Peter, you have an option to play a sound in the Notification Action, but not in the Alert Action. It seems to me that the Alert Action begs for a sound.
Could you please add a sound option to the Alert Action.
Sounds are part of the notification API, which is why they are included.
Normally I don’t like including the functionality of an action in another application (orthogonality and all that), but you’re right that an Alert often wants a sound, so I’ll ponder it.
