I just bought a Creative T3150W with 2 front speakers and one sub. The speakers requires that the front speakers are connected to the sub and the sub connected to my computer. If I do that Realtek HD Audio sees them as one speaker wich results in be getting mono sound. I can connect the front speakers and the sub separately but then I cant regulate the volume on my front speakers and with every volume option on my computer at max, I can barely hear the front speakers, but I have stereo and my sub is working fine at that point. Thanks!
