Mail.app plays .caf sounds through the headphones but is there any way to make it put out the simple .aiff clicks the piezo is capable of for things like the alarm when new mail comes in or mail is sent? Does anyone know how to do this and is anyone willing? I think it'd be really helpful to get an audible alert whenever new mail arrives. I think more people would be interested in this as well and it seems simple for someone who has the knowhow. Let me know, thanks.
