I don't know man, haven't been on .141 for a while. I can tell you it works on XperimenT 3.1.1 (.145). Have you tried clearing app cache/data for Calendar?
Yep, nothing changed.
It's not a deal breaker, since event alarms do sound when they are supposed to, albeit with the default notification sound.
It's just weird that this setting, and only this one, behaves wrong.
