IMiniport*::GetDescription() for complex audio formats

Hi,
so far my IMiniport*::GetDescription() returns a list of supported audio formats as KSDATARANGE_AUDIO.

Would it be possible to describe the supported audio formats more precisely? I.e. by returning a list of KSDATARANGE_AUDIO with WAVEFORMATEXTENSIBLE instead? I am especially interested in letting the OS know that our devices uses 24 high aligned bit in 32bit little endian audio.

Thanks,
Hagen.
