Thanks so much haha. Yeah, I unfortunately opted to buy a premade pc since it was ~the same price as building my own (this was during the bitcoin GPU rush where GTX 1080 prices were absurd). It came with a ton of nonsense software that I left alone for the most part, this is likely one of them then. 

7-Nahimic is an audio software, probably an audio loop that is probably meant for streaming or something along those lines. The BenQ is your monitor, as HDMI or Displayport is able to transmit audio code though the cable to the monitor.
 
Glad that the problem was resolved though.

have you tried setting the Realtek as your default audio output? Sometimes the GPU would take priority.
 
Usually disable or turn off any Nvidia outputs.
 

 
 
sometimes a menu will show up like this when right clicking, set up as default device for which device you are trying to output on.
