front headphone jack not working ubuntu 16.04, working fine in windows

i am dual-booting win 10 and ubuntu 16.04, in ubuntu itself, the back speaker jacks work fine, so does the front mic jack
the only problem lies in the front headphone jack which is perfectly functional in windows, but does not function in ubuntu,
in sound settings it shows up as plugged in but the test doesn't give any sound, neither does system sounds or anything alse

i have done lots of different things from lots of different places with no result

i did every thing posted here: https://help.ubuntu.com/community/SoundTroubleshootingProcedure

the headphone jack still doesn't work, it still comes up as pluged in

this is what it wanted me to post:
