Getting Onboard Audio Working on an X99 System (Clover)

Here is a quick guide to enable onboard audio on your X99 system. (Confirmed working on my Asus X99-E WS motherboard running macOS 10.12.2 and Realtek ALC1150 codec)

We will be utilizing the AppleALC.kext injection method via vit9696.

1. Set up audio injection on Clover

The number in the Audio Inject menu should be the profile you want, in my case profile 1. Supported profiles are found here for your codec. Save your settings.

Clover config

2. Download compiled AppleALC.kext

3. Install AppleALC.kext

Copy the AppleALC.kext file to your /EFI/Clover/kexts/10.12 folder.

4. Reboot and test.

Use the green audio plug if available. Ensure "Internal Audio" is selected on your audio output settings.

Audio Settings Selection

Once selected, you can switch between alert sound effects to test your audio.
