Question / Help (HELP) Audio (Nightbot) Problem

[Abroxas]

1. Hey guys, I have a small Problem with obs and nightbot.
   
   I want to stream Music to YouTube with the help of nightbot and obs. it worked perfectly at first but all of a sudden obs stops recognizing my Audio Input everytime nightbot Switches to the next Sound. I can still hear the Music from my Speaker or headphones but OBS just doenst. I tried to reinstall OBS and it still wont work.
   
   I tried it on my Laptop and to my surprise it works just fine. Unfortunately I Need my Laptop for some other Things and it really bothers me that it wont work on my PC. It worked the first time so why does OBS loses the Audio Output Signal once nightbot Switches to a new Sound?
   
   I hope one of you guys can help me...
