HDMI (eARC/ARC) is connected, and there is no sound.
Check whether Digital Output Audio Format is set to Pass-through.
If a soundbar or A/V receiver that does not support Dolby Digital+ is used and Pass-through is selected, there is no
sound when a Dolby Digital+ source is received.
It is recommended to set Digital Output Audio Format to Auto if only limited audio format is supported depending
on the performance of the connected soundbar or A/V receiver.

The sound is interrupted.
Sound quality may become affected if the wireless router is close to the Bluetooth speaker. Place the Bluetooth
speaker as close as possible to the TV without obstacle between them. Do not place the wireless router close to the
Bluetooth speaker body.
To minimise interruptions, we recommend a wireless access point that uses a 5 GHz frequency. 5 GHz may not be
available depending on the model.
When the symptom persists, it is recommended to use wired connection such as HDMI (eARC/ARC) and Optical.
