USB sound card records only left channel and is not recognized by audacity

My Terratec usb-sound Phase 26 provides an excellent output sound
quality. However, when I record something via krecord, only the left
channel is recorded. The resultant output file is stereo, but both left
and right channel correspond to the left channel from the input of the
sound card. (Stereo recording works ok with the identical setup, when I
use the stupid other O$ on my computer).

Audacity 1.2.4b-2.1 doesn't recognize the usb sound card at all. Without
usb-sound card attached, it uses the built in sound card of my laptop
and I can record from the built in microphone. With the usb sound card
plugged in and working in as output for other applications I can record
via krecord (see above), but audacity won't show a sound card.

One minor glitch is that I have to kill artsd before k-applications will
output sound.

Any help to track these down and to get that sound card fully working
with linux are greatly appreciated.

Thanks,
Johannes
