How do I have the audio replay when I restart my game?

Hi all, The audio plays perfectly in my game/tutorial, but when I click on "play again" at the end and I'm redirected to the beginning layout, the music doesn't play. Can anyone tell me what I'm doing wrong?

Here is my project: https://drive.google.com/file/d/1x92KjPUmioLYL8OsaRBUcJ2zCXOSz_7H/view?usp=sharing

Thanks!

In "level 1 sheet", you set silent so you won't hear anything.

My suggestion, you should add a tag for the "1st music", example "bgm" then you can Stop the "bgm" when playing the "airwolf".

Thanks!
