Hi. Thank you for a very detailed guide. Even though my system is slightly different, I was able to install El Capitan on my computer with mostly great results.
I can however, not get the system to re-enable sound after it wakes up from sleep
My system is as follows:
Gigabyte Z97MX-Gaming 5 motherboard (F5 Bios)
Intel i5 4690K (stock speed)
16GB Crucial Ballistix RAM (2x 4GB and 1x8GB)
240GB Kingston Hyper-X Fury SSD (Sata connection)
Sound works perfectly fine when I boot my computer. But once it wakes from sleep the sound is gone, and so is the input/output choices for sound in System Preferences. I have AppleHDAReset installed and running of course, but it doesn't work for me. If I choose to reset AppleHDA when sound is working the audio also breaks :/
I'm on the latest version of El Cap. Got all the Intel 9 Chipset stuff up and running according to your guide. I didn't do the CPU DDST-part, because that resulted in an idle speed of around 2.5Ghz whereas the CPU runs at about 0.8 to 1.5Ghz without the resulting DDST.aml file. According to Cinebench there is no performance difference at all, so I guess I could just ignore this step?
I've got the F5 BIOS, and according to the Gigabyte website I can't downgrade to F4. Should I instead try to upgrade to F6?
Any help with this audio problem would be greatly appreciated. I would also love some thoughts on my CPU situation. It seems to run just fine as said, but I'd like to know if I'm missing something by not using that DDST file
Thanks
