Android Notification Sound Defaulting Back Instead Of Playing Custom Sound

Has anybody experienced this? I use notification.sound to set a custom sound and a phone still uses the default sound. I copied a sound from audio-resources.zip/audio/alarms/Instan

Solution 1:

Item resolved after rebooting the phone. Don't know why. It was not needed on the emulator. I guess the alarms sitting out there during the upgrade was not helpful.
