Dragon Naturally Speaking (v.6) issue: "The speech engine was unable to open the audio channel"

System is the following:

Windows 7 Home Premium x64
HP G72 Notebook PC
Realtek High-Definition Audio

Software is:

Dragon Naturally Speaking 6.0

Issue is that when selecting the "Prepare User for Dictation" option in the "NaturallySpeaking" drop-down and hitting "Go" on the dictation screen that appears - it displays the error "The speech engine was unable to open the audio channel"  The program doesn't appear to have any internal options to deal directly with audio devices that I can find.

What could be the issue?  All devices/drivers are working properly on the system and enabled.

Hi, looks like this is the problem>The speech engine was unable to open the audio channel<~> audio channel
Your audio>>Realtek High-Definition Audio<< probably not supported in the native format and settings  like it's using speaker fill, you may have to adjust the audio High-def aspect and put it to analog
Sorry I cant actually show this since I'm on windows 7 professional
But take a look in your spekaer configuration settings>enhancement
