Configure system beep

I am trying to figure out why my system sounds aren’t playing. I am using the latest RISC img.. I hear the boot beep, MP3s play fine. When I open Messenger, I don’t get the beep when new mail arrives. Nor do I get a beep when an error dialog is displayed. Any ideas? I thought there was a module in !Configure but I do not see it.

Update I am getting the system beeps now. I looked inside !messenger and clicked on the soundfile, and it said that “An application that loads a file of this type has not been found by the filer…”

I copied the relevant bits across from an earlier version of RO (I think it was from a rev 2 B install to the B+ version). Sound all fully configurable afterwards.
I posted the lack of B+ sound config in the Bug forum a while back.
