Do not hijack another user's thread. Post to No Audio Devices - Realtek ALC AppleHDA
Do you mind giving me step-by-step instructions for this, and posting the files, like your DSDT? I'm totally new to Clover and I'm used to just ticking a box in Multibeast. It's a bit over my head. I tried the dsdt/clover folder you posted on the first page and it's not letting my computer wake from sleep...if I use my old dsdt sleep works fine.

In the evening I'll write for you a summary of what I did. Basically I cloned Yosemite in a second HDD and on it I made direct upgrade to El Capitan GM Candidate. In clover configurator I patched the DSDT and also created a SSDT which was referenced in the config.plist file that boots both Yosemite and the Capitan partition to rename the USB ports to overcome the port count issues (see the thread that I created for that which was supported by Rehabman) and deleted the genericusbxhci kext that causes kp. Once I booted with mouse and kb working I installed the Nvidia web drivers (my gpu don't like the native drivers) and finally fixed the built-in sound card issue. Make sure that you pick the iMac 11,3 in the SMBIOS in clover configurator and tick the generate c-state and p-state options if you have the i5-750 cpu. I did the clover edits in the Yosemite partition and also used the screen sharing option from a real mac to overcome the lack of mouse and kb. The working clover bootloader is still in the Yosemite HDD.@jzrodriguez98 Bit of a sidetrack here but how did you get El Captain to install in the first place?. I have the same board and firstly I was able to boot into the os x install screen but no usb mouse or keyboard. Added MacPro3,1 smbios in clover configuration but now I get a kernel panic on boot which involves (I think) the usb kext. Any pointers would be appreciated.

Regarding the sound, check the audio layout id in About This Mac, System Report, Audio. Make sure that the audio Id you select when running the command is the same that you see in the system report (I had a mismatch that I fixed by editing the id directly in the DSDT as instructed by Toleda in the thread). Check that the command patched your config.plist file as well. You may export the terminal verbose after running the command and attach it to a post here to see what's happening.
