Thanks for the reply Lowell (or is it Gilbert). Do you know of any
additional information on "devfs" apart from the man pages, since I
browsed the man page and it didn't make all that much sense for a new
FreeBSD user. If all else fails I'll fold back to an earlier release.

I have tried to configure the settings of KDE in the control centre
under its sound system IO dialog to set the custom device to
"/dev/dsp0.0" then, "/dev/dsp0.1" and tried to test one of the KDE
default notification sound, with no success.

This is one of the places where you suffer from running an "early
adopters" release rather than one intended for production use -- the
documentation for handling sound doesn't cover 5.x nearly as well as
4.x.  Read the manual for devfs and whatever related bits you can
find.  [Sorry I can't be more explicit, but I don't run 5.x yet
myself, and I have limited documentation access from the screen I'm
currently working on.]

The trick will definitely be how to get devfs to create the nodes,
because the kernel sure seems to be recognizing the sound chip.

Also note that your sound sound subsystem might be getting recognized
as device 1 rather than device 0, so in looking for the device nodes,
do an (e.g.) "ls /dev/dsp*".

Good luck.
