Can I have audio through my TV's Speakers AND Wireless Headphones at the Same Time?

First, try this:

1. In your TV's settings, go to SOUND OUTPUT and change this to OPTICAL / EXTERNAL SPEAKER
2. Once there's sound coming out of the headphones, go back to SOUND OUTPUT and change this back to TV SPEAKER

OR one of the following:

• If you have a Soundbar or Stereo Receiver, you can get an Avantree transmitter that supports passthrough: Orbit, Oasis Plus, Opera, Medley 6018, HT5009, HT5006, Duet, or Quartet.
  • Connect the transmitter to the TV, and connect the soundbar/receiver to the transmitter. You'll get audio through both simultaneously.
• Use an Audio splitter/extractor to connect the TV to the transmitter and an external speaker
  • AUX: Avantree TR302
  • Optical: J-Tech splitter
  • HDMI ARC: HAX05
