Music object isn't working properly

[nshkoda]

So, i had this issue(which i've fixed, but want to post it here):
I have Music object, which volume i'm changing depend on button click. The issue is : when i'm setting volume to 0f and then try to change to 1f, it'll be muted all the time and setting volume to 1f wont help, but if i'm setting volume to 0.0f it works fine, and i can't see why
