Thank you for providing a solution, unfortunately I am not sure how to patch DSDT's at all, I tried MaciASL but it just throws up like 61 compiler errors.... I was wondering if you could patch it for me please? Thank you

not sure how to patch DSDT's
MaciASL is a text editor. Find the first 3 lines and the last line of the patch in the dsdt, add a space before the last line and paste Method (_DSM... in the dsdt. Compile, save, install and restart. The edited dsdt looks like the patch above when edited correctly. If there are compile errors, attach the disassembled (.dsl) version of the edited dsdt.

Hi. I currently have a functional hackintosh running El Captain with this small bug. After around 3 hours of use, I lose audio from my computer. I can't hear anything coming out of my monitor nor headphones if I plug them in. Video starts to get buggy too. Youtube goes apeshit; it begins to speed up and slow down. A normal restart "fixes" the problem, up until around 3 hours. I've also noticed that if my computer goes to sleep past those three hours, it doesn't wake up (no video, computer turns off after 1.5 mins).

I've been having trouble with audio since day 1. Multibeast didn't work so I used this: https://github.com/toleda/audio_CloverHDMI/blob/master/audio_cloverHDMI-110.command.zip
I used a combination of Tony's guide and the Skylake Starter Guide 10.11.0-10.11.3 (.4 didn't work for me, and I saw some guy on reddit has success with the above zip). Please help! Thank you in advance.

Hi toleda,

I have a EVGA GTX 950 graphics card and I'm trying to enable HDMI audio. The audio_cloverHDMI-110.command states that "unknown acpi PCI0/graphics name"

I'm running:
-10.11.5 (15F34)
-GA-z97MX-GAMING5
-Bios version F6
-Core i7 4790K
-EVGA GTX 950
-*My integrated graphics are disabled*

I followed this very guide and http://www.tonymacx86.com/threads/amd-nvidia-hdmi-audio-easy-guide.172023/

Every file you asked is attached!
Thanks!
