You seem to have an understanding of GetComponent() if you wrote the code above. Therefore the answer should be simple:

OnTriggerEnter ()
{
GetComponent(AudioSource).Play();
}

If your Audio Source is on a different object, reference it:

var aud : AudioSource;

function OnTriggerEnter()
{
aud.Play();
}

Same goes for your moving texture.
