Jukebox doesn't continue playing after turning jukebox volume off and then on.

While a jukebox is playing, if the "Jukebox/Note blocks" volume is turned past 0% all the way down to "Off", the jukebox will not resume upon turning the volume back up. The Jukebox WILL be heard the next time a player inserts a disc. This was reproducible.

What I expected to happen was...:

I was under the impression that the jukebox would continue playing where it left off after I turned the volume back up.

What actually happened was...:

The jukebox did not continue playing.

Steps to Reproduce:
1. Make sure the jukebox/note blocks volume is not set to "off"

2. Start playing a disc in the jukebox

3. Slide "Jukebox/note blocks" volume slider PAST 0% until it reads "OFF", without letting go of the slider, move it back to a valid number where it should be audible

4. you will no longer hear the jukebox until a player inserts another disk.
