Add a source property to skip channel virtualization for multi-channel buffers
...
With virtualization disabled, channels are mapped directly from input to output
and any input channel that is missing an output is dropped. Any virtualization
effects (such as HRTF filters) for positional cues are also skipped.
The idea is to allow applications a way to play pre-filtered audio that channel
vitualization effects could interfere with.
