Alsa Problem

[marimasse@hotmail.com (mamas)]

I installed Debian testing (2.4.27-1-386) with all of its Alsa packages
(apt-get install...) so, afaik, I should get full support of my audio card
(Terratec EWX24/96 i.e. ice1712).
During boot the card gets well detected (Detecting Harware) but then, when
"Starting Alsa" comes out, I can see an error message stating "no soundcard
found".
If, as root, I use alsaconf I get the message
"No supported PnP or PCI card found".
But using lspci I get (amongs the rest):

0000:02:0d.0 Multimedia audio controller: VIA Technologies Inc. ICE1712
[Envy24] PCI Multi-Channel I/O Controller (rev 02)
        Subsystem: TERRATEC Electronic GmbH: Unknown device 1130
        Flags: bus master, medium devsel, latency 32, IRQ 21
        I/O ports at df80 [size=32]
        I/O ports at dfa0 [size=16]

        I/O ports at de80 [size=64]
        Capabilities: [80] Power Management version 1


I found many posts with suggestions about OSS drivers preventing Alsa driver
to load if loaded before it, but that does not seem to be my case, as lsmod
prints out:

so I don't see any sound driver loaded but soundcore which, as stated in
Alsa's readme files, has to be there.

Any ideas?
