Thank you for your Help Eagle, i had a couple of back to back meetings and couldn't check in.. To uninstall the Sourcery Notification just use TB. Worked great for me, the double notification sound stopped for me after uninstalling of the Gmail notifier, i think there was one time where i flashed the Rom and uninstalled the notifier without disabling the sound first and it kept going. Not sure if it will help but reinstall through settings, disable the sound, and uninstall again.
