Im a multi boot user (Win7 / Yosemite) and i have a really weird problem with the rear green jack of my board.
When i boot directly into yosemite my sound works perfect but when i reboot from win7 to yosemite i lose sound from rear green which has EAPD.
This great kext works perfect for sleep, i do get sound after sleep but i still lose sound if i reboot from windows to mac
I have to shut down my pc and boot into mac in order to get proper sound.
And another thing is that i get some errors like:
