Sound Drops Out From The Wireless Subwoofer

The JBL 3.1 soundbar comes with an external wireless subwoofer for the reproduction of low-frequency sounds. Once you pair the devices, you should be able to listen to and enjoy music from your subwoofer uninterrupted.

However, the subwoofer may appear interrupted after the connection and sound may begin to drop as a result. In case the sound drops, follow the steps outlined below to troubleshoot.

1.      Check For A Firmware Update

Turn off the subwoofer and use the soundbar’s remote to check the current firmware update. Press the sound control button that looks like a gear on the remote, once.

Then press and hold it for 20-30 seconds and check the numbers that follow “B” on the soundbar. You can then use the SmartThings app to perform the update or download the file if your Samsung soundbar has a USB port.

2.      Run A Speaker Test

Keeping the subwoofer off, press and hold the right button on the soundbar’s remote control for more than 10 seconds.

3.      Confirm The Subwoofer Is In Range

The subwoofer and soundbar should be about 33 feet. Check if there is a wall or any other obstacle between the two devices.

Also, check that no other device such as a Wi-Fi router that uses the same wireless frequency (2.4Ghz) is in range or near the soundbar. Such devices will cause interference resulting in sound interruption.

4.      Check All The Sources Connected To The Soundbar

Check all the signal sources such as TV, Blu-ray, or AV receiver. For instance, if the sound only drops out when you’re watching a TV then the issue is with the connections or the TV and not the subwoofer.
