  • If your transmitter base has an output switch, make sure it's set to the correctly (for example, if you used an AUX cable, make sure it's set to AUX)
  • Make sure there's nothing in your TV's HDMI ARC (it could be interfering)
  • Unplug and Plug the audio cable from the transmitter
  • Start your Netflix / Amazon Prime Program first, then change output format on your TV to PCM
