No sound coming through your TV or soundbar after hooking up an Onn. streaming device is almost always a cable, port, or settings issue rather than a broken device. Work through these fixes from simplest to most advanced.

Check the Basics First

1. Confirm the TV isn’t muted and the volume is turned up — obvious, but it’s the most common culprit.

2. Check the HDMI cable and port. Unplug and firmly reconnect it at both ends, and try a different HDMI port on your TV if you have one available.

3. Try a different HDMI cable if you have a spare, to rule out a damaged cable.

4. Restart both devices. Unplug your Onn. device for 30 seconds and power cycle your TV as well.
