So on Vista, you're saying that it would mix the spatialized sounds to 
stereo normally?

On XP or Linux, if the system has a 4/5.1/7.1 speaker setup, will 
OpenAL-Soft mix the spatialized sounds into the appropriate number of 
streams to send to each of the various speakers, as would be automatically 
handled in the sound card driver with a DirectSound3D or "native" setup?

Thanks,
