This is the new Dell model of SB Live! According to the Creative Open Source page. The Dell CT0200 -- The new Live 5.1 card from Dell (CT0200) is not based on the EMU10K1 chip, so the EMU10K1 driver available at SourceForge won't work with it. The snd-((emu10k1)) ALSA module does not work either. Since ALSA 1.0.5, a new driver module snd-emu10k1x is introduced to support this different model.
