How to make mute button?

I’m not pretty sure with the tutorial over internet. But, i’m new with unity. I have 2 button, music off and music on, so i want to combine as one button to mute all the sound in my game, how i do it? I’m not pretty sure the code. I already created 2 guitexture, and now i’m lost how to implement the code. I hope you guys can help me. Thanks!

isMute = ! isMute;

Don’t forget your semicolon!

Code to use. Simply add Mute to the OnClick listener on your button.

bool isMute;

public void Mute (){
    isMute = ! isMute
    AudioListener.volume =  isMute ? 0 : 1;
}
