Does not remember "Digital Output (S/PDIF)" on reboot

[Richard Larsson]

Upon reboot of Ubuntu 20.04, the selected sound device is not remembered. Instead, another device is selected as default.

Current solution: Manually open the settings and select "Digital Output (S/PDIF)", where my headphones are connected, on every reboot.

Expected behavior: Upon reboot, the last sessions selection is remembered.

It looks like you have a couple of USB audio devices so I think this might be bug 1877194... Please try commenting out:

  load-module module-switch-on-connect

from /etc/pulse/default.pa and then reboot.
