Hello,
<para>To use your sound device, you will need to load the proper

+ Loading the device driver may be accomplished in one of two ways.
The easiest way is to simply load a kernel module for your sound
card with &man.kldload.8; which can either be done from the
command line:</para>
I think you had to put that later just after
<para>These examples are for a Creative &soundblaster; Live! sound
card. Other available loadable sound modules are listed in
<filename>/boot/defaults/loader.conf</filename>.</para>
cause in your case you "break" the "This may be accomplished in one of
two ways." statement and it could be confusing for the reader.
"snd_driver" must also be tagged.
