sound buzzing enemy dies

sound is buzzing when enemy dies but when pause is shortened sound is played too quick

var EnemyHealth : int = 10;
var soundFile : AudioClip;
function DeductPoints (DamageAmount : int) {
EnemyHealth -= DamageAmount;
}
function Update () {
if (EnemyHealth <= 0) {
GetComponent.().clip = soundFile;
GetComponent.().Play();
Destroy(gameObject, 1);
}
}

Try this code it is your code, but I did a lil modification:
`
bool once = true;
var EnemyHealth :
int = 10;
var soundFile : AudioClip;
function DeductPoints (DamageAmount : int) {
EnemyHealth -= DamageAmount;

}
function Update () {
if (EnemyHealth <= 0) {
GetComponent.().clip = soundFile;
if(once)
{
GetComponent.().Play();
once = false;
}
Destroy(gameObject, 1);
}
} `
