Newb Deck Problem
Deck B is loading and playing, but I can’t hear it.
What is up?
What’s your controller, software and soundcard?
Fader -->?
Traktor 1.2.7
M-Audio Axiom 49 via USB
Internal sound card on computer
you need to have the internal mixer used in traktor if your just using the internal soundcard. i believe.
i had this same issue when i would go from my audio 8 to the internal. i can’t remember the steps, but it was a audio setting within the configuration. im sorry if i not really helping with a step by step, but i know it has to do with the audio setup and internal mixer.
also make sure you arent in cruise mode. i had cruise on one night while laying drunk in my bed 
and the next day couldnt figure out why my mixer wasnt working. cruise man cruise.
