Rocksmith remastered audio help

[Hippy22]

I am new to RS and i am trying to setup RS to work with CDLC and with my audio interface i have a  Focusrite  clarett 2 pre 4 outputs and two inputs and a mic output, so far i have download RS 2014 remastered and Cherub Rock, I thought i would start with getting the Sound working first before working on getting cdlc to work, so i have downloaded RS Asio 0.6.1. some of the setting in the RS ASIO are [Asio.Output] Driver=Focusrite USB ASIO /  BaseChannel=0  / [Asio.Input.0] Driver=Focusrite USB ASIO Channel=0, when i run Rocksmith the sound out lags a lot and i cannot control the sound levels using the audio interface volume knob. my audio interface is connect by USB to my pc and i have one speaker going to line out 3.
