KC,
Is it just the sound, or the notification itself is not coming up? When you receive a txt msg, you should hear the sound AND see a notification on the bottom of the window, telling you that you have received a txt msg.
I had a similar issue not long ago, my phone would wake up, the txt msgs would come in, the msg count would increase, but no notification nor sound whatsoever.
I had performed the reg edit to hide the Outlook account that comes by default, because I was not using it. That broke my txt msgs notification. Put everything back and the notifications worked again.
