Slim Phatty/Duet Help

I just bought a slim phatty and haven’t been able to get any sound out of it.

I can hear it if i connect headphones directly into the SP or by connecting the SP straight into my KRKs.

I have the SP’s audio output going into IN-1 of a Duet. From there, i use ableton live, with 1 ext instrument set up (MIDI To: Slim Phatty/CH 1 / Audio From ch 1). The SP’s usb is connected as well.

It recognizes the midi notes coming from my Alesis Q49. & the SP recognizes the midi as well. yet still no sound.

Can anyone possibly help me out? I honestly don’t know what i’m doing wrong here. :frowning:

Is the output on/off button on the slimphatty turned on?
