Contribution for Z170X gaming 3 tips on dealing with sleep issues with audio.
I found that a particular setting in codeccommander was causing issues when awaking from sleep (causing noise) and not properly waking. So use these two settings only in Info.plist in
/System/Library/Extensions/CodecCommander.kext/Contents
<dict>
<key>Command</key>
<data>AgR8sA==</data>
<key>Comment</key>
<string>0x20 SET_PROC_COEF 0x7CB0</string>
<key>On Init</key>
<true/>
<key>On Sleep</key>
<false/>
<key>On Wake</key>
<true/>
</dict>
<dict>
<key>Command</key>
<data>AbcIgw==</data>
<key>Comment</key>
<string>0x1b SET_UNSOLICITED_ENABLE 0x83</string>
<key>On Init</key>
<false/>
<key>On Sleep</key>
<false/>
<key>On Wake</key>
<true/>
</dict>
(Just edit the entry using VI in that file and use these dict settings only. Delete the others. Be sure to make a backup copy of Info.plist!!!)
I didn't get sleep working with Intel graphics but used NVIDIA instead. Used tonymac86 advice to get around it:
https://www.tonymacx86.com/threads/solving-nvidia-driver-install-loading-problems.161256/
Final observations for stuff I got stuck on:
1) UPDATE GIGABYTE BIOS!!!! All kinds of evil happened because I used an old bios. I'm kicking myself at the hours I spent chasing bugs in my build that turned out to be corrected b y just going to F21 (in my case).
2) POWER SUPPLY!!! I was using RaidMax Vampire which was great, and I liked it, but strange things happened. I RMAd it and they issued me a new power supply which I'm sure is find but by that time, I had upgraded to EVGA power supply that is ROCK SOLID.
3) NO MORE THAN ONE EFI boot disk ON YOUR SYSTEM. I had backup EFI's on other drives that were causing havoc with Clover and gigabyte. So now, I have backup USB sticks (4 to be paranoid) and a backup of my whole boot drive on another drive. Now I sleep well at night. I boot from the USB stick (one at a time). If I need a different bootloader (more on this in a bit), I can just switch USB sticks.
4) Needed different EFI/Clover bootloader for El Capitan and Sierra (and probably for Windows 7 too! Getting around to that later). El Capitan doesn't wake from sleep well with a bootloader that works on Sierra (with the kernel mods in Clover) and vice versa: Sierra won't boot from my El Capitan EFI bootloader. So it's best to just keep them separate on different sticks.
5) Clover bootloader install on my USB stick didn't work right for lower than 16GB stick. I had an 8GB stick and it didn't load correctly so I'm wondering about my unibeast run. Found a workaround: just format two partitions on the USB stick with GUID with the first being FAT32 (for clover boot) or just use a 16GB stick or larger for UNIBEAST!!! This confused the heck out of me for a month!!!
6) Needed to generate an SSDT to get full performance. See details at:
https://www.tonymacx86.com/threads/quick-guide-to-generate-a-ssdt-for-cpu-power-management.177456/
Loaded into ACPI/patches on EFI clover partition. Huge difference.
7) Set trim manually via
http://osxdaily.com/2015/10/29/use-trimforce-trim-ssd-mac-os-x/ and also hibernate off (for my desktop, why burn out the SSD drive?) at
https://www.cultofmac.com/227679/sa...disable-safesleep-mode-on-your-mac-os-x-tips/
Also, I left darkwake unset and am fine with normal sleep (ahhhh, sleep!) with codeccommander waking properly from sleep including audio.
8) I had SEVERE problems getting Intel 530 Graphics to run dual monitor (with the VGA port) even though this works fine in windows 7 BUT I could boot the VGA monitor fine in El Capitan. Went away when I used an NVIDIA card (NVIDIA GeForce GTX 750) I got for 50 bucks from a friend.
