[Bug 1518601] Re: [unlock install, Realtek ALC882, Green Line Out, Rear] volume slider problem



Seem BIOS disable jack detection as bit8 of the pin complex are set

Both Hp port and analog out are unknown

You have to file upstream bug report

The work around is to reenable of jack detection by hdajackretask
