Downloads
The downloads are available in the Download section of this forum. Alternatively, you can download it from the link below.
Notes :
- Download the latest version for better support.
- Download only RELEASE.zip file.
- Mount your EFI partition of your system drive
- Copy AppleALC.kext and Lilu.kext from RELEASE folder downloaded above.
- Navigate to EFI/Clover/kexts/Other and place the both the kexts to this location.
- If the kext is already present in the directory, replace them with a new version
- Do not use AppleALC.kext.dSYM and Lilu.kext.dSYM
- After placing the kexts, the next step is to rename the audio device and set the device id to enable audio.
- Open your config.plist file
- Navigate to Acpi tab and add the following patch in DSDT, patches section of your config.plist.
Code:
Comment: Rename HDAS to HDEF
Find* [HEX]: 48444153
Replace [HEX]: 48444546
4. Navigate to Devices tab in the left pane, and type the layout ID under Inject.
The audio ID depends on the audio codec your motherboard uses. The common layout ID for the common audio codecs has been mentioned in this guide. The tested layout IDs are marked bold and we recommend to use them to avoid any issues.For a complete list of supported codecs and the Audio ID, see AppleALC Supported Codecs
5. Check ResetHDA checkbox under Audio section in Devices pane
6. Save your config.plist
Restart your System
After performing all the above steps, restart your system in order to enable the NVIDIA HDMI/DP Audio.
Now you should have a working HDMI Audio
Notes :
- OS X/macOS does not allow control of HDMI Audio from the system. You need to control it from the HDMI/DP Device.
- If you're having a Pascal GPU (NVIDIA 10xx), there is no HDMI Audio on connected HDMI port after boot. Try all the HDMI ports available. You can also try adapters such as DP/DVI2HDMI or DP to DP.
- For some cards, you may need to swap the port. If the active connection is a HDMI, switching to DP port will have a working HDMI/DP Audio, vice-versa.
- If you're using macOS 10.13.4 and above, and using some old cards, you'll need to use AppleHDA from macOS 10.13.3.
