I have a beatspill+ connected via an aux to rca cable into my tv. I know about the Roku private listening feature, but do not want to do that since I cannot screen mirror from my iPhone to the Roku and use the private listening feature at the same time. I need to get audio from my beatspill+ because my tv speakers don’t work anymore. I know the audio is working on the beatspill because when I switch input to cable I can hear the static noise. The beatspill Is connected to a white and red audio port in the back of the tv. I am not getting any audio played to my beatspill when I am using the Roku streaming stick+ connected via hdmi.
