Bibbe Posted April 21, 2015 Share Posted April 21, 2015 I've just noticed that the front audio out (Headphones) of my desktop works fine, while the rear green audio out (Line-Out) results a crappy sound quality. I tried to edit Info.plist and replace the key IOPCIClassMatch by IOPCIPrimaryMatch and put the DeviceID and VendorID of audio card in string but didn't solve the problem. Have you got an idea how to fix that problem?

Bibbe Posted April 22, 2015 Author Share Posted April 22, 2015 patch applehda . done Hey friend, my hp dv7 is working great with a patched appleHDA but I was unable to patch for my Dell Optiplex 330 with a AD1984 codec. I can't find any patched kext, I tried myself to patch many times without success, some expert appleHDA users can't patch also. So, I decided to use VoodooHDA. Thanks.
