Audio support of the CS4235 with the existing CS4232 driver will not
work because the 4235 does not support ulaw, alaw or adpcm.  sequencer
support probably doesn't work for any of the crystal chips because of a
code ordering problem in cs4232.c.   I'm attaching a patch file for
2.1.131 which fixes these problems on my CS4235.

As Tony and Keith point out, all the settings must be correct.  I use:

modprobe cs4232 io=0x530 irq=5 dma=0 dma2=1 mpuio=0x330 mpuirq=9
modprobe opl3 io=0x388

Let me know how this works.
