These following defs should be moved to winquake.h somewhere.
We tell DS to use a different wave format. We do this to gain extra channels. >2
We still use the old stuff too, when we can for compatability.
EAX 2 is also supported.
This is a global state. Once applied, it's applied for other programs too.
We have to do a few special things to try to ensure support in all it's different versions.
