[Fix] 10.11.4 broken audio with AppleHDA injector (dummyHDA)

Autines said:
Hello, Dear RehabMan. I face the problem with AppleHDA. I patched AppleHDA as usual. It works great before upgrade to EI Capitan. But in EI Capitan, there is no sound comes out from loudspeaker. Mic and headphone is good. I tried several times but nothing changed. I get stuck for a long time. Would you please help me in your free time ? My device is Conexant CX20561. Thanks!

And here is the files you may need. https://goo.gl/JMTs0j

You have no AppleHDA injector installed. This guide does not apply to you.

Yes, I just wish you could help me to solve the issues mentioned above. I really have no idea how to deal with it.

Yes, I have read it.I patched it successful. And it works in Yosemite and before. When upgraded to EI Capitan, something wrong. Device has been recognized. But internal speaker is gone, Mic and headphone works. Is there something special in EI Capitan?

It is clear from your kextcache output that you don't have patched AppleHDA or an AppleHDA injector installed.

Please open a separate thread. Your problem is not related to this topic.

Yeah, I restored original AppleHDA. Ok, I will open a new thread and provide some files with patched. Wish you could do me a favor.

Your kextcache output shows nothing. Therefore, no patched AppleHDA installed; no AppleHDA injector either.

Since you're not using an AppleHDA injector, this guide does not apply to you.

If you're using patched AppleHDA, expect that the 10.11.4 update will overwrite your patched files. You will have to reinstall the patched AppleHDA.kext.

Thanks. Narrowed down my problem and now sound is working :lol::p:clap:

HI, I have updated my OSX to 10.11.4, and my sound got broken after. I have tried the current guide and I had no luck. I have got the ALC283.

here you will find the debug info:
