Audio clip not playing

When I hit my coin, the score works fine, the coin disappears, but the audio clip won’t play. I have an audio source on my coin, here is the code.

function OnTriggerEnter(hit: Collider){

if (hit.gameObject.name == “Character”){

audio.Play();

Destroy(gameObject);

Score.score++;

}

}

You need to assign the audio clip.
audio.clip = thisClip;
