To StarXing:
      Thank you for your advise.I have tried,it make sense when I played a sine 
wave and recorded it. But when I played a mp3 or wma file (a song),it 
distortion very seriously when sample rate is 22050 or 8000,and sound good when 
sample rate is 48000 or 44100 or higher.My question is: when playing a song(mp3 
or wma),does it realy distortion when I change its sample rate?
     Actually, I wonder what does DataRangeIntersection mean, could you tell me 
  Thank you!
  Best wishes!

        Maybe you should also change DataRangeIntersection accordingly.

      Hi,I have changed them as a same value 22050,like this:


    MIN_SAMPLE_RATE 22050 // Min Sample Rate 


    MAX_SAMPLE_RATE 22050 // Max Sample Rate 


    But it doesn't work.


    When I change sample rate in the 'SetFormat', only the header changed, when 
play a wav file, it is very slow of very fast.

    Maybe you can search MIN_SAMPLE_RATE and  MAX_SAMPLE_RATE in your code and 
modify them as follows.



  MIN_SAMPLE_RATE 8000 // Min Sample Rate 

  MAX_SAMPLE_RATE 96000 // Max Sample Rate 

    Best wishes
