how to ask question

Hello, Recently i bought HP ENVY J049-TX for music work purpose. 

Problem while recording music via Pioneer DJM 900 NXS mixer through soundforge software.

I use RCA to 3.5 mm jack to connect my laptop with my DJ mixer. 

While recording other background noises also gets recorded via my laptop mic along with music iam playing.

Since this laptop has one single input kindly help out, as what needs to be done, just to record music via my mixer. i have often disabled mic from control panel. but this isnt helpful
