I added some music tracks to my game using SoundCloud. In general, it works great. The music plays perfectly for me. When my first player joined my game, the music automatically started playing for him. However, when my second player joined the game, the music did not play for them. I had to stop and restart the music in order for my second player to hear it. In order to reproduce the problem, I join my game. I had previously pressed the play button on my music track, as well as the repeat button. When I join my game, the music automatically starts playing. My second player then joins the game and does not hear the music. I press the stop button on the music track, then press the start button on that same track. My second player then hears the music. I'm using the latest version of Google Chrome on Windows 10. The player with the problem is using the latest version of Firefox on Windows 10.
