HD4600 HDMI audio does not work, note sound assertions.

AppleHDA898.kext try to load it turns out that it was not loaded, but AppleHDA.kext.

AppleHDAHardwareConfigDriver-2.6.1 is not native. Backup and remove installed AppleHDA.kext. Install native 10.10 AppleHDA.kext with AppleHDA898.kext.

AppleHDAHardwareConfigDriver-2.6.1 is not native. Backup and remove installed AppleHDA.kext. Install native 10.10 AppleHDA.kext with AppleHDA898.kext.

Hello toleda 

I try to do it several times and it did not work at all. 
I think this script does not seem to Yosemite. 
I have to say

You are patching a patched kext, will not work.  AppleHDA898 patches AppleHDA.kext; installed AppleHDA.kext must be native. The native AppleHDA.kext may be in Desktop/audio_ALC898/AppleHDA-orig.kext, unless you ran the patch script more than once.

 

Your choices:

1. Use the patched AppleHDA.kext, remove AppleHDA898.kext

2. Use AppleHDA898.kext, remove the installed AppleHDA.kext, install native 10.10 AppleHDA.kext and add AppleHDA binary patch to config.plist/KernelAndKextPatches/KextsToPatch/898 AppleHDA binary.

10.9.3 it works and why you like them in spite of it. 

I do not understand

edit..10.9.3 it works and why you like them in spite of it. 

The native AppleHDA.kext I have a question (Ie, the original) that have not been correct before. 
AppleHDA898 file to patch it up, this is not an error. As I've posted before, pictures to look at. 
And it will be a patch file. AppleHDA.kext this before the patch file to AppleHDA898. 
I do not understand

It is based on this

 

10.9.3 it works and why you like them in spite of it. 

I do not understand

10.9.3 works with 898 patched 10.9.3 AppleHDA.kext.  Use same 898 patched 10.9.3 AppleHDA.kext in 10.10.

AppleHDA898.kext only works with native AppleHDA.kext; it is not working.  AppleHDA8series.sh script failed., download updated script.

 

Native 10.10 AppleHDA.kext means original kext with no patches applied or files removed.

post-1116670-0-03630200-1403834912_thumb.png

I want to know why yosemite 10.10 not copy files to the S / L / E as version 10.9.3 ago. 

Clarified with the help

Or how to install it yourself, or use Kext Wizard.
