What is the best audio file format to play audio from javascript in custom chromecast receiver

I have developed a simple custom chromecast receiver for a game.

In it I play short sounds from the receiver javascript using:

 this.bounceSound = new Audio("paddle.ogg");

to create the audio object when the game is loaded, and then using:

 this.bounceSound.play();

to play the sound when needed in the game.

This works fine in chrome on my laptop, but when running the receiver in my chromecast some sounds don't play, others are delayed.

Could this be a problem with my choice of sound format (.ogg) for the audio files?

If not, what else could be the problem.

Are their any best practices on the details of the sounds files (frequency, bit depth, etc?).

Thanks
