I have very similar setup. Would just add. Work checking the darkwake=8 option on the Boot menu in Clover Configurator. This seems to fix audio sleep/wake problems on this board.
Hi! I'm on day 2 of a my first ever Hackintosh build with the TH(underbolt) version of the Gigabyte UD5 mobo, and I suspect I'm having the same audio issue. It's been sporadic, and I've not been sure why. Saying it's a sleep related issue sounds like it is the cause. I've told my OSX to not put the machine to sleep. It still sleeps the monitor, and it generally requires a power cycle to get my display back, but the machine still responds, so that's not too bad, if not perfect. Also, the line out sound that I've connected to my amp is listed as Internal Speaker. Is that common?
Actually, while I'm here, I'll list my other issues (though I should probably make a new post - I dunno, I'm new here!)
1. I've also got the memory issue, with it reporting my 4x8GB sticks as 4x4GB
2. I've installed the Nvidia drivers correctly (and I am getting the native UHD res out of my Samsung monitor (via DisplayPort) but, in the Nvidia Driver Manager sysprefs pane, it still says it's using the OS X Default Graphics Driver. I've got nvda_drv=1 in my boot args, so I don't know which driver it's actually using. I ran the Heaven GPU benchmark and it did terribly.
3. No Thunderbolt. Either before or after running the Gigabyte TB firmware updater in Windows.
and the most annoying:
4. I have to reboot twice to get to the AMI bios. The first time, I ALWAYS get the led error message 62 on the mobo, which the manual reports as "Installation of PCH Runtime Services". Google-fu suggests an issue with my GTX970 GPU. Not sure what, if anything, is to be done about that.
OK, apologies for vomiting this enormous reply to your comment, which I originally intended to be a "yeah, me too!" message!
Any help you can offer, I'd greatly appreciate!
