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.

Installing the required Kext

---

Download CodecOmmander from the downloads section of this forum.
Extract the kext from the Release folder.
Mount your ESP.

For Clover:
If you're using Clover, copy the kext to EFI/Clover/Kext/Others

For OpenCore:
If you're using OpenCore, copy the kext to EFI/OC/Kexts. You'll also need to add the kext entry in Kernel section of your config.plist.

Installing HDA Verb

---

Copy hda-verb to bin
Open Terminal
Type:

sudo cp -R /Users/yourusername/Desktop/hda-verb /usr/bin

When promoted, enter your password

Download the Jack fix attached below. This is a script which updates the pin widget control when using Headphones

hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x25
hda-verb 0x21 SET_UNSOLICITED_ENABLE 0x83

Installing Jack Fix

---

Copy Jack fix to bin
Open Terminal
Type:

sudo cp -R /Users/yourusername/Desktop/Jack fix /usr/bin

When promoted, enter your password

Monitor the Audio, and execute the script. The distortion should be fixed

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!
