I'm on my 2nd Roku Ultra and no audio on my Onkyo Atmos receiver
I just purchased another Ultra because I have been troubleshooting the first one for two hours. Changed inputs, HDMI cables, ran the HDMI output cable from receiver to a second TV and still no sound on either of the Ultras. I can plug a Roku steaming stick in the same HDMI input port on the receiver and I get audio.
At wits end. I wanted the Ultra for Atmos capabilities.
