audio volume is high

[scootergrisen]

Often when i start the game the audio volume is quite high. Maby because <audio> volume is set to 1.0 as default. The higheste volume.

I think it would be better to set the initial volume to maby 0.5

Think its best to set volume after metadata has loaded.

audio.addEventListener("loadedmetadata", function(){

   audio.volume = 0.5;

}
