A:Answer Hi Timlallen,
Thanks for your inquiry. For the A80J, the TV cannot output sound from both the headphones or Bluetooth audio device and the TV speakers at the same time. Doing this will cancel the TV speakers from being used.
Sound can be output from both an audio system connected to the TV and the TV speakers at the same time by satisfying the following conditions.
- Connecting the TV and audio system using a digital optical cable
- Setting [Digital audio out] to [PCM]
By connecting your headphones to the TV headphone jack (3.5 mm stereo mini jack) and your Soundbar or Receiver to the DIGITAL AUDIO OUT port, it will output sound from both the headphones and a Soundbar or Receiver. There are also Sony RF (radio Frequency) wireless headset options such as the Sony WH-L600 or WH-RF400 that uses its own transmitter connected to the headphone jack on your TV as well as optical digital output (WH-L600) of the TV.
For more information on how to listen to your TV through headphones and the TV speakers, soundbar, or another audio device at the same time, please check the link below.
