Jacque,

That last suggestion about the 2nd DMA channel was
no good.  Looking at the driver, it looks like the 2nd
channel is optional and is used for recording if present.
And the driver only works with DMA channels 0,1,2,3.

You might want to try a different IRQ, sometimes the
IRQ's are shared and can be trouble(try maybe 9 or 11).

The cs4232 driver seems to be built ontop of
the ad1848.c driver, which is the audio codec
part.  It looks like this can be loaded as a
standalone driver:
ad1848=io,irq,dma,dma2,type

The last parameter is an oddball selection
for "card type", ranging from around 0-7.

You might try loading the ad1848 driver
and see if that does anything.

Karl.
