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):
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=tree;f=sound/pci/ice1712

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:
http://ubuntuforums.org/showthread.php?t=843012

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.
