What is your soundcard? If you have SB X-Fi the Creative drivers are
only for 64 bit Ubuntu and hardware. If you have a different card you
can probably find something on the ALSA website. Go to:

I have the X-Fi and ordered the SB Audigy 2 Value (an older less
quality card) to try and get sound on my setup.
