Sure. Have your data range expose KSDATAFORMAT_SUBTYPE_IEEE_FLOAT instead of
KSDATAFORMAT_SUBTYPE_PCM.

Subject: [wdmaudiodev] WDM audio driver for 32 bit floating point device.
Hello everybody,
Our hardware device expects 32 bit floating point formatted samples. Is this
possible to develop WDM audio driver that can successfully advertise its pin
format as 32 bit floating point and Windows allows clients like windows media
player to feed data to the device?
Thanks
Zubin.
