Issue with .ebs2 file and sounds on Windows 7 with High Definition Audio Device as audio driver

[David McFarlane]

Adam,

Come to think of it, you might look at your sound codecs.  Try running 
the Codec Config and Sound Tester utilities on your subject running 
stations, using your sound files.

If your subject running stations do not have the codec to run your sound 
files, then you will either have to add the codec to those computers, or 
redo your sound files to use a codec that those computers already have.

Regards,
