Hi all after some time struggling with audio on Sierra 10.12.4 finally got patched and working AppleHDA Information: HP ProBook 4330s Sierra 10.12.4 Codec: IDT 92HD87B1/3 Address: 0 DevID: 287143633 (0x111d76d1) Hope will help someone and enjoy TODO - HDMI sound (not working now)

now use AppleHDA.kext from first post to have sound GTX760m will not work, U have in this post guide how RehabMan helped me to turn off nVidia let me know if U have solved sound

if U have ALC282 (like I have) then U should edit DSDT and put layout-id=3 not 1 and add proper kext, try to use my kext and change DSDT layout-id to 3 then U should have working sound, I have it like that and no problem at all

maybe I asked wrong did U have working sound before doing this kext replacement? or U have NO sound at all?

did U have sound before? or U didn't have sound at all?

download 10.9.2 update http://support.apple.com/kb/DL1725 use latest version of Pacifist from https://www.charlessoft.com/ extract and replace with Kext Utility or similar and enjoy :)
