After laptop suspension, sound stopped working

ru flag

Sound stopped working after I came back from my lunch. I'm using a Dell XPS laptop running Ubuntu 20.04.

I ran through a few commands from help pages and my sounds in my system settings looks like this:

Sound Output settings

However there's no output device listed and the volume controls don't work. What did I install to get this new screen, because I want to remove it. I have sound but the laptop doesn't recognize when I plug a jack in, and outputs to both speakers now.

This is one of various problems I have when coming back to the laptop after suspension - sometimes the date changes to 50 years into the the future so I have to sign everything out and reboot.

Can anyone identify what it is that is showing me these new settings in Ubuntu Sound Settings window please?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
