Say if I change from 44.1 kHz to 96 kHz then Sound and Audio CPL should
show all formats related to 96 kHz.
In Windows 8, it shows all formats (different bit depths) related to 96 kHz
as well it shows one entry for 44.1 kHz. This entry (44.1 kHz) is selected
as default entry.
Yes, driver is exposing preferred format in "PropertyHandlerProposedFormat"
GET request.
