Hi, # My question: The test case, "Wave Test", failed because my microphone driver does not support neither standard streaming not standard looped streaming. Could somebody help on it and give me suggestions how to support standard streaming? Thanks a lot in advance. #My setting: OS - Win7 x64 My driver - Microphone driver modified from MSVAD sample. # Detailed information: I checked the log of Wave Test, such Fail description,"neither standard streaming not standard looped streaming - need to support at least one" And I ran Wave Test with MSVAD sample, micarray. It failed, too, with the same reason. Many thanks, Audleyswood
