getting sound to stick in Etch...

[Digby Tarvin <digbyt@acm.org>]

I am having a problem getting audio functionality to stick in a 
newly installed Etch system on a Dell precision 410 MT.

There was no sound device immediately after install, so I ran
alsaconf, selected:
	legacy Probe legacy ISA (non-PnP) chips
told it to probe "cs4236   Cirrus Logic CS4235-9" then answered Y to
	Do you want to modify /etc/modprobe.d/sound
And I get
	 OK, sound driver is configured.
 	 ALSA CONFIGURATOR  will prepare the card for playing now.
	 Now I will load the ALSA sound driver and use
	 amixer to raise the default volumes.

This results in /etc/modprobe.d/sound containing:
 alias snd-card-0 snd-cs4236
 options snd-cs4236 index=0 port=0x530 cport=0x538 isapnp=0 dma1=1 dma2=0 irq=5

and /proc/asound contains:
 dr-xr-xr-x 4 root root 0 2007-10-30 15:23 card0
 -r--r--r-- 1 root root 0 2007-10-30 15:23 cards
 lrwxrwxrwx 1 root root 5 2007-10-30 15:23 CS4237B -> card0
 -r--r--r-- 1 root root 0 2007-10-30 15:23 devices
 -r--r--r-- 1 root root 0 2007-10-30 15:23 hwdep
 -r--r--r-- 1 root root 0 2007-10-30 15:23 modules
 dr-xr-xr-x 2 root root 0 2007-10-30 15:23 oss
 -r--r--r-- 1 root root 0 2007-10-30 15:23 pcm
 dr-xr-xr-x 2 root root 0 2007-10-30 15:23 seq
 -r--r--r-- 1 root root 0 2007-10-30 15:23 timers
 -r--r--r-- 1 root root 0 2007-10-30 15:23 version

Two problems...
1. after rebooting it is all gone and I have no sound again :(
   I assume the modprobe.d/sound file should be causing sound to be configured
   at boot time, but it appears not to be..
   Any ideas what is going wrong or what I still need to do?

2. No /dev/dsp, so attempting to run esd for gnome fails...
   Could it be anything to do with the /etc/modprobe.d entry:
   lrwxrwxrwx 1 root root    41 2007-10-27 21:42 linux-sound-base_noOSS -> /lib/linux-sound-base/noOSS.modprobe.conf

Thanks,
