Look, we all know how to work around it. Again with my example... what if the very first sound was blaring. On Kitkat, you could use the physical volume rocker, expand audio volume settings, and manually make adjustments from anywhere before even loading audio or video.
With Lollipop being incompatible with XPosed... you are forced to do some round about way of controlling the volume for various medias.
And no... reflashing or wiping is not going to magically install a new feature.
