You are correct, the driver does not know (or care) whether the thing talking 
to it is a WASAPI client in exclusive mode, or is the WASAPI shared-mode audio 
engine (which is itself just a WASAPI client in exclusive mode.)

When you say your driver supports 24-bit, do you mean 24-bit in 24-bit 
containers, or 24-bit in 32-bit containers? What values are you passing for 
WAVEFORMATEX.wBitsPerSample and 
WAVEFORMATEXTENSIBLE.Samples.wValidBitsPerSample?
