On Firefox, Desktop Chrome, Safari browsers, this snippet works fine:
snd1 = new Audio("sound1.mp3");
snd1.play();
snd2 = new Audio("sound2.mp3");
snd2.play();
But on the Chromecast, snd2 will not play. After some experimenting, it seemed Chromecast would not allow to load more than one audio file.
Is this behavior by design?
