I'm assuming you are also using a 600E.

1. disable 'fast boot' in bios - otherwise the machine locks up on loading the sound module.
2. I have the following in /etc/modprobe.conf. (this is something i picked up from a google search)
[root localhost root]# cat /etc/modprobe.conf
alias usb-controller uhci-hcd

# ALSA portion
alias char-major-116 snd

alias snd-card-0 snd-cs4236 
# You have to specify every damm paramter to get it working:
options snd-cs4236 isapnp=0 cport=0x538 port=0x530 sb_port=0x220 fm_port=0x388 irq=5 dma1=1 dma2=0

#alias /dev/mixer snd-mixer-oss
#alias /dev/dsp snd-pcm-oss
#alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
#options snd cards_limit=1

[root localhost root]#

3. I guess on reboot - use alsamixer to unmute (M)
4. use gnome-volume-control to crank up 'Volume, PCM, Out-gain" (perhaps others as well)
5. Test if I can play a .rm file with relaplayer
