Go into your sound settings and set the speakers in the computer as the default device

Figured it out. The desktop defaults to the computer speakers when VarAC opens and the laptop defaults to the virtual USB port upon starting. Thanks for your response.

OK....strange. I switched to my desk top computer ( Windows 11 PC ) and it works as it should. VarAC warble goes thru radio and narration goes thru computer speakers. What gives ?
