No Master Output from Sample Decks

No Master Output from Sample Decks

First of all, hello everyone! I have been a reader of DJTT and it’s forums for quite some time, but due to the great community I never had to post a question myself. :slight_smile:
I am using a Traktor Audio 2 Interface and Traktor 2 Pro.
Up until now I never felt the need to use Decks C&D in Traktor for any reason, but now I want to experiment with some selfmade samples.
The problem I have is this: whenever I load a Sample and play it, the audio signal goes directly Channel B (Monitor Output is set to Channel B, Master Output is set to Channel A), whether I activate the monitoring option, or not. I can hear it through my headphones, but not through my speakers.
From what I have learned, this is probably caused by some setting I have overlooked, but after searching for hours I still cannot find it.
Thanks in advance!

e.o.

What’s the C & D routing set to in output preferences?

I am using the Internal Mixing Mode. So under Preferences>>Output Routing I only have to choose the Monitor Output and the Master Output.
I am/was under the impression, that any Deck would go through Master, as soon as it’s activated.
