1. Install the "Maroon in Trouble" game.
2. With headphones connected, start a new game.
3. After a while, disconnect the headphones.
What happens:
2. There's a volume notification each time a sound plays.
3. There are no more volume notifications.
What should happen:
2. There are no volume notifications, because neither the sound output nor the volume is changing.
<https://wiki.ubuntu.com/Sound#notification>: "When the primary sound output changes for any reason except an app request, or when the sound volume changes for any reason, a confirmation bubble should appear ... There should be no special notification when the active output role changes."
