kobelacious Posted April 22, 2020 Share Posted April 22, 2020 I have same specs as Usman156's laptop but audio is not working correctly, it sounds fine on internal speakers but when plugging in headphones or any other speaker through the 3.5mm jack the quality is really bad there is hissing and crackling, I have apple hda in s/l/e, apple ALC kext and CodecCommanderkext is in E/C/k/other, I set the injection value to 3 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 22, 2020 Moderators Share Posted April 22, 2020 Make sure AppleHDA.kext in /S/L/E is vanilla (untouched) and copy CodecCommander.kext to /L/E Repair permissions and rebuild cache. Link to comment Share on other sites More sharing options...
