Same problem here, managed to make it kind of work (front plug) by:
1) i ran alsamixer and turn "Independent HP" [OFF]
and turned everything up
2) in gnome volume control, i selected "analog output"
Headphone
I installed hplip 3.9.6 and the hpcups driver gives me error with
"incorrect paper" whenever i try to print on "tear-off-tab 10x15" photo
paper or 120mm CD/DVD. In fact I can't even find tear off tab paper so I
tried 4x6 inch with same result => back to 3.9.4 with 2.8.7 hpijs bin
