hi
@RehabMan
firstly thank for your support/contribution to hackintosh community
I use this hackintosh (details in my profile & bios settings n version in zip) for music production
so here a usb audio interface is a must.
& its focusrite SCARLETT 2i4 2nd gen (firmware updated)
the problem occurs when I plug in my 2i4 in back panel USB port the audio input output works fine
but when screen graphics changes for ex. switching tabs in activity monitor / finder or webpage loading (even when cpu load only 10%) , the AUDIO BECOMES CHOPPY, same is with machines's built in sound card (through voodoo)
and whenever I plug in a usb flash drive through a external usb hub "usb drive needs power" message is displayed.
else everything works (shutdown, ethernet, twin monitor, hdmi audio, onboard audio)
previously I was in OS X 10.10.5
then same ext usb hub & focus rite 2i4 worked flawlessly (the only hardware difference was Gigabyte GT610 2gb ddr3 which I upgraded to Gigabyt gt 710 2gb ddr5 for Sierra 10.12.6 exclusively)
following this guide thoroughly
extracted acpi files but didn't had to disassemble or patch anything , just made fake ssdt-ec controller (applebuspowercontrollerusb loaded in IO) and copied USBInjectAll.kext v0.6.1 in EFI/clover/kexts
but still the problem is as it is
and if the this step in the below quotes is necessary
To specify power property overrides via USBInjectAll.kext, you must provide an "AppleBusPowerControllerUSB" in your UIAC.RMCF.
For example:
This feature is newly added in v0.6.0 of USBInjectAll.kext, so don't expect it to work in older versions.
then I got this error in Maciasl v RM-1.31. refer the image in attachments ( error for SSDT-UIAC in Maciasl.JPG )
so what am I missing , please guide me through
sorry for such a long post
thank you.
