I'll try this as soon as I get home. I also created a DSDT with just the audio injection to see if it's an HDMI audio edit that's screwing it up.
BTW, my DSDT works perfectly in Lion but the issues I'm having are in Mountain Lion. I thought it was an HD6870 problem since AMD cards are having so many issues in Mountain Lion but once I take this DSDT out and boot without it, all sleep issues disappear. Thanks again for your help, I'll let you know later on how it works!
