I'm suprised that you havent just tried doing what TBABill said you should try when you asked the same question on the ubuntu forum-

"NOT ENABLED IN CONFIG" makes me think that you could probably even get away with just running alsa-conf.
I'm not aware of any creative/logitech speaker sets with 'built in' sound cards. If they exist, it would be via an external USB sound card, and I wouldnt trust creative to have any decent out-of-the-box support for a USB sound card. Or any linux drivers at all for that matter....
Buying an external sound card, with or without speakers, might just be buying more trouble.
