I've not noticed that, but I'll take your word for it.  I have a
snd-ali5451 and a snd-usb-audio both working fine, with mixing and so
on.  However, I don't use KDE.  I added a line

Exec "Restoring Sound" alsactl restore

to /System/Settings/BootScripts/Graphic and I think that's all.

Does lsmod show the right snd modules?
If not, can you modprobe snd-via82xx OK?
What is in the file /proc/asound/cards?

I'm puzzled by the /dev/dsp report.  It shouldn't exist without ALSA.
Does dd if=/dev/random of=/dev/dsp count=2 produce noise?
What is ls -l /dev/dsp (and ls -l $(readlink /dev/dsp) too)?

I'm not sure I've ever used alsaconf.  Does it work for anyone?

Hope that helps,
