Wasapi audio renderer and HD bistream RRS feed

  • Question

  • Hi,

    the new WAVEFORMATEXTENSIBLE_IEC61937 structure described here http://msdn.microsoft.com/en-us/library/dd316761%28VS.85%29.aspx is supposed to be used in order to have HD audio bitstream.

    Several questions :
    1/ Is it only applicable to windows 7 and new gpus as radeon 5xxx ?
    2/ Is the (microsoft) default audio renderer compatible with this structure or a custom one is necessary ?
    3/ How to fill the AMediatype structure : this is not told in the documentation (only the waveformatext is). For example, which subtype should be sent ? PCM or the IEC compressed format or another one ?

    Thank you for those precisions
