Tony,
I have a SB Live Platinum 5.1 and I too have a problem with the front inputs (the signal is too weak), so to get a decent signal I have to plug the left and right outputs of my keyboard in the small line input on the card itself (in the back of the PC), using an adapter. No point in getting an expensive peace of gear if you have to use it like a cheap one, or is there a hidden sensitivity controller for the front inputs that I have missed?
