If you are using an external device, check the device’s audio output option.
For example, you may need to change your cable box’s audio option to HDMI if the box
connected to your TV is using an HDMI cable.
To listen to computer sound, connect an external speaker to the computer’s audio
output connector.
If your TV has a headphone jack, make sure there is nothing plugged into it.
Reboot the connected device by disconnecting and then reconnecting the device’s
power cable.
With a set-top box or cable box, check the cable connection and reboot the external
device. When the symptom persists, contact your service provider.
No sound is heard.
Check whether Digital Output Audio Format is set to Pass-Through.
If you select the Pass-Through option to use an AV receiver that does not support
Dolby Digital+, no sound is output with Dolby Digital+ content.
It is recommended to set Digital Output Audio Format to Auto when the connected
receiver supports only the limited audio formats.
