RCA to 3.5mm not working

[bigbuddy]

Hi guys, How do i connect f&d f6000 5.1 to intel dh87rl motherboard? The motherboard specification says 10.2, So ithink 5.1 must work. I purchased 3 RCA to 3.5mm cables and connected them correctly, But when i do a sound test in realtek HD manager with 5.1 speaker setting only my front speakers seems to work.. Other 3 are not working. How do i get 5.1 surround sound in my pc? I tried updating my audio driver to current version but still not working..

Try right click volume control icon at bottom right of taskbar > Playback devices > Select the sound card > Right click > Configure speakers > set 5.1.
