There is no sound or the sound is
too low at maximum volume.
Check the volume control of your TV, and then check the volume control of the
external device (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV.
Check the cable connection between an external device and the TV, and then try cable
connection again.

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
, no sound is output with
Dolby
content.
It is recommended to set
Digital Output Audio Format
to
Auto
when the connected
receiver supports only the limited audio formats.
