You don't know that. You mean "A file with other sampling rates can be 
produced under Windows", right?

I don't know this hardware, but you could try using 48k sampling rate 
and converting to different sample rates when saving. Using sox down a 
pipe works pretty well for this (other less hacky solutions exist :). It 
seams a bit strange you can't record at least 44100 and 32000 as well, 
though. What other sampling rates did you try?
