Audio/Sleep P55A-UD3 Rev. 1.0

[knouroozi]

So, as an early adopter, I downloaded Lion the hour it came out, then waited until the end of the day until Tony/Macman came out with a guide so I could stay on the safe side. I followed their guide, and everything works fine and dandy - except two things.

1. Restarting will cause CMOS to reset
I've tried many guides here in the forums, but nothing has helped. It really isn't convenient having to reboot the system three times just to get into OS X (First time to set optimized defaults/HPET/AHCI, Second time to fix boot order that gets scrambled, Third to actually boot).

2. Audio Hissing
Audio works, but their is a constant hissing noise in the background.


FULL SPECS/SITUATION
Core i5-750
2 x 500GB HDD (HDD 1 has OS X with 8GB Lion partition, HDD 2 has Windows 7/Ubuntu)
4GB DDR3-1333 RAM (2x2GB)
Gigabyte P55A-UD3 Rev. 1.0 F11
Audio: ALC888
Powercolour Radeon HD 5770 (1GB GDDR5) running in PCIe x8
500GB Time Machine USB Hard Drive


Any help would be appreciated, and below is my com.apple.Boot.plist as well as a screenshot of my Extra->Extensions folder. Any help would be appreciated.

OK, CMOS Reset fixed thanks to JohnnyF11: http://tonymacx86.com/viewtopic.php?f=169&t=25695&p=165317&hilit=CMOS+reset#p165317

Still working on Audio - Macman's ALC8XX w/ AppleHDA Rollback doesn't work, and neither does the ALC888 HDAEnabler.

Try the non-dsdt one for audio. Someone on this thread reported that that option solved their sound issue: viewtopic.php?f=169&t=25736&start=0

Audio hissing was not an issue with the motherboard, but with the speakers.

I have no clue how you got sound working for this Motherboard. I have had nothing but Problems with this board and sound. I've tried every one of the ALC888 Kexts in MultiBeast and not one of them works. Even had Toleda stumped as to my situation.
