Why does Intelli-Site require a sound card?

Intelli-Site was designed to play sounds and use Text-to-Speech annunciation; it is linked with libraries that provide these sound capabilities.  These libraries require a sound card to work properly.  Any computer with a Workstation or ServerStation installation must have a working sound card.

Windows 7 will disable the sound card if there is nothing plugged into it.  This will cause problems for the sound libraries we use.  Therefore, you must have some sort of sound device plugged into the sound card on Windows 7 or Windows 2008 R2.  Earphones work.
