Configuring Internal Rear Speakers on ASUS ROG G752VL with macOS High Sierra

Enabling sound output through the internal rear speakers on your ASUS ROG G752VL running macOS High Sierra can be a bit tricky, especially since Hackintosh setups often require specific configurations for audio to work correctly. Here's a guide to help you configure your audio output:

Guide Step by Step:

1. Identify Your Audio Codec:

   • First, you need to identify the specific audio codec used by your ASUS laptop. This information is crucial for finding the correct kexts (kernel extensions) and configurations.
   • You can use tools like DPCIManager in macOS to find out your audio codec model.

2. Install the Correct Audio Kext:

   • Once you know your audio codec, download and install the appropriate audio kext. The most commonly used kexts for audio in Hackintosh are VoodooHDA and AppleALC.
   • AppleALC is preferred for its native-like support but requires specific layout IDs to be set. VoodooHDA is more generic and easier to set up but might not provide the same level of integration.

3. Configure Layout ID:

   • For AppleALC, you need to set the correct layout ID that corresponds to your audio codec. This can be done by modifying your config.plist file in your EFI partition.
   • Research which layout ID is compatible with your specific audio codec. This information can often be found in Hackintosh forums or the AppleALC supported codecs list.

4. Test Audio Output:

   • After installing the kext and setting the layout ID, reboot your system.
   • Go to System Preferences > Sound > Output, and check if your rear speakers are listed as an output device. You might see them listed under a different name.

5. Adjust Sound Settings:

   • If your rear speakers are recognized, you can select them and adjust the balance and volume.
   • If they are not listed, you may need to try a different layout ID or switch to VoodooHDA for broader compatibility.

6. Using Audio MIDI Setup:

   • You can also use the Audio MIDI Setup utility (found in Applications > Utilities) for more advanced audio configuration. This tool allows you to configure each speaker individually.

7. Troubleshooting:

   • If you're still not getting any output from your rear speakers, revisit your kext installation and layout ID configuration.
   • Ensure that other audio enhancements or apps are not interfering with your audio output.

Important Considerations:

• Backup EFI Folder: Always backup your EFI folder before making changes, in case you need to revert to a previous configuration.

• Kernel Extension Cache: Remember that after changing kexts, you might need to rebuild your kernel extension cache using a tool like Kext Utility.

• Hardware Limitations: Be aware that not all hardware features in Windows-based laptops are fully compatible with macOS, especially in a Hackintosh setup.

• Community Support: Hackintosh communities like Tonymacx86 and Reddit’s r/Hackintosh can be invaluable resources for troubleshooting and advice.

• Future macOS Updates: Be cautious with macOS updates, as they can overwrite your custom audio settings and kexts.

Remember, audio configuration in Hackintosh systems can be quite specific to the hardware and macOS version. If you continue to face difficulties, consider reaching out to Hackintosh communities for more specific guidance based on your hardware configuration.
