I am getting similar behaviour on 17.10. If I unplug my line out and plug it in again it works fine. In Windows 10 this unplug and replug is not required (the jack is fine).

Running:
 $ amixer -c0 contents
so I can compare the non working state with the working state, the following differences exist:

Non Working:
numid=43,iface=CARD,name='Line Out Front Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
numid=35,iface=MIXER,name='IEC958 Playback Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=on

Working:
numid=43,iface=CARD,name='Line Out Front Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=on
numid=35,iface=MIXER,name='IEC958 Playback Switch'
  ; type=BOOLEAN,access=rw------,values=1
  : values=off
