The trick seems to be in getting the dma/irq settings tweaked just right.

I have a Dell Latitude CP (laptop) here with such a beast in it.  It took
me ages to get the sound going with the kernel sound driver - but I finally
did it :)

It's running RedHat 5.2 (standard kernel from the install), but I have no
idea how "generic" this solution is.

The most important thing is to get /etc/conf.modules right.  This is what I
have in it...


# turn off unwanted net stuff...
alias net-pf-3 off	# no ax25
alias net-pf-4 off	# no ipx
alias net-pf-5 off	# no appletalk
alias net-pf-6 off	# no netrom
# for the CDROM...
alias iso9660 isofs
# sound driver
alias sound cs4232
options -k cs4232 io=0x530 dma=1 dma2=0 irq=5
# no midi yet :(


This works for the audio driver, but I have yet to get the midi to work.

(Any hints on how to do this would be most appreciated - please Cc any
replies from linux-laptop as I'm not subscribed to that list, thanx).
