I'd Just like to add something about the audio here in case anyone else had the same problem.
AUDIO CLICKING AND POPPING FOR GREEN PORT IN 10.8.2, but NOT in win 7....
Black port works fine, swtiched to black port..
I looked all over the net and couldn't find another hints of this same issue.
Here is my system:
GA-Z77X-UP5 TH
i7-3770k
Tuniq Tower 120 Extreme
16Gb G.Skill Ripjaws X
XFX Radeon HD 4890
128B Samsung 840 Pro (running 10.8.2 from app store, Unibeast+Multibeast method)
60gb Crucial m300 (running Win7 64bit Ultimate, boot to this with F12, no boot loader)
2x 2TB Toshiba 7200RPM Drives
2x 1TB WD Scorpio Black drives
Antec Sonata Elite Case
Seasonic X650 PSU
At first I installed using the HD4000 internal graphics and ran on this for a while, But i was able to add the Exotic drivers batch for my Radeon HD 4890 Card... and it get full acceleration and it's stable. I have disabled the HD4000 in bios and I'm not trying to get dual graphics from this setup... (single monitor, 27" Dell U2713HM)
Now, the audio WORKS exactly how described in this guide.
I did iMac 12 system profile first, with the 898 codec for no dsdt... and i got sound.. however... I had clicking and popping sounds from my speakers, seemingly randomly, almost like there was interference from something electrically.
I tried disconnecting the front panel audio cable from the board. No change
I tried booting into windows 7 to see if I hd the same problem, however the noises are not there when booted in windows.
I turned the speakers all the way up in Win7 to hear if perhaps it is a hardware problem not OS related, but it was totally silent.
Booted back into 10.8.2... changed the system profile to Mac Pro 3.1... no change...
Reboot and tried reinstalling the 898 codec for No DSDT, no change
Reboot and tried installing 898 for WITH DSDT, just out of frustration, no change...
So... thinking out of the box here... I unplugged my audio cable to my logitech desktop speakers from the green port, and moved to the black port.
Then I went into the audio settings, and I changed to the second Line Out. I changed where the system sound effects come out of as well, to the second line out.
Success! I now have CLEAN audio, and the sound plays as needed.
In windows 7, I was also able to use the Realtec Audio Config Panel, in the Control Panel Menu, to set the Black port to be the system output.
It was a little tricky, but with the Gigabyte drivers installed from the CD, i could see that the black port was sensing a cable plugged into it... so i double clicked the black port, and it asked me "what have you got plugged in here?" with a list of boxes to check... Rear Surround had been checked, but I changed it to front speakers, and that was it! Now i am using the black port for my front speakers in win7 and the mac side...
It MAY be a hardware related issue, but I'm not going to RMA the board because of it because i found a work around. I also assume that since the green port works normally in win7, there isn't a true hardware problem, just some freak thing with my 10.8.2 install
Anyways...
I'm very happy with the setup. Thanks everyone for all your tips.
It still says "unknown AHCI controller" but i haven't bothered to fix it if it's just cosmetic.
I also would add that the Marvel Sata ports are working, Front AND rear simultaneously. I have a Sata DVD burner connected to the internal one all the time, and an Esata enclosure on he external at boot. (i don't think hot swap works on those)
I've been able to get mild overclocks and so far i haven't had a single KP or freeze.
Couldn't be happier!
