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:ano...@cv...:/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.
