An update for those interested and for those that may encounter this problem at a later date.
I found
this web site and followed the instructions.
They did not work for me so then I downloaded the windows xp service pack. All the new drivers are located in this pack and rectified the problem.
Newer releases of win xp have the drivers as well
Further, I am told that DEVLDR is only required for DOS related sound on older games, so it is not really needed.
