I usually used cat <anyfile> >dev/dsp. I found a short text file
(e.g. /etc/fstab) gave a short rasp of white noise, which is all you
want to know. If you use a long one, it will keep going.

What have you in modules.conf? Most soundcards have suggested lines in
the kernel ~/Documentation/sound/yourcard. I presume alsa has a similar
resource, but after watching the continual stream of buggered sound
installations appearing as topics on this list with 'alsa' in them
somewhere, I'm tempted to break ranks on that and stick with OSS
