Alienware 15 r2 Dsdt issues

01 February 2017 - 04:09 PM



So far i was able to correct most errors in my ACPI tables and Sierra is working properly.  However i still have 2 issues:

-I already fixed immediate wake from sleep using Skylake patch for GPE = 0x6D but now i cannot get the laptop to wake from sleep using a remote usb mouse/keyboard.

-The Nvidia HDMI audio is never activated (not even listed in DPCIManager) no matter what i tried. (the intel one is activated without problems). Tried with Toleda but no joy in patching Applehda.  Now suspecting something in the ACPI tables that is preventing it from loading.


Right now i am using a USB-C to HDMI out (USB-C is controlled by the intel graphics, no probleme achieving HDMI audio from there, but still, not as good as the discrete graphics).


Any help ? I attached the original ACPI tables and the Patched ones i am using daily. Also attached IOREG with USB-C attached and HDMI audio working (iMac.ioreg.zip) and the next IOREG is with HDMI video out connected.


Thank you in advance.
