Hello, I have just installed MacOs Sierra 10.12.5 (clean distro) on my Dell m4800 (spec. in signature). Now I'm struggling with a sound problem. When i connect headphones via headphones port "white static noise"appears in headphones. This noise is independent of volume level or even of mute. Everything works fine when i listen to music via built-in internal speakers. White static noise appears only when i plug external devices like headphones into headphones port. I've tried many kexts (separetly) like:
- VoodooHDA-2.8.8.kext
- AppleHDA_ALC292.kext
- AppleHDAALC.kext
With each kext i had the same "whie noise" problem only in headphone port. Tested with many kexts and different headphones. Under Windows headphone port works fine.
For my installation i used howoarang files from this package https://osxlatitude.com/index.php?app=core&module=attach§ion=attach&attach_id=12231( DSDT.aml, SSDT.aml and config.plist).
I will be very grateful for any help. Thanks.
