I have done a lot of reading on this, and I have working sound currently, but I am not happy with my current solution. I tried to use the CloverALC audio patching script, but could never get it to work on my machine. My audio codec is ALC269. All of the scripts out there support audio layout IDs of 1 & 3 for IntelHD3000. However, the only way I have been able to get my sound working is by patching my DSDT with an audio layout ID of 5. I'm still using a patched AppleHDA.kext from Yosemite that is patched for layout ID 5 that somebody posted on this forum. However, I want to patch dynamically the native AppleHDA.kext via Clover so I can stay with the latest AppleHDA.kext for El Capitan.

1.) It is my understanding that the layout ID is specific to the system. Is this correct? If I currently have working sound with DSDT patched with layout ID of 5, then is that the only layout ID for my system?

2.) I understand it after reading that the audio patch is dependant on the DSDT first being patched with the correct audio layout ID. Is this also correct?

3.) I currently have working sound but something isn't patched correctly currently as my internal mic does not work and the input section of my sound panel shows "Internal Speakers", just like the output section.

Can somebody clarify the dependencies for patching AppleHDA.kext correctly? I have read the guides but still need some clarification in regards to the layout ID dependencies.

Thanks for any clarification. I have attached my current ioreg, clover folder, & the patch Yosemite AppleHDA.kext that I am currently using for audio layout ID 5.

Layout id is an arbitrary choice on the part of the person patching AppleHDA.

See FAQ.

I think this part finally makes sense after some additional reading. I was able to get everything working minus HDMI audio out, which I have learned, for whatever reason, REQUIRES an audio layout ID of 3. (my current is layout ID 6 using a kext Mirone made for Yosemite). I have been following the guide here (http://www.insanelymac.com/forum/topic/295001-guide-to-patch-applehda-for-your-codec/#entry1980947) to try and apply my own patch to my vanilla 10.11.5 AppleHDA.kext. However, some of the screenshots are broken in that thread, and I am stuck at applying the patching to the info.plist file within the AppleHDAHardwareConfigDriver.kext. I am using PrefSetter, and am stuck specifically on this step: "2-configdata: Here we put our configdata / Verbs codec that previously corrected." I thought I would need to put ALL of my modified codec verbs from the below codec dump, but it appears the data field only allows one line of entry. Am I trying to use the wrong information here? The CodecId was the decimal version of my audio codec below (283902569). Is the ConfigData in the info.plist not all of my "modified verbs"? Any clarification is appreciated.
Code: 
Verbs from Linux Codec Dump File: codec_dump.txt

Codec: Realtek ALC259   Address: 0   DevID: 283902569 (0x10ec0269)

Also, I think at this point I understand everywhere the layout-id is used and referenced that I could modified the existing kext I am using to change the layout ID from 6 to 3. However, I think it's best to continue and patch this latest version from 10.11.5.

Thanks! I was just reading over that guide this morning. Did you have any thoughts in regards to my ConfigData question for patching the info.plist of the AppleHDAHardwareConfigDriver.kext? I plan to finish patching my 10.11.5 AppleHDA.kext and then proceed to the your Intel HDMI guide above.

You should probably read the Intel HDA spec to understand how pinconfig data is written to the codec (there are 4 verbs involved, each one to set a different byte of the 32-bit value).
