I'm using Debian unstable (sid), though I haven't updated in a few weeks 
so I'm still at 0.9.4, but the alsa stuff should be the same.

OK, these are all normal settings, and where you have things enabled it 
is the same as in my 600E.

Other things to check with PS2.EXE:

check ps2 ? AUDIOCTRL
it should be enabled, and on mine the port is 538

ps2 ? PCIBUSPOWER should be set to AUTO

Here's all of the alsa-related lines from /etc/modules.conf:

alias char-major-116 snd

alias snd-card-0 snd-cs4236

alias char-major-14 soundcore

alias sound-slot-0 snd-card-0

alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

options snd major=116 cards_limit=1

options snd-cs4236 index=0 id=CARD_0 port=0x530 cport=0x538 
sb_port=0x220 fm_port=0x388 irq=5 dma1=1 dma2=0 enable=1


The last line there might be where your problem is. PS2.EXE reports the 
DMA assignment as 0,1, but alsa wants them the other way around, and if 
you have that wrong the module won't load.
