That was one of the many programs I wrote too.  Ah, the days of C coding
on DOS....  Good times, but I'm glad they're gone.  Today just do this:

On CentOS 5.6 go into System > Preferences > Sound, click on the "System

vulnerable members, treats its forests and lands with respect,
then it will prosper and not decline."
