How to Reset Sonos Subwoofer? Sonos continues to deliver some of the best multi-room speakers on the market. It also makes excellent wireless subwoofers, with the Sonos Sub (Gen 3) being the current-best option. As performant and stylish as it is, it isn’t without its problems, for which users may have to reset their Sonos subwoofer.
The Sonos Sub isn’t certainly immune to software and connectivity bugs, and like everything else these days, all it needs is a soft or hard reset. Whether you have a 1st, 2nd, or 3rd-gen Sonos Sub, we’ll walk you through the process of resetting it.
How to Reset Sonos Subwoofer
The term “reset” can mean two different things. It can be a soft reset or a reboot, which only resolves temporary errors and minor processing glitches.
A hard reset or a factory reset, on the other hand, not only wipes saved system configuration but also deletes all user registration information from a device. Performing a hard reset means restoring your device to its original factory state, after which you’ll need to reconfigure it like the first time.
So if your Sonos subwoofer has suddenly stopped working, give it a reboot first. If that doesn’t work, only then consider initiating a hard reset.
Soft Reset (Reboot) Your Sonos Sub
It’s relatively straightforward to reboot your Sonos Sub. Here’s what you have to do:
- First, gently unplug the power cord from the back of your Sonos Sub or the AC outlet.
- Wait 10-15 seconds for the subwoofer to power off and discharge completely.
- Now replug the power cord back into your Sonos Sub or the power outlet.
- Give your subwoofer a minute or two to power on and connect to your other Sonos products.
For most issues, a soft reset or reboot should do the trick. But if it doesn’t, you’ll have to go with a factory reset.
Factory Reset Your Sonos Sub
Some problems persist even after a reboot. In such cases, you have no other choice but to perform a hard reset on your Sonos subwoofer. As scary as it may sound, the process is actually pretty easy and safe to follow.
- Start with powering off your Sonos Sub by unplugging it from the power outlet. Make sure the LED indicator isn’t glowing or blinking.
- Now push and hold down the Join button (?? or ∞) on the Sonos Sub while replugging the power cord.
- Continue holding the Join button until the LED starts blinking white and orange.
The LED light on your Sonos Sub will flash green when the factory reset is complete. Since the subwoofer deregisters from the rest of your Sonos system, you’ll need to add it again from the Sonos mobile app. Simply go to Settings > System, tap Add Product, and follow the onscreen instructions to set up and configure your Sonos Sub.
What if Resetting doesn’t Fix Your Sonos Sub?
A soft or hard reset usually fixes all the Sonos Sub problems most of the time. But if you’re still encountering disconnection, no output, or other issues, here are a few things you can try besides resetting:
- If you’ve recently updated the Sonos app, it may have caused the subwoofer to not properly function. Resetting the app may fix the problem.
- Simply open the Sonos mobile app, go to the Settings > App Preferences menu, then tap the Reset App
- On Windows or Mac, launch the Sonos app, click Help at the top of the app window, and select Reset Controller.
- Your Sonos Sub may be running on an older firmware version, resulting in it not working with your other Sonos devices. Updating its firmware should resolve such issues.
- Go to Settings > System > System Updates in the Sonos mobile app and tap Check for Updates.
- If you’re on a PC, open the Manage (Windows) or Sonos (macOS) tab and click Check for Updates.
- If your subwoofer connects to the rest of your Sonos system over Wi-Fi, consider wiring it to your home router using an Ethernet You can also try moving it closer to your router and see whether that fixes the connectivity issue.
It may be that your Sub is too far from the router, which is why it can’t maintain a stable connection.
- Check if the LED indicator on your Sonos Sub is flashing green. If it doesn’t, make sure to plug the power cord directly into the AC outlet. Avoid using extension power cords or power strips, as they may not be able to carry enough power to the subwoofer.
