What is the best way to set up a repeating sound effect for the player's footsteps?

Browsers still suck at looping very short sound clips.

For the shooting sound in X-Type I made a few seconds long sound clip, playing it when the user starts shooting and ensure that it jumps back to the beginning when it reached the end through a callback, because some browsers don't understand the media's loop property (this may have changed in the last few months).

It's not pretty :/

var isShooting = ig.input.state('shoot');

// Did start shooting?
if( isShooting && !this.wasShooting ) {
    this.wasShooting = true;

    // Play the sound
    this.soundShoot.play();

    // Ensure that the callback is installed
    if( !this.soundShoot.currentClip.iloop ) {
        this.soundShoot.currentClip.iloop = true;
        this.soundShoot.currentClip.addEventListener( 'ended', (function(){
            this.currentTime = 0;
            this.play();
        }).bind(this.soundShoot.currentClip), false );
    }
}

// Did end shooting?
else if( this.wasShooting && !isShooting ) {
    this.soundShoot.stop();
    this.wasShooting = false;
}

ig.Sound is missing a 'loop' property that does this for you. I'll fix this in the next version!

Thanks! This does it for now. I've got it working.
Will remove this workaround come the next version.

The only issue I've been finding is this. Sometimes when I move my player to another room, if the footsteps sound was playing upon exiting the last room, it will continue looping infinitely in the new room. I thought if there was a way to 'stop all sounds' on the initialization of the level load this might help. What would be the best way to resolve this?
