I have a home cinema system (LG BH7430P) and want to have them as my PC speakers by connecting them through an optical cable from my soundcard (Asus Xonar DGX) to the av receiver. However when i do this no sound comes out, it comes up on my computer that an optical cable has been connected and i use as default playback but no sound comes through.

I have linked the speakers up with my ps3 via optical and it works fine so i can't seen it been a fault with my receiver.

if anyone knows why its not working or have any suggestions it would be very appreciated.
