when i look towards a solider the voice sounds low when i look away its loud WTF?

I have the same problem, caused by bad/old/damaged sound card. Makes it kinda hard to figure out where everyone is. My solution is to get in teamspeak with [22ndSAS]Shaggy. Who can pinpoint an enemy to the exact mm within a radius of 500 miles. "Its these Medusa 5.1 surround sound headphones im tellin ya, worth every penny" (like we have heard 10000000000 times )
We know ya got hax shaggy
