Thanks, Nick. I called Tracertek - the soundcard guru was
really
helpful. He doesn't know about linux support though.
I checked ALSA Matrix and they give these instructions to
get linux to
play nice with the chipset (which may be a little beyond my
abilities):

Template start
If you are looking to specific hardware and you would like
to add an
extra information for selected module, please, do not modify
paragraphs
between Template start and Template end. Add extra
information above /
bellow for the specific Matrix:Module-* page.

Introduction for ICE1724 soundcard
There are two ways of getting Linux drivers to work, you can
either
compile them into the kernel or build them separately as
modules. Read
the Kernel-HOWTO for details of how to compile a kernel.
You must turn on the sound support soundcore module. This is
in the
kernel. Look in the sound drivers directory and it should be
the first
option. Most people enable the module setting. That way you
can load and
unload the module manually if you have multiple
soundcards/devices or if
you intend to debug or use cutting edge software which may
cause your
drivers to halt sometimes. Of course it also means you have
more control
of your system.
Most modern distros come with soundcore compiled as a
module. You can
check this in numerous ways. The easiest way is to type.
modinfo soundcore
If this command returns that you have this module, then you
don't need
to recompile your kernel.

Quick Install
NB. If you are using hg (mercurial) then you need to type
./hgcompile "or" make build
instead of
./configure
In a shell type these commands:
Make a directory to store the alsa source code in.
cd /usr/src
mkdir alsa
cd alsa
cp /downloads/alsa-* .
Now unzip and install the alsa-driver package
bunzip2 alsa-driver-xxx
tar -xf alsa-driver-xxx
cd alsa-driver-xxx
./configure --with-cards=ice1724
--with-sequencer=yes;make;make install
NB. If you are using drivers before 0.9.4 then you need to
run
./snddevices
If you use devfs then you should not run the snddevices
script
The snddevices script sets the permissions for the devices
it creates to
root. You should
chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi
Now unzip and install the alsa-lib package
cd ..
bunzip2 alsa-lib-xxx
tar -xf alsa-lib-xxx
cd alsa-lib-xxx
./configure;make;make install
Now unzip and install the alsa-utils package
cd ..
bunzip2 alsa-utils-xxx
tar -xf alsa-utils-xxx
cd alsa-utils-xxx
./configure;make;make install
Now insert the modules into the kernel.
modprobe snd-ice1724;modprobe snd-pcm-oss;modprobe
snd-mixer-oss;modprobe snd-seq-oss
NB. For drivers older than 0.9.0beta11 use:
modprobe snd-card-ice1724
Now adjust your soundcards volume levels. All mixer channels
are muted
by default. You must use a native mixer program to unmute
appropriate
channels, for example alsamixer from the alsa-utils package.
Note that
some usb-audio devices do not have internal mixer controls.
alsamixer
You can also look at the utils/alsasound file. This script
is designed
for the RedHat distribution, but it can be used with other
distributions
which use System V style rc init scripts. This will allow
you to load
your modules at boot time. If you want to do this you could
just compile
them into the kernel instead and save yourself the hassle of
coming to
terms with the rc init scripts.

Setting up modprobe and kmod support
Before you send a mail complaining that "I don't have
/etc/modules.conf,
where do I find it ....." ,The /etc/conf.modules has
been deprecated
with a few distro's so in your case, it may still be
/etc/conf.modules.
Basically they are both the same, but recent version of
modutils uses
/etc/modules.conf instead. Nothing to worry about as such,
optionally
please update to latest version of modutils. This should
solve your
problem.
Here's the example for this card. Copy and paste this to the
bottom of
your /etc/modules.conf file.
Note to debian users: You need to save this information into
a file in
the /etc/modutils/ directory (Eg. /etc/modutils/alsa) and
run
update-modules
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-ice1724
# module options should go here
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1 alias sound-service-0-0 snd-mixer-oss alias
sound-service-0-1
snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias
sound-service-0-8
snd-seq-oss alias sound-service-0-12 snd-pcm-oss
NB. For drivers older than 0.9.0beta11 use:
snd-card-ice1724
To copy and paste the above to your /etc/modules.conf file
follow these
instructions.

file

Native Devices
After the main multiplexer is loaded, its code requests top
level sound
card module. String snd-card-%i is requested for native
devices where %i
is sound card number from zero to seven. String
sound-slot-%i is
requested for native devices where %i is slot number for
ALSA owner this
means sound card number. The options line allows you to set
various
config options before the module is loaded. String snd_id
lets you set
the name of the card which is returned in the
/proc/asound/cards file.
Other options may be available which are card specific. The
options for
these are found in the INSTALL file or above.
xyz localhost#pico /etc/modules.conf
# ALSA portion
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-cmipci
options snd-cmipci id="first" mpu_port=0x330
# OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
NB. For drivers older than 0.9.0rc5 use:
options snd-cmipci snd_id="first"
snd_mpu_port=0x330
The "snd_" prefix has been removed from the
"module options" to fit with
the kernel standard.

Autoloading OSS/free emulation
We are finished at this point with the configuration for
ALSA native
devices, but you may also need autoloading for ALSA add-on
OSS/Free
emulation modules. At this time only one module does not
depend on any
others, thus must be loaded separately, snd-pcm1-oss.o.
String
sound-service-%i-%i is requested for OSS/Free service where
first %i
means slot number e.g. card number and second %i means
service number.
xyzlocalhost#pico
/etc/modules.conf
# OSS/Free portion - card #1
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
# OSS/Free portion - card #2 (cmipci)
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12
snd-pcm-oss
The alias for snd-seq-oss is not necessary on the second
device, because
there is only one /dev/sequencer, regardless how many
devices you have.
The .asoundrc file
Find out more about this file here.
This file allows the you to have more advanced control over
your
card/device. Some very useful applications will not work
without it. The
.asoundrc file consists of definitions of the various cards
available in
your system. It also gives you access to the pcm plugins in
alsa-lib.
These allow you to do tricky things like combine your cards
into one or
access multiple i/o's on your mulitchannel card.
Below is the most basic definition.
Make a file called .asoundrc in your home and/or root
directory.
vi /home/xxx/.asoundrc
copy and paste the following into the file then save it.
pcm.ice1724 {
type hw
card 0
}
ctl.ice1724 {
type hw
card 0
}
