I'm sure this will work, but it is a lot easier to just open JAWS, then 
in the drop down menu go to "utilities", then "sound card".    "default" 
will probably be checked.   This means that whatever device windows sees 
as the default, JAWS will try and use.  Arrow down the list till you see 
the name of your on board sound card and select it.  Now JAWS will 
always use that sound card, no matter what other sound devices are 
installed.

I don't remember what version of JAWS added this feature, but it has 
been a few years.
