I think that at some point in the near future volume control should be added to the options menu. Specifically volume sliders for:
-FX
-Music
-Voice
Or at the very least a Master Volume control.
This could be very helpful to members of the destiny community that wish to optimize their experience in the game, including myself as I sometimes struggle to hear my friends over a the sounds of an intense firefight.
If anyone has any extra thoughts post below.
