Hi, @wolfman, The input doesn't switch away from the microphone on reboot. Only output changes. Here are the settings it insists on after reboot:
Only one connector selection: Microphone
Only one connection selection: Speakers
Here is what I want but it refuses to stay:
Connector has both Line Out and Headphones. I use Line Output to speakers.
On a secondary note is in 16.04 my nVidia graphics card has an HDMI output that shows up. In 18.04 it does not. I ran into lots of people having usses with this but I'm not using that HDMI at all.
EDIT: For reference, here's the output settings in 16.04 showing my graphics HDMI output I've never used.
