Yes, 5X is what? 14dB? That would be very noticeable.5X gain is a LOT for most hi-fi line amps. Why is it "signal does not get amplified. At least not noticeable" for you?
It would not be the first time that such a board is shipped with different values than the documentation says. That said, it would be a no-brainer to check the resistor values, they seem clear on the picture, with a cheap meter.
With a magnifying glass (we all have one, right ? ;-) the code can be read off in 10 seconds.
