Blender Setup - No Sound


Hi all

Wondering if any is kind enough to help.

Im having issues getting any sound from my blender. I have drivers installed and can see it is connected via the app. Using Win 10 and Ableton 11. Trying to get some Korg Volcas to 'sound' but nothing. In fact since buying it I have only ever been able to use it via headphones.

In truth I dont understand this at all. Struggling with connections for a wide range of kit.

So how does anyone using this kit for ableton and external synths get sound in ableton?
