Question Multiple animations and audio sync

I am creating an AR project in that i have a 3d object attached with an animator , this animator has multiple animations scene each being triggered by buttons, now i need to make sure that the animations has proper sounds to be attached to it and plays only when the animation plays and stops when the animation changes, can anyone suggest me a good youtube video to follow the same i mentioned above

 

I don't know if there is a video but you can do that by using timeline. First, create timeline and drag into scene, it will create an object with playable director component. Then add audio to timeline and edit as you wish. Lastly, add playable director as property in which animation you want. Every object with playable director component must be child of object you animated to add it to animation.
