Have you checked if the chain is perfectly straight when using the middle cog of the cassette? I could only have a straight chain in 8th/9th gear. If I moved the chainring any closer to the frame, the chain would rub the frame in 1st gear.
I have no frame rub, the chain does line up in center. I get noise from some deflection from the chain in the lowest gear on the cassette, it goes away when I shift up to the next gear.
