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

It is recommended to set Digital Output Audio Format to Auto when the connected
receiver supports only the limited audio formats.
