Thanks for the bug report. It appears you have jackd installed, which is not a normal part of Ubuntu and might steal the sound devices before pulseaudio starts. Please uninstall jackd, restart, and tell us if the problem persists.
Also if you have 'timidity' installed please remove that too. ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878527 Title: "Dummy Output" as Audio Device in Ubuntu settings - Ubuntu 20.04.
