Ensure the TV's volume is not set to zero or muted.
Verify that the external speaker is powered on.
Check whether the speaker is connected to the TV wirelessly or via a cable, and select the appropriate setting on your TV.
If you have an external device, such as a soundbar, connected to the TV, make sure to check the volume settings on the device as well.
If the cable connecting the TV to the external device is damaged, it may cause problems with audio or video.
