Quick Fixes to Restore Sound

The following are basic tweaks that you can do to eliminate common factors that may be preventing your speaker to omit sound as intended.

Try these simple solutions for a Bose TV speaker without sound:

1. Inspect connections and firmly push/twist cables into ports

Lose connections could be the main reason why you don’t hear any sound coming from your speaker. Thus, thoroughly inspect cable connections between your speaker and television.

Inspecting physical connections can help deal with no sound problems on a Bose TV speaker in the following ways:

Loose or disconnected cables. If a cable is loose or disconnected, it can prevent sound from being transmitted from the soundbar to the TV. Check the seating of all cables at both ends to make sure they are properly connected.
Incorrect cable connections. Make sure that the cables are connected to the correct ports on the soundbar and TV. For example, the HDMI cable should be connected to the HDMI OUT port on the soundbar and the HDMI IN port on the TV.
Damaged cables. Inspect the cables for any signs of damage, such as kinks, cuts, or fraying. If a cable is damaged, it will need to be replaced.

To inspect the physical connections on a Bose TV speaker:

Disconnect all cables from the soundbar and TV.
Inspect the cables for any signs of damage. If a cable is damaged, replace it.
Connect the cables to the correct ports on the soundbar and TV.
Make sure that all cables are properly seated.
Turn on the soundbar and TV.

Here are some additional tips for inspecting physical connections:

Use a flashlight to inspect the connections in hard-to-see areas.
Try wiggling the cables slightly to see if they are loose.
If you are using an HDMI cable, try connecting it to a different HDMI port on the TV.
If you have multiple devices connected to the soundbar, try disconnecting them one at a time to see if that resolves the issue.

If you have inspected all of the physical connections and you are still having no sound problems, it is possible that there is a problem with the soundbar itself. In this case, you may try some other ways to fix the problem.

If you are using HDMI ARC to connect your Bose TV speaker to your TV, but you are not getting any sound, it is possible that there is a problem with the HDMI cable itself. Trying a different HDMI cable, especially a high-speed HDMI cable, can help to resolve the issue.
