How to Control Sound for My New Speakers

I have a new Companion® 5 multimedia speaker system connected to my Windows 7 pc. Installation was simple and no issues. System plays great. However, instead of the usual 'jack-type' connection these speakers connect via USB. I think this is the reason I cannot utilize the Realtek HD Audio Manager to fine-tune my sound. When I make it the default the speakers have no sound.

Is there a way to get these speakers and the Realtek manager to communicate?

1. A configuration tweak or registry mod?

2. Maybe a USB-to-3.5mm adapter?

3. A Realtek Manager-type s/w that 'does' USB-connected speakers?

-thx

The web is full of blogs on this subject and the ones I looked at didn't provide what i call a universal solution.

Click on your speakers and then select Properties in Sound. In the Custom tab, is "digital output only" selected? if so, deselect it.

Does that help?

wither 2 - thank you so much for your reply. Unfortunately, as per the image, there is no 'Custom' tab. I also poked around and could not find a 'digital ouput only' setting.

My apologies. Look in the Properties of the Realtek Speakers selection.

No custom tab there ...

Have you tried any of the methods from the manual here-

Resolved by running a 3.5mm cable from the pc audio line-out to the line-in/aux of the Bose Controller.
