REALTEK ALC282 v2

Hi people,

This is a preliminary installer to activate the sound card REALTEK ALC282-v2 (10ec:0282) with LayoutID 1 or 3 in MacOS. This installer does not contain AppleHDA patched Kext. To work properly, it must be installed over vanilla AppleHDA.kext.

I want to thank the whole community for their efforts and content provided, because without these it would not be possible to create this installer.

I would appreciate comments and suggestions!!
