Real cable problems! (Rocksmith)

By the way, I encountered the same problem today, I thought the cable was covered, but now I see that the reason is different. In what? - That's the main question. The problem is not the cable.

This is a common problem. Try turning off everything that can play sound (programs).

x box 360 original cable, but the game is pirated, practically does not fix the guitar, i.e. there is animation in the speakers, but the slider itself does not move (in calibration), but if you remove the cord and touch it with your finger, it starts to react ....
broke my head already, please help
