Registry setting for alarm notification volume topic

I've got a dell venue 8 pro and am trying to use its alarm app.

Unfortunately, for some strange reason, when the alarm goes off, the volume of the alarm is very low. I have gone through all the sound settings and volume is maximized for them all. When i play the alarm sound separately, it is loud enough, but whenever the alarm goes off, it is very low.

Anyone have any idea on how to go about fixing it?
