Fix Audio Distortion when using Headphones on Laptops [Clover/OpenCore]

An EliteMacx86 Exclusive Guide - This guide covers fixing of Audio Distortion when using Headphones on Laptops using Clover and OpenCore.

Overview

---

After enabling the Audio, you might encounter audio distortion/crackling sound when using headphones on laptops. To fix this issue, follow the steps below.

Some Audio Codecs which requires this fix

• Realtek ALC233/ALC3236
• Realtek ALC236
• Realtek ALC255
• Realtek ALC256/ALC3246
• Realtek ALC292
• Realtek ALC294
• Realtek ALC298
• Realtek ALC299

Using VoodooHDA, this can be fixed for most of the times. But as per the laptop FAQ, VoodooHDA is not recommended.

STEP 1: Add Required Kext​

The very first step is to install the required kext in order to fix the distortion.

1. Download CodecCommander.kext.
2. Extract the kext from the Release folder.
3. Mount your ESP.

For Clover:​

If you're using Clover, copy the kext to EFI/Clover/Kext/Others directory.

For OpenCore:​

1. If you're using OpenCore, copy the kext to the EFI/OC/Kexts directory.
2. Open your config.plist and add CodecCommander.kext entry in the Kernel>Add section of your config.plist.

STEP 2: Install HDAVerb​

The next step is to install the HDAVerb which will update the pin widget control when using Headphones.

1. From the Release folder of CodecCommander you extracted in STEP#1, copy hda-verb to the /Users/YourUserName/ directory.

STEP 3: Installing Jack Fix​

The next step is to install the Jack Fix script which will execute the command silently in the background.

1. Download the Jack Fix script attached below.
2. Open the Jack Fix script using any text editor.
3. Replace YourUserName with your actual username in line 2 and line 3.
4. Save changes to the script.
5. Copy the Jack Fix script to the/Users/YourUserName/ directory.

STEP 4: Execute Jack Fix​

Now the next step is to execute the Jack Fix script.

1. Double-click on the Jack Fix to execute the script.
2. Monitor the Audio, and execute the script. The distortion should be fixed now.


Note:
This will also fix switching issues for Headphones and Microphone Outputs. The script works for AppleHDA, AppleALC, CloverHDA, ADummyHDA and VoodooHDA.

Q. Is there any way to execute/run this script automatically?
A. Yes. In System Preferences, go to Users & Groups, select Login items, add Jack Fix to Login Items.

It works like a charm. Just what I needed. Today I got audio in Mojave Thanks to this wonderful site, Mirone's AppleHDA patcher, and Rehadman CodeC Comander, and credits to the Jack fix developer, I don't know who is.

Thanks for the appreciation. A long time ago, i had this issue so began to test with friend's laptops which had same issue. I tried to search and when debugging, i found the what was causing it and finally got the idea from the CodecCommander. Wrote a script and it works like a charm. EliteMacx86, Admin of EliteMacx86 forums is the developer of this fix. As it was a Jack related issue so i choose the name as "Jack Fix" and yes, it does the job. Happy to share.

Hey just wanted to say, this guide worked for me on my Alienware R5 17 - after a day of messing around with AppleALC and what not, I tried VoodooHDA + your guide and it works 100%!!

Thank you!
