So, there are two ways to connect to RockSmith, you have a microphone sitting in-front of your Amplifier, or in-front of the guitar itself if you are using an acoustic. You also have their "Real-tone" cable which from what i hear doesn't work all that well and that's it. I want to know if it would be possible to take the output of an amplifier's headphone port, and then plug that into a computers input port which is typically used for a microphone or any other input device. I am sure its possible, but for some reason it does not work for me, do i have to have the amplifier turned up high, or is there something else i am forgetting? I would perfer to use the "line out" of my amp because the way my setup is, i have to turn the amp up high for it to work, and even then the game seems to have a hard time recognizing it. Any help is appreciated.
