No, it is what the device driver reports. Some day I might add something
to the code to allow a single channel by skipping every second data word.
I have the same problem under Linux with my laptop but oddly enough
the laptop works with both mono and stereo input under Windows!!!

It is still a bit early, I will soon upload the next version
Linrad-02.00c which might be a little better... You tested 00a 
but 00b which I uploaded yesterday might already have solved 
some of the instability problems. 

Adding some code to pick every second data word for a stereo 
device will not be too complicated, but that will have to wait
untill Linrad-02.xx is reasonably stable.
