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 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1628153 Title: [W65_67SF, VIA VT1802, Speaker, Internal] No sound at all on most restarts Status in alsa-driver package in Ubuntu: Confirmed 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.
