All the mixer settings, their levels and the available word sizes and
sample rates seem all right, except for the max sample rates on the
first sound card.

However, the "1 card found" seems to contradict the rest of the
report. Also, it looks like the line that says '/dev/dsp:' should
say '/dev/mixer:' instead and the line that says '/dev/dsp0:'
should say '/dev/dsp:'. There is no /dev/dsp0 on my system, only:

crw-rw----    1 root     audio     14,   3 Aug 20  1999 /dev/dsp
crw-rw----    1 root     audio     14,  19 Aug 20  1999 /dev/dsp1
crw-rw----    1 root     audio     14,   0 Aug 20  1999 /dev/mixer
crw-rw----    1 root     audio     14,  16 Aug 20  1999 /dev/mixer1

Any ideas?

I can't reproduce the
"data format 10 (little endian short (16 bits)) not available on /dev/dsp"
error message, so I'm not sure what I was doing wrong yesterday. Today,
the first violin example in the manual doesn't give me an error message
anymore, but no sound either. I assume that could be related to the sound
card detection problem?
