IN-GAME AUDIO IS BROKEN

Sound is really bad in this game. I am a long time Battlefield lover since BC2 and this is just so disappointing. This is my first post whinging about a game but I had to log in and say something as this is terrible. I have a Razer Megalodon 7.1 Headset which is awesome in every other BF game so it's not my PC or Headset. The mixing is bad in this game, muffled and low flat volume. I have my headset up full noise and normally it would be too loud in a BF game but not this one. I can hear footsteps and have a general idea of where they are but I am more concerned about the lack of atmosphere and noise from everything. I hope DICE will sort this out soon. I had so much hype and hope for this game but having sound this bad goes against everything I loved about DICE in the past. It's a sad day when I have pre ordered Ultimate to play early and have only put 5 hours in since launch...
