Sleep no longer works with Multibeast 6.3 optional HDMI HD 4000 Audio patch.

Define "Sleep no longer works".

Auto Sleep as set in System prefs/Energy Saver timer does not happen.
Manual Sleep from Apple Menu /Sleep puts display only to sleep, Cpu and psu fan continue.
At this stage it disappears from the shared network on my other machines.
Then can not wake display from keyboard or mouse, needs to reboot.
I've attached a short console log.
Without any HDMI audio patching sleep always worked as normal.
Thanks for looking at this Toleda, much appreciated.

Sleep problems are not caused by enabling HDMI audio (native on native hardware). Proven with many experiments and the majority of HDMI audio users. Your issue is specific to your system. Suggest a clean install.

That worked.
Thank you once again.

9 Series/ALC1150, see Quick Fix for Onboard Audio on 9 Series Motherboards. 1150/green motherboard port is not working; use green front, black or orange.
9 Series/HD4600 HDMI audio, not supported at this time.

Attached dsdt/HDMI audio edits are for HD4000 HDMI audio, does not support HD4600.

See Haswell HDMI Audio. Summary: no native OS X HD4600 HDMI audio support.
1. HD4600 HDMI patched AppleHDA.kext, see link above.
2. HD4600 framebuffer edits, see HD4600+/HD4000/HD3000 Framebuffer Edits
3. HD4600 dsdt edits. Attach dsdt is not native. (native with compiler errors is better than edits and no compiler errors). Try the attached 9 series/HD4600 HDMI audio edited dsdt. HDMI audio will not work with this dsdt if 1 and 2 are not installed correctly. You will not be able to recompile the attached dsdt successfully. Consider the dsdt experimental and may not boot; try at you own risk.

Reply with the native dsdt and IOReg with or without working HDMI audio.
