Is there a "common theme" of the error messages? Sometimes the error
messages produced by "amixer" are more helpful.
Another basic thing to check is if the device nodes are there and have
the proper permissions and ownerships:
$ ls -l /dev/{mixer,dsp,sequencer*}
crw-rw---- 1 root audio 14, 3 2007-01-28 00:21 /dev/dsp
crw-rw---- 1 root audio 14, 0 2007-01-28 00:21 /dev/mixer
crw-rw---- 1 root audio 14, 1 2007-01-28 00:21 /dev/sequencer
crw-rw---- 1 root audio 14, 8 2007-01-28 00:21 /dev/sequencer2
$ ls -l /dev/snd
total 0
crw-rw---- 1 root audio 116, 0 2007-01-28 00:21 controlC0
crw-rw---- 1 root audio 116, 24 2007-01-28 00:21 pcmC0D0c
crw-rw---- 1 root audio 116, 16 2007-01-28 00:21 pcmC0D0p
crw-rw---- 1 root audio 116, 1 2007-01-28 00:21 seq
crw-rw---- 1 root audio 116, 33 2007-01-28 00:21 timer
The output of dmesg right after boot might contain some helpful info;
you could try something like
dmesg | egrep -i 'sound|alsa|snd|intel'

First I would check if booting the newest Knoppix version gives you
sound.
