Hi Gale, I made such a recording and added it to the article I mentioned above (http://beis.de/Elektronik/DA2USB/AudacityMMEvsWASAPI/Audacity_MME_vs_WASAPI.html).
I describe all details there, too. The direct link is http://beis.de/Elektronik/DA2USB/AudacityMMEvsWASAPI/Audacity_MME_vs_WASAPI.html#TestSignal0to90kHz.
The recorded file can be downloaded from http://beis.de//Elektronik/DA2USB/AudacityMMEvsWASAPI/Rec_MME_192_0-90kHz.wav.
