Remote has 2 Sets of Volume Buttons

[DevourDarkness]

Hi, I know this is not exactly the right sort of forum but I thought someone might know why the remote that came with my 5.1 speakers has 2 volume up and volume down buttons. But pressing either 2 of the volume up buttons just does the same thing, increase the volume on the display by one, and same for volume down.

So why does it have 2 sets? Is it some special feature or something to do with surround? Or even just for looks lol? Pic:

As a guess, I'd say that one set is for the front pair of speakers and the other is for the rear speakers. It could also be that one is actually a front-to-rear fader and the other is a left-right balance control.

What brand and model are the speakers?

In Device Manager>>Sound, what do you see highlighted under "Set a playback device..." and what do you see selected when you press "Configure"? The fact that both sets of buttons do the exact same thing makes me think that Windows isn't sure what kind of speaker configuration you have.

Did the speakers come with any software? If so, is it properly installed?

Its not about Windows. Everything in terms of software is set up correctly. It's the fact that the volume display on the subwoofer is affected equally by each button and I hear no difference between pressing one and another.
