Here is the configuration I use with a Tropez+ and my modular
driver:

  alias char-major-14 wavefront
  alias synth0 wavefront
  alias mixer0 cs4232
  alias audio0 cs4232
  pre-install wavefront modprobe "-k" "cs4232"
  post-install wavefront modprobe "-k" "opl3"
  options wavefront io=0x200 irq=9
  options cs4232 synthirq=9 synthio=0x200 io=0x530 irq=5 dma=1 dma2=0
  options opl3 io=0x388

Things to note: 

       the wavefront options "io" and "irq" ***MUST*** match the "synthio"
       and "synthirq" cs4232 options.

       you can do without the opl3 module if you don't
       want to use the OPL/[34] synth on the soundcard

       the opl3 io parameter is conventionally not adjustable.

Please see drivers/sound/README.wavefront for more details.
