Yosemite 10.10.1 Audio Issue

Hi all.

   I have recently managed, for the very first time, to get my Yosemite 10.10.1 Hackintosh working a couple days ago, ever since, however, I seem quite unable to sort out all of the audio problems that comes with it. The first time I noticed the issue I was trying to use Garageband 10.1.2, whenever I played a key, it would work but sound like it was skipping/stuttering (the same used to happen on iTunes and any other sounds only when something graphical like dragging a window or moving the volume bar was going on) I thought it was a Kext related problem; my audio codec is Realtek ® ALC887, so off I went, testing every single corresponding piece of kernel extension to this codec, but the problem, of course, persisted.

    Later on I was tweaking my Bios and found out that my Mobo had some "Auto Turbo" mode enabled, slightly overlocking my CPU, I have disabled it (never been an overclock kind of guy) and then I realised that the audio problem got even worse; Which lead me to a deeper research: BUS Speed and Busratio. I have seen some threads where people successfully got rid of this same problem by adjusting Busratio and stuff, I use Chameleon Bootloader, so try setting it through Chameleon Wizard would be ok, but as frustrated as almost every AMD user might be, I'm helplessly asking myself now: "Where the heck can I get some info on my CPU`s BUS frequency/External Clock?" all the information out there is for Intel.

Anyway, I have come to a point where my research is stirring me nowhere, so I came to ask for some help, any attempt would be dearly appreciated.

 

My Specs are:

 

AMD A8 6600k 3.9GHZ

Gigabyte GA-F2A55M-S1 with Realtek ® ALC887

8GB G.Skill Sniper 

Zotac Nvidia Geforce GTX 650 DDR5 1GB 

Corsair CX750 Power Supply

160GB SATA HDD running Niresh's Yosemite 10.10.1 with Chameleon Bootloader

 

Notes: I'm trying to get this sound fixed with onboard audio, HDMI is no solution for me, since I have no HDMI monitor available for use right now; also, I have just realised that when trying to watch Youtube videos, the audio problem is much less frequent, however, video and audio are not synchronised.

 

Thanks in advance.
