Surround Sound not working on ION Motherboard

[panusha]

Hello everybody!

I have just installed OpenELEC. So far, everything is working fine except for the surround sound. This is my hardware setup:

- IONITX F-E Motherboard
- Creative Inspire P5800 Speakers

I extract video through HDMI (everything working fine on this side). For the audio, I'm usin analog 3.5 mm mini-jack cables through the integrated motherboard audio card and into to the speakers. I mean the classic three color 3.5mm audio cables, like this:



The thing is, no matter the configuration options I choose, I only obtain stereo sound (rear speakers don't work). Prior to installing OpenELEC, I was using Windows XP on the same hardware and everything was working fine, so I suppose this is a driver / software issue. Could you give some guidance on how to fix it?

Thank you very much,
