Sound doesn't work anymore

Hey Guys,

today after reboot my Sound stopped working. Sound card is detected. Even when I connect a bluetooth box there is no sound.

Do you have any idea?

A few details may assist with narrowing in on the issue. You can run these commands, then share the short-url’s in a reply.
