Why is the audio muted when I stream NHL 15 Demo on my PS4?

I was streaming NHL 15 on Twitch.tv on Tuesday and my viewers were complaining that they could not hear the sound from the game. Here is a sample video: http://www.twitch.tv/thegroobster/b/562258879

Maybe because of the in game music? Honestly, I'm not a Twitch user, but do they have a problem with licensed music like YouTube does?

Recently Twitch has started muting saved broadcasts that contain copywritten music. I heard there was a similar issue at the BF4 launch. If what you are saying is true, maybe a solution can be to shut off the in game music automatically when streaming?

I have also noticed that the audio is just really quiet. It's not actually muted.
