Hi,
I'm using Ubuntu 10.04 Lucid Lynx (with pulseaudio pre-installed). Connect
your soundcard to USB.
For getting surround support you have to search for the line

; default-sample-channels = 2

in

/etc/pulse/daemon.conf

Remove the ";" and alter 2 to 6 for 5.1 support.

Then restart pulseaudio in terminal via "pulseaudio -k" or reboot.

Now you can control your soundcard in the systemmixer (top right corner you
see a speakersymbol). There you have to choose the creativecard. Afterwards
you can set the properties according to your needs.

Regards,
Matthias
