If there’s no sound coming from your sound bar even though it’s connected to your TV, first check that your sound bar, TV, and set-top box are not muted and that the volume is turned up.
If the volume settings are correct, check the cables (HDMI or optical) and make sure your TV’s audio output is set correctly.
Why Is There No Sound from the Sound Bar?
- Your sound bar, TV, or connected set-top box may be muted or set to a very low volume.
- The HDMI or optical cable connecting the TV, sound bar, or set top box may be loose or disconnected.
- When using an HDMI cable, make sure it's plugged into an HDMI (eARC/ARC) port instead of a standard HDMI port.
- Your TV’s audio output may be set to the internal speakers or another device instead of your sound bar.
- If you are using a WOW Dongle for a wireless connection, there may be an issue with the dongle’s power or connection port.
How to Fix Sound Bar Audio Issues
Check the Volume and Mute Settings on Each Device
- Use your sound bar remote or the buttons on the sound bar to turn up the volume.
- Use your TV and set-top box remotes to make sure the volume is turned up and not muted on each device.
Check the Cable Connections Between Devices
- Make sure the cables connecting your TV, set-top box, and sound bar are plugged in correctly.
- Check that the HDMI or optical cable is fully inserted into both devices. If it is loose or unplugged, reconnect it firmly.

Test Your Sound Bar with Another Device
- If your sound bar has no sound when connected to your TV or set-top box, try connecting it to another device—such as a smartphone or tablet—via Bluetooth.
If your sound bar successfully connects to your smartphone and plays sound normally, your sound bar is working properly, and the issue is likely related to your TV's settings or cables.
Check the WOW Dongle Connection (If Applicable)
- If you are using a WOW Dongle with your TV or projector, make sure the dongle is powered on.
- The dongle must be connected to your TV’s HDMI ARC port, and your TV’s audio output should be set to [HDMI/ARC].
