To clarify, I meant to ask if chips, other than ice1712 are affected.
From my recent research getting an ice1724 card working (Dynex dx-sc51 a cheap 5.1 channel 1723 "Via Tremor" available in a zillion configurations and boards -- the only reason I bother with this P.O.S. is that it has a waveterminal header for my Yamaha DB60XG), I've learned this is an issue that affects a lot of people and not only prosumer cards like the M-audio Delta (ice1712) but also low-end and including built-in to motherboards and media stations:
This particular card for example is documented as working with the following ( http://www.kernel.org/doc/Documentation/sound/alsa/ALSA-Configuration.txt ):

Unfortunately my $5.00 card http://alsa.opensrc.org/index.php/Ice1724#Dynex_DX-SC51, though claimed to be supported in ALSA isn't supported very well because there's no special-case code telling how many DACs, how many MPU401 ports, etc:
> ICE1724 0000:01:07.0: PCI INT A -> Link[LNKB] -> GSI 19 (level, low) -> IRQ 19
> ice1724: No matching model found for ID 0xc3140517
> ice1724: Invalid EEPROM version 1
Fortunately, when I play one of the Yamaha XG wunder-midi ( http://www.blueman.name/Creations_XG.php ) through this $5 Dynex -- really just a glorified holder for my Yamaha db60xg --I hear shredding on my headphones and I know all is well: "aplaymidi -p 40:0 vchile.mid" :-). Or as I told my sister, "best damn $20.00 synthesizer I ever bought"... reply: "twenty dollar synthesizer" that sounds like a good band-name!
With the above error message the Dynex comes up in a minimal 2-channel mode... trying different similar model= configurations, jackd pukes all over the place (sometimes locking up the machine trying to open 8 dacs when only 6 available etc)... I finally got SPDIF working, using 'plug' to keep it from balking at source-material that isn't in the exact same S32_LE bitformat needed by the card.
Checking the sourcecode to see what was up w/ it's total lack of 5.1-ness, and also to decide which model= variants to try, I noted a giant unworkable pain in the butt (this "1712" code also includes the 1724):
This results in all manner of problems and workaraounds for very minor variants of essentially the same chip: http://envy24.svobodno.com/ (mine's not on there boohoo).
Multichannel sound is a big problem, with the following as good proof:
Also a problem -- digital outs, both under ALSA and pulseaudio: http://alsa.opensrc.org/index.php/DigitalOut
I think it all needs to be solved, once and for all, across-the-board without dividing into camps and pointing fingers.
