Thanks in advance to any and all who can offer a solution or two.
Edit: Stumbled across a post by another person with the same problem who had managed to find a solution. Big ups to Zaphod Beeblebrox who initially found the fix. The man is a god!
Use the AppleHDA.kext from the attached zip file with HDAEnabler (Not alcinject) and BINGO, pops are gone (with the exception of a single pop during boot up, and I can live with that!)
Hope it works as well for whomever needs this fix.
A couple of things, it might be a good idea to restart for the first time after installing the new kexts with -f and -x flags as my rig didn't load the drivers first time and the reboot resulted in a KP. After the -f and -x restart, the drivers loaded. The next normal restart worked without a hitch. Good luck all.
