I haven't been able to find the answer to this but when I plug in the official UBISoft Realtone cable to my PS3 running Rocksmith remastered and try to select the Realtone cable option I get a message saying it is not connected when it is plugged into my fender stratocaster and no indication of sound. When I choose the microphone option the realtone cable picks up the sound when plugged into the guitar and it seems to work that way. Is there a way to fix this so I can use it with the realtone option? wouldn't it be better to be able to use the realtone cable option? When I plug the cable into my PC and the guitar it also shows sound from the microphone test function.Thanks

UPDATE: The brand new cable was bad. I got a new cable and that solved it.
