Thanks, that helped a _bit_ .

I am wondering if loading the snd-usb-audio driver somehow sets the   
sampling rate to some default value. Well, I might move this one over
to alsa-dev for a last resort. What's also strange is that this 
happens regardless of what Sr the DM1000 is set to internally. But    
then there is no usb audio interface present within that mixer anyway.
