I just received the Allo Boss DAC in the mail, I connected it up with my RasPi 3, and connected the RasPi to my HDMI TV as a monitor. I am using Audacious as my media player, and the sound is coming out of the TV speakers. I have my amp connected via RCA plugs to the Boss. What do I need to do to get the sound from the TV back to the amp?
