If I understand what you're asking, you can just set the volume back to 1 when it gets to zero and you stop your interval. If this isn't what you want, then please explain what you mean by "after the event is finished".

<script>
function fadeOut() {
    var volume = 1;
    var fade = setInterval(function () {
        api_setVolume(players[0], volume);
        volume -= .1;

        if (volume <= 0) {
            clearInterval(fade);
            api_setVolume(players[0], 1);
        }
    }, 1000);
}
</script>

Also, checking a volume===0 is very dangerous with floating points values. You should check for <= 0.

Why the downvote? If this isn't what the OP wants, then please explain what they want. The question isn't very clear so I'm trying to figure it out for them.
