[Alsa-user] USB turntable audio through Creative EMU10K1

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I have a USB turntable and a Creative EMU10K1 sound card. I can hear 
system sounds, CDs and DVDs through the EMU10K1. I can record from the 
USB turntable with arecord (or Audacity) and I can play back the 
recording with aplay. I cannot just play a record on the turntable and 
hear it through my Creative EMU10K1. How can I get the audio from the TT 
to play through my Creative EMU10K1?

The USB TT is card 2

I can hear the speaker test audio only on the EMU10K1, not on the USB Audio.

How can I get the USB audio to play through the EMU10K1

Running Kubuntu 8.04, Alsa 1.0.16, kernel 2.6.24
