Bug Description

When I start my computer I have no sound. If I unplug my line out and plug it in again sound 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

This was fixed for a while by an update that came in, but now this problem has come back.
