[Help Needed] Fix Audio + Keyboard Backlight on Asus ZenBook UX333FA – macOS Tahoe Beta 3

[LUXURY W]

 

Hi everyone 👋

I’ve built my own EFI for Asus ZenBook UX333FA (i5-8265U, UHD620, NVMe, Intel AC 9560) and successfully installed macOS Tahoe Beta 3.
Almost everything works perfectly — graphics, sleep, touchpad, HDMI, USB, and webcam.
Now I only need help fixing audio (ALC294) and keyboard backlight.

💻 Specs

• Model: Asus ZenBook UX333FA

• CPU: Intel Core i5-8265U (Whiskey Lake)

• GPU: Intel UHD Graphics 620

• SSD: NVMe M.2

• Wi-Fi / BT: Intel Wireless-AC 9560 → works only with hidden SSID networks

• Audio: Realtek ALC294

• RAM: 8 GB

✅ Working

• Intel UHD 620 graphics acceleration

• Sleep / Wake

• Keyboard & Trackpad

• USB, HDMI, Webcam

• Wi-Fi (Intel AC 9560, hidden SSID ok)

❌ Not working yet

1. Realtek ALC294 Audio

2. Keyboard Backlight

EFI is attached for review.
Any help or suggestions to fix these two issues would be highly appreciated 🙏
Thanks a lot! ❤️
