polk magnifi to pc

[Niraj_5]

Dear team,
I recently bought the Polk Magnifi Mini soundbar to play it on my computer.
I was unable to connect it for surround sound , so i bought the Xonar DG sound card, and connected to it via Spdif port . But the sound is reduced a bit and i am unable to get the surround sound of 5.1 .

Do i need any extra cables ..
Do i need to change any settings in computer ...

My rig details =

4k Monitor LG 27UD68P
Sapphire R9 390 gfx card
Asus Xonar DG sound card
i5 6500

Please guide me how do i get the best sound of 5.1 , what extra acbles are required and what settings do i need to change in windows 10 ?

Thankyou.

You can't get surround sound out of that Polk. No rear speakers. At best it would be 3.1 It doesn't have center channel tweeter so I would guess that it's more like 2.1
It will accept a 5.1 signal but then converts it to 2.1
