I just installed the 18.04 daily and formatted a fresh partition (no prior home directory or any existing data used) and this is still an issue in 4.15.0-12-generic.
Can I run a command to manually turn on this jack at startup or force it to recheck that input to see if something is plugged in? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1710752 Title: Intel HDA Audio doesn't work Status in alsa-driver package in Ubuntu: New Bug description: I get no sound on most boots. In Sound settings the default Output device is HDMI / DisplayPort - Built-in Audio and there is no option to select anything else. If I unplug my line out and plug it in again it shows up in the list, automatically sets itself as default and sound works fine. In Windows 10 this unplug and replug is not required (the jack is fine).
