Lately I noticed that there aren't any sounds (beeps, boops, plinks, swooshes, etc.) when I press buttons of any sort or if an event happens, such as opening/closing a tab in chromium, pressing a button in the system settings, the login jingle, etc.
How do I enable these sounds?
As a note: I suppose this question is a duplicate of this question, but that question is about 11.10, and the answer there did not solve my issue. I turned up the volume all the way in System Settings -> Sound -> Sound Effects
, and my master volume is also turned up all the way.
Also, my sound does work, so that's not the issue.
