That's it, out simply. I can mitigate the problem by modifying the DSP
tuning to not have such a dramatic level change between DSP On/Off but
that comes at a cost of reducing the quality of the DSP process
itself. Hence the request for info on a mechanism that our GUI App
could know whether the device is in Exclusive Mode - if we knew that
we could kick in a mitigating/correcting DSP...
The whole point of "exclusive mode" is that the application wants a
direct pipeline to the hardware, without any interference from kernel
modules or filters or APOs of any kind. That is the reason it exists.
Some application writers have decided, for whatever reason, that
exclusive mode is somehow "easier" than shared mode, but that's a
misunderstanding on their part.
