after alsaconf no sound

[Gerard Robin <g.robin3@free.fr>]

Hello,
my sound worked fine in my box but after I ran alsaconf my system failed.

I got:
sound blaster soundcard not found or device busy
can't grab irq 65535
can't grab irq 65535
can't grab irq 65535
snd_sb8 probe of snd_sb8.0 failed with error -16
.....
.....
I booted on my second hard drive (I have two hard drives in my box)
and I commented the line snd-sb8 in /etc/module (of the first hard
drive) and after that I can boot on the first hard drive without error
but the sound doesn't work.

modprobe sb :
FATAL: Error inserting sb (/lib/modules/2.6.18-3-486/kernel/sound/oss/sb.ko): No such device

file /lib/modules/2.6.18-3-486/kernel/sound/oss/sb.ko  gives:

/lib/modules/2.6.18-3-486/kernel/sound/oss/sb.ko: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

modprobe snd-sb8 gives the same result that alsaconf now.

I am stuck with this problem. 
Can someone help me to restore the sound in my box ? 
(Please don't ask me why I ran alsaconf ..... ;-)) 
tia
