Isoball 2: Cannot mute music, music loop is very loud and mute button works incorrectly.

[joepurin2000]

Describe the bug

It occured after opening the file and clicking "Play!" button:

1. When I clicked on speaker button to mute music, music was muted. But a while was passed, music was played very loud than normal inspite of being muted.
2. When I'd clicked it again to mute music, it worked as a volume button, that wasn't design as this.
3. Although I don't mute music, when music is played again, it's very loud than normal.

Expected behavior

1. When muting music, It must be muted forever.
2. Loudness of music must be consistent.
