BB Tour not playing notifications

[IronFistOfDeath]

Just got my tour yesterday and it's already having problems.  I've been through the profiles, set it to normal, checked each notification's settings, and it all adds up to: they should be working.  The only thing I can think of different between yesterday and early this morning, and now is I used the Voice Dialing.  Anyone else having issues with their Tour?  Anyone know a possible fix besides restarting the BB.  Already done that.
