Try first to record using arecord, instead of krecord, to see if it is a
problem with krecord or with the soundcard driver.

Not sure but I believe that audacity uses /dev/dsp, not the alsa stuff.
And if /dev/dsp is linked to your onboard soundcard, that is what will get
used. AFAIK audacity does not allow you to change this ( eg to use
/dev/dsp1 which is probably your usb card, if you enables oss emulation on
that card)
