13.6 - no hdmi & hardware acceleration & sound

Recommended Posts

* i7 2600k @ 4.7ghz

* asus sabertooth p67 (no igpu)

* 32gb (4x8gb) g.skill ripjawsx 1600mhz

* sapphire rx480 nitro+ oc 8gb

* i have fresh installed hs 10.13.6 on my system. i have tried to patch dsdt and ssdt for sabertooth p67 and 2600k. speedstep is working and my rx480 is working ok with some problems:

* i have 2 displays; 1 dp 1 hdmi. when i try to install hs, system stucked at language selection. after removing hdmi cable, installation was smooth. when booting, my system just waits at login screen, if hdmi is attached. when i remove hdmi, login input just appears. and if i attach hdmi, after login; systems sees my screen with model name, resolution, etc. but with a black video. btw, both displays were working fine on sierra.

* my second problem is hardware acceleration. when i try to export via adobe media encoder, i can switch between metal and opencl. but when i push render button, it says "software encoding". and when i try to encode an h264 video, it gives "render: failed to encode video frame". it's rendering prores files just fine. both premiere pro and davinci resolve is working fine btw; i just have problems with h264 out.

* i have tried with just radeondeinit and witouth whatevergreen; and also without radeondeinit and with whatevergreen; same result. my system is working fine; no glitches, etc. chess is working fine and macx dvd ripper also says "hardware acceleration: yes"

* ok, third. realtek alc892 is not working. i have tried to patch with multishit and also manually (applealc & luli & azal > hdef); no luck.

here is config and dsdt files. thanks!
