I am using a Asus Xonar DX2 soundcard - and while sounds are overall excellent in the game, I always get some slight sound issues while driving. Sometimes the engine-sound disappears, I need to exit the vehicle and enter again in order to hear it again. Also sometimes the sound of explosions (especially in vehicle-battle) also gets "swallowed". Is this a game issue or might that be as well an issue of my soundcard?
Configuration of PC:
I7-2600k
Geforce 570 GTX
8 GB Ram
Asus P8P67
