For a while now the chat notifications don't seem to be playing for me any more while in chat. (The Tavern on MSE, if that matters) I am on Chrome Version 36.0.1985.125 m on Windows 7.
Audio in general works just fine on my computer and in the browser. The sound notification is set to "when mentioned". (Or apparently so. I haven't changed anything there).
Playing the mp3 directly by going to http://cdn-chat.sstatic.net/chat/meta.mp3 works just fine. I get no errors in the console either upon notification.
Can anyone else reproduce this issue? Any hints as to what I could try to be annoyed again by that sound?
