You tried installing the driver release below? Give it up.
The vendor doesn't support it, the community doesn't either and it's horribly outdated. X-Fi support on Linux is a very long and sad story. Be happy with the functionality you get from the community supported drivers or buy another card/device.
Usually there are no bass controls implemented at driver level. Use an equalizer instead. See answers to the following question: Is there any Sound enhancers/equalizer?
