Step 1 :  figure out what your sound card is (I'll use an ESS1869
                                              because that's what was
                                              in my only box with
                                              sound)

Step 2 :  figure out what resources it should use (ie DMA)  This is
          one of the few areas where Windows can be helpful

Step 3 :  configure the correct modules.  Here is an example from my
          previous box.  Note that I originally had the wrong DMA
          channel, and sound was slow and horridly screwed up.  When I
          finally got around to debugging the problem it was as simple
          as using a different DMA channel.

          I have the following in /etc/modutils/my-custom (a text file
          I created).  Run update-modules as root after editing your
          config.

# sb :          uart401
# uart401 :     sound
# opl3 :        sound

alias sound sb
alias midi opl3

#
# sound card options (works!!)
# -- IO base 0x220, IRQ 5, DMA 1, MPU IO 0x330
#
options sb io=0x220  irq=5 dma=1 mpu_io=0x330

# Midi 
options opl3 io=0x388

# after loading the sound (sb) module, load the midi (opl3) module
#post-install sound /sbin/insmod opl3
