I hate to be the bearer of bad news, but I was unaware with IE's incompatibility with .OGG Vorbis formats. See, Construct 2 only allowed me to convert all audio files into OGG if I were to use them in my game.
Did a Google search today, and realized that this is to be true. So unless there is a specific plug in for IE(And Safari) users, you wont hear a thing. The game IS playable by all means, but no native OGG support.
I apologize for this inconvenience. Personally I would recommend a good browser like Firefox, but many IE stalwarts may not budge.
Nothing I can do on this end I'm afraid.
