Odd. I'd expect proper 3D sound if you have Generic Hardware, particularly if 
it's allowing 5.1 buffers. Can you test a 5.1 buffer? The OpenAL SDK has a 
PlayMultiChannel sample that can test it.

I don't know why it would be picking Generic Hardware over a native OpenAL 
hardware driver either, though.

AL_FORMAT_51CHN16 is only in an extension, at the moment. The 8/16/mono/stereo 
enums are standard. Plus, you need to call alGetEnumValue() with the string to 
make sure it's supported, anyway.

All you should have to do is place OpenAL Soft's DLL next to the app or in 
system32. If you leave it named soft_oal.dll, the router should pick it up and 
show it as additional enumerated devices (which an app should let you select, 
somehow). Or you can rename it to OpenAL32.dll, and it will replace all other 
implementations on the system. All OpenAL apps should work with it, unless it 
requires an extension that's not present (eg, EAX, EAX-RAM).
