Bug Description

On the vast majority of restarts of Ubuntu 16.04 I get no internal sound at all.

There are no reported issues in system settings on the only sound card I have. The volume is not muted.

On an estimated 1 in 10 restart, the sound works, and both the test sounds get played and other applications work fine.

There is no reported errors or messages on the restarts when the sound has failed.

Do you mean restart from suspend?

When answered please set status back to "confirmed".

I rarely suspended so I can't comment on that aspect. I know that sound fails often when when I restart from already logged in, or restart from windows.
Whenever I boot into Windows I always did a full Linux shutdown, so subsequent Ubuntu restart is effectively a cold start.

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
