I have a SR5300 hooked up to a soundstorm mobo via an optical lead. Surround sound works a treat when playing DVD's on my PC - but that's were it ends. I'm only able to play MP3's in stereo mode and not PL2 - although the plugin that I use for Winamp has gotten around this. Games also only output in two channels. I have both PES3 and FarCry. I have set the options in FarCry to 5.1 but still no joy. I have done the speaker settings thing in the NVidia mixer wizard and set it to digital. Any ideas on how I can get surround sound in MP3's (short of using a plugin) and games????
