Public bug reported:
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
