Hey all, got a problem that maybe someone can help me with. I have a set of Logitech 5.1 speakers, not sure which set but they're about two years old. Due to space constraints I'm currently only using the 2 front speakers and the sub. The issue is with my Realtek on-board audio I don't have an option for 2.1. When I try and set it up the only options I have are 2 channel, 4 channel, 6 channel, 8 channel, and headset. I would like to be able to set it up such that the sub channel and line outs for the front speakers are seperated but I really don't know how to do this. Anyone have suggestions?
