[SoulFlight]

I currently try to use Il2's EAX sound support on a Creative X-fi extreme using Alchemy on Win7 64bit. It seems to work fine but there is a strange and disturbing sound effect on under 500m altitude. All sounds are played as if hearing them very loud inside of a bathroom, even if the emitting object is around 2 km away.

So, is EAX worth the troubleshooting and have I overlooked something important here? thx
