Cannot play audio in Prefabs when instantiate

I created a Prefabs which has emitter and Audio, pls see below image

I use this code when hit punch button

Instantiate (particlePunch, hit.contacts[0].point, Quaternion.identity);

The emitter can show the effect. However, it did not has sound.

Do I still need to code to play the audio when instantiate the Prefabs? If so, how is it?

You need to have the Play On Awake option enabled. This will play the sound automatically when the prefab is instantiated. Alternatively, you can play the sound from a script using audio.Play.

Great! I did not notice it.

Thanks for help.
