If you’re like many Sonos owners, you’ve been frustrated trying to figure out why your Sonos sub isn’t producing any sound.

Don’t worry; you’re not alone! This article will explore why your Sonos Sub might be connected but not producing sound and how to fix it.

Why is my Sonos sub connected but no sound?

Short Answer: Your Sonos Sub is connected but has no sound for different reasons like cables are not connected properly, error in volume, wrong settings and various miscellaneous factors.

Reason 1: Physical Connections of your Sub

The first step is to make sure that the Sub is physically connected correctly.

For example, ensure that the power cable is plugged into the back of the Sub and that the Sub is connected to your home Wi-Fi network via an Ethernet cable.

If the connections are correct and the Sub is still not producing sound, proceed to the next step.

Reason 2: Volume-related problems

The next step is to check the Sub’s volume level. You can do this in the Sonos app, which allows you to adjust the volume level of each speaker individually.

First, ensure that the Sub’s volume is not set to the lowest level. If the book is not the issue, proceed to the next step.

Reason 3: Check your Settings

The next step is to check the settings of the Sub. First, ensure the Sub is configured to the correct locations in the Sonos app.

For example, check that the ‘Bass Management‘ option is turned on, as this will ensure that the Sub receives the low-frequency signals.

Additionally, provide that the ‘Bass Level‘ setting is set to the right level. If the settings are correct and the Sub is still not producing sound, proceed to the next step.

Reason 4: Check for Obstructions in your surroundings

The next step is to check for any physical obstructions blocking the sound from the Sub.

First, ensure that no objects are blocking the Sub’s good path, such as furniture or walls. If there are no obstructions and the Sub is still not producing sound, proceed to the next step.

Reason 5: Time for Factory Reset

The last step is to perform a factory reset on the Sub. This will reset all the settings of the Sub back to their default state.

To do this, press and hold the mute button on the back of the Sub for 10 seconds. Once the reset is complete, the Sub should be producing sound again.
