Bug/Issue Music Toggle Button Not Toggling Start Screen Music Back On

Mac OS X El Capitan Version 10.11.5
Game BuildID - 1242845

When you toggle the music icon into the "off" state before the start menu scene, and don’t toggle it back on by the time it hits the white screen after the Concerned Ape logo, it keeps the music/ambience muted even if you toggle the music icon back to the "on" state. The sound effects of mousing over “new” “load” “exit” etc. still work but the music does not. The start menu ambience effects (birds chirping) start to work again if you go to “new” or “load” and then back to the start menu relaunch the game and get to the start menu without toggling the music icon to "off". Music toggles on/off fine otherwise.

A user would expect the music/ambience to start again when they toggle the music icon back to the “on” state regardless of what point in the game you are at.

I was able to reproduce this even after closing and restarting the game and it happens regardless of fullscreen or windowed mode.

I was able to reproduce this bug on Windows as well.
