When calendar reminders pop up on my Smartphone, the volume of my music goes
down. How do I get the volume back up? Volume level on the phone displays
100%, and volume within WM displays 100%, but the actual volume is about half
of what it was before the calendar reminder interrupted things. Restartint
the phone solves the problem, but can anyone tell me how to get the volume
back more easily?

The phone is an Audiovox SMT5600 with WM10.

thanks.
