My audio notes from Alienware 15R3 after working with InsanelyDeepak. Hopefully it's same audio hardware as 17R4?
Audio
Download latest ALC298 package ALC298 AlienWare.zip, see below
and also codec commander
https://bitbucket.org/RehabMan/os-x-eapd-codec-commander/downloads/
and install.

- Be sure to use latest FakePCIID kexts including FakePCIID_Intel_HDMI_Audio.kext.
- download and install Codec Commander kext
- download and install ALC298 Alienware package. Install - a) AppleHDA.kext. b) run the AlcFix.
ALC298 AlienWare.zip
Everything works except external mic. (If you plug in headphones+mic, headphone mic will not detect. However, internal laptop mic works...)

Also, did you mention Nvidia is not working?
INSTALL NVIDIA DRIVERS
Download and install Nvidia Pascal Mac drivers for your version of Sierra.
https://www.tonymacx86.com/threads/...for-macos-sierra-10-12-6-378-05-05-25.227494/
Install but DO NOT reboot yet.
Find, download, and Install Lilu.kext and NvidaGraphicsFixup.kext
Also, go to Clover configurator (or use a plist editor) and set > System Parameters > NvidiaWeb. Also check Inject System ID
Check and make sure Nvidia menu bar is set to Nvidia Web Drivers
Run Kext Utility to rebuild your caches
Lilu and NvidiaGraphicsFixup are critical or you will black screen. (If this happens you need to set a fake graphics ID at clover boot to boot in VESA mode so you can install those kexts, or uninstall Nvidia and try the process again.)
As mentioned above you need to be on the latest FakePCIID kexts too.
