when setting up “control your tv” music is not clear.. when i skip this step the picture is clear but the voices sound like alvin and the chipmunks, very cluttered." I disconnect the unit and started over with the same results. I return the first Roku Ultra HDR but this one is doing the same thing. My TV plays fine on other channels with DIRECTV or Blue-Ray player.
Your forum profile indicates you have a Roku 1 Model 2710 - not an Ultra.
What is your model # and firmware version? (Settings/System/About).
If its a 2710, are you connected via HDMI or Composite?
