I am having a lot of trouble getting multichannel audio to work. I am trying to create 5.1 surround sound in my game. I import the 5.1 files with the proper naming conventions (as defined in the documentation), and it creates a single surround asset like it should. The problem is, when I play it, it only plays out of channels 1 and 2. I cannot get audio to play out of the other channels.
Note: I have my audio interface connected and set as the output device for my computer, but cannot find a place to choose where to output audio in the UE4 preferences. Maybe this is the problem?
