recording audio from a microphone

[rwcitek]

Thanks, Markus. Here's the output:

root@0[~]# rec -d /dev/dsp2 file.wav
Send break (control-c) to end recording
sox: Can't open input file '/dev/dsp2': No such device

root@0[~]#cat /proc/asound/cards
--- no soundcards ---

root@0[~]# ls -la /dev/dsp*
lrwxrwxrwx  1 root root       9 May  3 17:11 /dev/dsp -> /dev/dsp0
crw-rw-rw-  1 root audio 14,  3 Apr  5  2005 /dev/dsp0
crw-rw-rw-  1 root audio 14, 19 Apr  5  2005 /dev/dsp1
crw-rw-rw-  1 root audio 14, 35 Apr  5  2005 /dev/dsp2
crw-rw-rw-  1 root audio 14, 51 Apr  5  2005 /dev/dsp3

This seems to suggest that I have no sound card. Yet, the following worked just fine:

root@0[~]# play /KNOPPIX/opt/openoffice/share/gallery/sounds/top.wav
playing /KNOPPIX/opt/openoffice/share/gallery/sounds/top.wav

Thoughts? What else should I be looking for? Do I need to load a module or configure something?

Looks like you're using oss instead of alsa. It's usable too but alsa is more configurable and newer. See if via82cxxx_audio is in /etc/hotplug/blacklist.d/alsa-base and add it there if not. Also rmmod it so you can test alsaconf.
Alsa modules start with snd- and yours would be snd_via82xx. You can run alsaconf after blacklisting the oss module and rebooting.
You could also try the cheatcode alsa=via82xx
