README.md

Use Hackintool to determine your audio layout's pin configuration. For x1c6 owners with ALC285, it will most likely be the same and you can simply install my prebuilt files.

alc285_pin

Build

By default its code command is for Lenovo ThinkPad X1 Carbon 6th Gen with ALC285 Audio Codec with Combo Jack, you may need to change that in fixAudio function: ALCPlugFix_fixAudio

After fixAudio has been adjusted according to your pin layout, run:

xcodebuild -target ALCPlugFix

Now copy the built ALCPlugFix to alc_fix/.

Install

Running sh ./install.sh will install to /user/local/bin.

By default it search hda-verb in current work directory, if not found it will search in $PATH (May not work when it is running from LaunchDaemon because it is using as root).

  • Lenovo ThinkPad T440
  • Lenovo ThinkPad T440S
