GDog 07

I have an Alesis Multimix 4 USB FX with 4 channels 2 stereo and 2 mono (L/R). I am trying to record 2 different mics at the same time and use a separate track for each but when selecting the input Cakewalk only recognizes 1 channel. I tried using ASIO4ALL but it didn't change anything. I looked everywhere and havent found a solution please help
