I've been playing explore mode a lot and I noticed this strange hissing or swishing noise while playing. This only happened once and only in explore mode. As I was dropped out of orbit this noise started. I thought it was my tv, so that's when I turned on my cable television and the sound went away. After going back to the game, there it was again. As I listen closer, I realize that its coming from the soundtrack/music in the background. It was causing the whole game to sound this way. Even shooting your gun had the same sound in the background . This sound is distracting so if anybody has heard this sound, please tell bungie!! And one more thing... jumping of your sparrow and going to aim your gun needs a lil tune up/ fix.. Thank u Bungie
