Problem with USB, HDMI audio and Shutting down on OC 0.6.8 Big Sur AMD

Hi guys it’s me again, I’ve installed Big Sur with OpenCore 0.6.8. I managed to get iServices working and booting the OS without USB. However I’m having problems with Shutting down, HDMI Audio and USB mapping.

  • As For the audio I’m using VoodooHDA.kext since I’m in AMD. On the audio info of hackintool, it shows the display, but there’s no output option. I’m using a DVI to HDMI cable that works perfectly on Windows 10

  • As for the shutting down problem, my computer doesn’t turn completely off, as my fan keep spinning and the lights are on

  • As for USB Mapping, many ports of my PC aren’t working, even if it seems to see them; also on Hackintool there isn’t any USB port, so it makes even harder mapping everything. I’m using XLNCUSBFix.kext XHCI-unsupported.kext SSDT-EC-USBX-DESKTOP.aml ; I have this kext and aml because I have followed dortania’s guide

Thanks in advance for everyone who try to help

My specs: Amd FX 6300 Asrock 970 pro3 r2.0 Radeon r9 280 16gb RAM DDR3
