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.

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.
HDMI (eARC) is connected, and there is no sound.
Check whether
Digital Output Audio Format
is set to
Pass-Through
.
If a sound bar or A/V receiver that does not support
Dolby
is used and
Pass-Through
is selected, there is no
sound when a
Dolby
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 sound bar or A/V receiver.
