Alsa thinks you have sound devices or it wouldn't play.  Go te the
console again and type 
aplay -l
This should list all the devices that alsa is aware of.  If you have
cards, it is just a matter of getting them recognized by pulse.

Pulse is not aware that you have any sound devices.  Install the
package pavucontrol.  Start the app, and go to the last tab.  It allows
you to manage the devices there.  You will probably have to turn them
on, and make the correct device the default.

Is there any way to tell what sound mechanism KDE is using to play?
Try opening a term in KDE and doing the 
aplay another_brick_in_the_wall_part_2.wav
again.  Does it play?  

Was your system a new install, or an upgrade?  If it was an install,
did you use a KDE live CD to install, or a DVD?  Have you installed
another low level sound library like OSS4?  I ask because this is so
unusual.  If we can't get this working, it would be great if you would
open a bugzilla for this and put in all the above answers in order to
get it fixed.
