I'm thinking that the problem might be originating with iChat. I just restarted iChat and I think that it reinstated the sound alerts. I say *think* because I hadn't asked Powermail to do anything that would generate a sound for a while, so it might have gotten its sounds back earlier.
But iChat is top candidate right now. My iChat has the Chax modifier applied to it, anyone else?
