Well, I've got another update in regards to my installation. I managed to get the front sound jack on my case working by using the patch from Note 6 in this guide:
http://www.tonymacx86.com/audio/112458-mavericks-audio-realtek-alc-applehda-guide.html
I'll probably read through the guide in more detail to see if I missed something in regards to the rear ports.
Another thing I've noticed is in regards to USB3. I think something isn't working quite right with the universal USB drivers included in Multibeast 6.4. I say this because I've been experiencing some "issues" with the USB ports on my system. Sometimes when adding or removing USB devices they will fail to be recognized. I've had Flash drives blink when plugged in, but that's it. A couple of times I've had all USB ports stop working necessitating a system reset.
Hadn't really tested myself since I lack anything using the USB 3.0 technology but just to see if it the 3.0 jack works I plugged in a regular plain old 2.0 stick and had it show up with no issues. I have actually not installed a single "driver" since my system was finally up and running Mavericks.
Surprisingly everything seems to work mostly without issues, I've yet to start up a tough game due to the limitations a 60 Gb drive puts on my Mavericks "environment" but Hearthstone runs fine.
Can't really claim it's 100% stable since i've had a couple of freezes where the whole system just froze. Totally unresponsive but still showing the last images it had processed. Both times occurred about 10-15 min into a couple of ~6Gb .mkv files but I'm unsure as to why it happens since it has only happened twice.
Now that I have thought about it I wouldn't mind having the onboard audio functioning since listening to some music without my headphones could be nice sometimes. I'll attempt to get it to work and report back on how it goes.
Update:
I think it was due to my own ignorance that chimera never worked for me. Haden't realised that fakesmc was something that was required for the computer to boot and thus never installed that part. Wen't and did the ddst free install and now I can boot. Funny thing, I had to select a driver for my NIC to get it to work after this, it worked fine before but I guess something got modified and left out the NIC info.
On to the audio, I've attempted with just regular alc1150, alc1150+inte 9 support and now the link you provided without success. Neither the rear jacks or the front ones pick up that I connect something. The only output device showing up is my Vengeance 2000 headset using USB so do you have any idea?
Update2:
I've now unsuccessfully tried yet another appleHDA.kext patch found at
https://github.com/toleda/audio_ALC1150
The same link you provided pointed me to that location. You might wanna try that out and see if it enable you to use your rear jacks.
I'm giving up for the night now. 5:30 am and I'm getting tired
