(Also, after step 4, when you are in the log in screen, the sound icon is in silenced state. I don't know, but if sound is silenced automatically once you enter the login screen, screen readers could be affected negatively...)
## Expected result
* The system volume is up (on the same level you left it when you logged out).
* Sound works when you play audio or video.
* When you go to "GNOME Control Center → Sound", sound controls are not disabled.
