hi all,
   
  I have implemented a datarangeIntersection() fonction , from the MSVAD/pcmex 
sample, in order to support the waveformatextensible format for multichannel. I 
have added other things for the channel configuration.
   
  My problem is that, in DataRangeIntersection() the clientDataRange channel 
number is always OxFFFF (65535) at the begining, when I paly a multichannel 
file with WMP. Then, my driver convert the file in  CHANNELS. 
   
  In KSSTUDIO my dataranges are good.
   
  Any solutions/suggestion for this peoblem? 
  I have seen that this problem has already appeared several times.
   
  thanks
   
  Fred
