Question

When I plug in USB speakers, the Dolby Home Theatre is not activated.  Does it only work with the internal speakers and speakers using a 3.5mm jack plug?

 

Are there any settings in control panel / sound ?

Answer

The Dolby Home Theater technology is dependent upon the Sound Device(Realtek or Conexant).

 

External USB Speakers might not be a normal speakers but an External Sound Device and not just a passive speaker function that relies upon the sound chip in the system.

 

    Verify this by opening Sound properties window.

    Control Panel / Hardware and Sound / Sound

    It should  look like this, under Playback Tab

If the USB speaker is being detected as another sound device, It will appear here.

If this is the case, the Dolby feature / function will not be available through this device.
