For those who want to test AppleHDA of El capitan: https://github.com/Mirone/AppleHDA_10.11_DP3

Hi Mirone,

 

I've tried your kext on DP Beta 7 but have no sound. My sound device is ALC892. Steps I used to install:

1. Install patched AppleHDA.kext via Kext Utility

2. Add Audio ID 7 into DSDT by following your txt guide.

 

Did I do anything wrong?

 

Thanks

on El Capitan I got HDMI audio working by using the same Clover configuration that I do for Mavericks.

I've managed to activate the volume controls after creating a new dummy AppleHDA269.kext based on the one I use with Mavericks and updating some sections to make more sense with El Capitan's AppleHDA.

The new kext loaded fine, the volume menu bar icon is enabled and I can even change the volume level. In System Preferences > Sound > Input I can see the Input Level changing if I make some noise next to my Internal Mic. However no sound at all is coming from the internal speakers. How's that possible if I'm using exactly the same nodes as I do on Mavericks?

It sounds like something is just temporarily disabled, just like it happens sometimes on Mavericks when I need to reload EAPDFix.kext

For now I'm not using any other audio kext... What do you suggest me, Codec Commander?

I can't remove the orignal one from S/L/E :/ 

Which version of Closer do you use ?

 

Update to v3259 at least and disable SIP to get root access.

CodecCommander works almost all the time for me, when I have issues I just Sleep/Wake to get normal sound ... I still have to figure out what kills my EAPD randomly and not so often.

I've just patched AppleHDA for ALC233 successfully. And i'd like to share some expriences about patching AppleHDA on El Capitan (GM). I hope it'll be useful :)

 

1. Binary patching

We have 5 chain hexs that have to be modified.

8419d411 --> 3302ec10
8319d411 --> 00000000
6102ec10 --> 00000000
6202ec10 --> 00000000
8508ec10 --> 00000000

2. Tools

I recommend Hex Fiend. You shouldn't use Hex Edit, because I tried to modify hex by Hex Edit but not success. That's basic way. And the way that i truly love is Clover. See more at attached files. I attached my Config.plist and AppleHDA for ALC233 only.

 

Goodluck :)
