alsa-utils: alsa fails to recognize VIA8237 (AD1888) - no sound (ICE1712 - OK)

After upgrading to squeeze (to be honest it was clean install of 6.0) I have no
sound on AD1888 due to failure in recognition of my sound cards with "Unknown
hardware: ... Hardware is initialized using a guess method" message. I'm sure
that it is not hardware problem - I have deprecated Win XP installation so
there sound works. Moreover recently I bought ICE1712 sound card and it works
well on my Debian box. I digged into a web to find the solution but with now
success - there are bug reports with such messages ("Unknown hardware:") but no
one related exact to my problem (no sound & hardware OK). I've purged (--purge
remove) and installed alsa-utils several times - no success.

One strange thing is this message in dmesg log ("codec_read"):

[    6.018656] VIA 82xx Audio 0000:00:11.5: PCI INT C -> GSI 22 (level, low) ->
IRQ 22

Other info (Please note, that for testing purpose I take my ICE1712 out - there
are no related strings in dmesg and other log below):
