Does it show up as expected in the "PulseAudio Volume Control" app?
(In reply to Nate Graham from comment #2) > Does it show up as expected in the "PulseAudio Volume Control" app? I don't know how to open "PulseAudio Volume Control" app. How do I do this? Some update was downloaded and the option appeared.
It's a 3rd-party app. Can you install it and see if notification sounds are configurable there?
