I'm using it on a 770Z.  I have all the sound stuff configured as
modules.  The cs4232 module uses the ad1848, uart401, and sound modules,
and sound uses soundcore.  But running "modprobe cs4232" should take
care of loading the whole stack.

If you have built pcmcia-cs with PnP support, then you can use the
command "lspnp -v" to see what resources the sound hardware is using.
This may help you figure out what to put in /etc/modules.conf.

I think this is the key line in my modules.conf:

options cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=9

As I recall, this is typically an IRQ problem - the driver doesn't know
when the hardware is finished with a block of data.
