So after running mavericks with chameleon boot loader for a long time, I decided to try clover efi (uefi) out. My old install thread and a lot of info from what I am running is all here

http://www.tonymacx86.com/laptop-co...7520-advice-would-appreciated.html#post877159

After many hours/days I finally got clover configured for uefi boot properly. I did this all in mavericks as I knew I had a solid base in mavericks to test everything with. After I knew everything was good to go I decided to try el Capitan. Clover is awesome I must say, as it made upgrading to el Capitan very easy. I upgraded via app store. With all the kexts and edited dsdt and ssdt's in clover upgrade was a breeze.. .besides one issue

I'm running into the same issue with el Capitan as I did Yosemite, which prevented me from using Yosemite. I simply can not get sound to work. My patched applehda.next that worked great in mavericks no longer does. I have tried various applehda's and have yet to find one that enables sound. I even tried vodoohda 2.8.8 but installation fails, then tried vodoohda 2.8.8 in multibeast el Capitan, still.no sound.

If anyone knows of where a applehda.next that will work that would be awesome. It's the only thing that does not work :).

My sound card is as follows
Conexant CX20590.
hex: 0x14f1506e
decimal: 351359086

Googling Conexant CX20590 applehda.kext hasn't had good results for me.

Ease advise. Thank you

Make sure you read the FAQ regarding patches required, etc.

Hello rehabman. You originally helped me get mavericks all set up. In mavericks I had sound working by use of a patched applehda and patches to the dsdt/ssdt (I can't remember which right now) and am still using them. I do recall the patches where audio layout (mine was 12). And IRQ?

If I recall I have tried the applehda from insanelymac and it didn't work. I just noticed at the bottom of that thread there are hdaenabler.kext. I am unsure of what those do, maybe that's what I need? Any suggestions on which one if so.

My sound was working in mavericks perfectly, so I will assume all my patches are correct.
 
Well I just tried the AppleHDA for CX20590 posted on insanelymac and installed with the EasyKext Utility for El Capitan, and still no sound :(

I'm pretty stumped. Would love to get sound working as it is the only thing not working. I have attached my DDST/SSDT's for review if someone has the time to confirm my patches are correct.

Thanks

Still so stumped I have tried various patched appleHDA's and other methods, still having no luck.
 
Yes I'm pretty sure I followed those steps. I used linux to extract. And did all the patches. Brightness fix works, my amd vid card is disabled. Only thing that doesn't work is sound :( it worked fine in mavericks with a patched applehda and layout and IRQ fix patches.

The link in my op has everything I did.
 
So I was reading over the guide you posted and may have found something i missed before.

"Finally, keep in mind you cannot provide patched SSDTs without dropping the OEM SSDTs that they replace. The easiest way is to use DropSSDT=Yes (Chameleon) or ACPI/SSDT/DropOem=true (Clover) to drop all the SSDTs, then provide the patched (and unpatched) files for loading by the boot loader."

So I looked through my config.plist and think i need to make a change.

In this section of my config.plist<key>ACPI</key>
<dict>
<key>DSDT</key>
<dict>
<key>Debug</key>
<false/>
<key>DropOEM_DSM</key>
<false/>
<key>Name</key>
<string>DSDT.aml</string>
<key>ReuseFFFF</key>
<false/>
</dict>
<key>SSDT</key>
<dict>
<key>DropOem</key>
<false/>
<key>Generate</key>
<false/>
</dict>
</dict>


I think it should be changed to
<key>ACPI</key>
<dict>
<key>DSDT</key>
<dict>
<key>Debug</key>
<false/>
<key>DropOEM_DSM</key>
<false/>
<key>Name</key>
<string>DSDT.aml</string>
<key>ReuseFFFF</key>
<false/>
</dict>
<key>SSDT</key>
<dict>
<key>DropOem</key>
<true/>
<key>Generate</key>
<false/>
</dict>
</dict>


Am I correct on that assumption?

Thanks

If you have patched SSDTs in ACPI/patched, you should read about DropOem and SortedOrder as detailed in the guide very carefully.

Note: Best to use ACPI extracted via Clover, and keep the same names. It makes comparison against native easier.

Yes, I have my ssdt's in correct order.

The audio patch is applied to the dsdt if i remember correctly.

At the time i made my dsdt and ssts linux was the best way to get the acpi, I'll go ahead and redo via clover and re patch them.
