No audio on AUX INPUT - Ripsaw (OBS/XSplit)

Hey, all.

I'm trying to figure out how to deal with Ripsaw Audio Inputs. I was not able to find how to select, as audio source, either AUX or MIC inputs insite OBS and/or XSplit. It looks that these inputs were not detected as a hardware ones. I can select my soundcard inputs and laptop mic/input but unable to find how to select the AUX input (or MIC) as audio source.

Ripsaw User Guide does not say nothing about that.
