The CMI8330 can be made to work with Alsa, but it is not at all simple. I
was only able to succeed in making playback work - not capture, which I
think is impossible. Therefore, of course, full-duplex is out of the
question. The midi synth in that chip is so pathetic I would forget about
it and use Timidity instead.
You will need to compile and install the Alsa modules, and create by hand
a suitable /etc/modules.conf. I have appended the relevant part of the
one I used to use at the end of this message....of course you will
probably have to change the IRQ's, DMA and IOPORTs to suit your system.
I got rid of my CMI8330 (it's really bad) and for only $10 bought an
Ensoniq Audio PCI with ens1370 chipset on ebay - which sounds great and
works 100% with Alsa.
But if you really want to struggle, the following quote from an old email
of mine may help you. The person I sent it to was able to get his CMI8330
working to the same extent as mine - i.e. playback only.

That's because device #0 (the default) is not enabled for playback by
Alsa. You have to use device #1, by specifying it on the command line, or
otherwise (see below).

Non-Alsa apps will generally want to use /dev/dsp, which you will probably
find is symlinked to /dev/dsp0. This will not work. If the app you want
to use allows it, you can configure it to use /dev/adsp0 as an alternative
device (XMMS can be configured to do this). Another solution is to
replace the symlink
/dev/dsp -> /dev/dsp0 with /dev/dsp -> /dev/adsp0 and that should get
playback working with all non-Alsa apps.
A more elegant solution is to use the CVS version of the 0.5.11 drivers,
which has some patches. This version supports mapping of the 2 internal
devices to different files in /dev for OSS emulation by means of a line in
/etc/modules.conf like -
options snd-pcm-oss snd_dsp_map=1 snd_adsp_map=0
To get this version from CVS, read the instructions for logging in to
anonymous CVS on the downloads page at alsa-project.org, and then execute
the following -
cvs -z3 - d:pserver:[EMAIL PROTECTED]:/cvsroot/alsa co
-rver-0-5-patches -P .
The above is all one line, and the final <space><dot> is essential!
This will download the complete source tree, and you can then compile the
drivers using the cvscompile script you will find there.
(The above information was all given to me by Takashi Iwai, to whom I am
most grateful).
I did all this, and playback of wav and mp3 files, and CD's works fine,
with any application. However, I have still not gotten capture to work at
all.
One final point; make sure you have unmuted and raised levels in the 2nd
mixer - use 'alsamixer -m1' to run it.
