My lack of a "sound' understanding

[J]

Okay, I am a complete noob, so have patience. I don't know all the proper
nomenclature as of yet.

I installed, then reinstalled and re-reinstalled 5.1 on a dell gx1 with
the crystal sound chip with little
difficulty up until I went to do the file sharing experience with Samba
and the sound thing. For now I just want to get this sound problem
understood. Now according to the manual in order to load the sound device
I can either kldload or configure a kernal. I understand this. What I
don't understand are two things at least, when I kldload, exactly where do
I need to be to do this? In what directory? I mean, when I bring up a
terminal and punch in kldload snd,or snd0 it says "can't load snd, no such
file or directory". I did install the src/sys files. I understand that 5.x
is somewhat different than the other distros which I interpret to mean
that this should be somewhat friendlier.

The other thing I seem to get conflicting messages about is if I can
actually just add the "device pcm" bsd/docs 16.2 to the existing kernal or
do I have to totally rebuild it?  Or is this one in the same?

I don't mind reading the manual, it just seems as if I am overlooking
something essential. So maybe if you can help me find the basics I am
missing?

Thanks
