Sonos Won’t Connect/Keeps Disconnecting From TV

The beauty of having a separate speaker for your TV is that you typically have better volume, more sound clarity, and a wider span of sound adjustment. What then do you do if your Sonos won’t connect or keeps disconnecting from your TV?

If your Sonos speaker won’t connect to your TV, one common issue could be an incompatible or faulty cable connection. Most Sonos speakers connect via an optical or HDMI-ARC cable, and using the wrong type of cable or a damaged one can result in connectivity issues. To resolve this, first identify the type of cable your Sonos and TV require. Ensure that you’re using the correct and undamaged cable, and plug it securely into the appropriate ports on both the TV and Sonos speaker. Check to see if this solves the connectivity problem.

Another reason why your Sonos may not connect to your TV could be due to software-related issues. Outdated firmware on either the TV or the Sonos speaker can lead to compatibility problems. To resolve this, check for software updates for both devices. For the Sonos speaker, open the Sonos app and navigate to “Settings” and then “System Updates” to check for updates. For your TV, go to the settings menu and look for an update option, typically under “System” or “About.”

Wi-Fi interference is another possible reason for connectivity issues between your Sonos speaker and TV. Other devices or networks can interfere with the Wi-Fi signal, causing disruptions in the connection. To fix this, try changing the Wi-Fi channel on your router to a less crowded one, or move other electronic devices away from the Sonos speaker and the TV. You can also try connecting your Sonos speaker to the router using an Ethernet cable for a more stable connection.

When you are using a Sonos speaker, the purpose of that speaker is to enhance the quality of sound which comes from whatever brand of TV you currently have in your home, office, or other personal or private areas. To make this possible, your Sonos speaker must be connected to your TV to ensure that sound comes out without issue. What, then, do you do when the speaker continues to disconnect from the TV?

If your Sonos keeps disconnecting from the TV, be sure that you have your speaker properly set up first. To connect a Sonos speaker to your TV, you will simply attach a single optical cable or HDMI-ARC cord to the speaker and into your TV. Once this has been connected, you should be able to turn on the Sonos speaker and have instant sound, but to have constant sound, Autoplay should be enabled.

Autoplay is a feature that, when turned on, automatically selects your specific TV as the audio output. To turn on the autoplay feature, you will need to download the Sonos app to your smart device. Once you have the application opened, you will then go to ‘Settings’ > ‘Room Settings’ > Click on the room name in which you are in > go to ‘TV Autoplay’ > then choose to turn Autoplay ‘On’ which will enable a more seamless experience.

Sonos Won’t Play TV Sound

Sonos speakers allow for a rich and textured sound that is unmatched when it comes to most TV’s capabilities of sound output. The beauty of this system is that you are able to experience sound that can nearly rival any movie theatre while sitting in your favorite chair and never leaving the comfort of your own home. If you are able to play music from your phone, but find the TV sound is not working, you are left wondering where the gap lies.

If your Sonos won’t play the sound from your TV, one of the most likely causes is that the optical cable is not properly attached at one or both ends of the cable. To check to see how secure the cable is, plug it snugly into your Sonos speaker, but also be sure that it is securely inserted into your TV as well. If there is any budge on the cable, this can cause the transmissions to weaken which can interrupt the sound from your TV.

If the cables are secure and you are still not able to get any sound from your TV to your Sonos, check to see if the optical cable has gone bad. To do this, simply unplug the cable directly from the speaker and then look down the cable to see if a light appears within it. If there is a light, then there is no problem with the cable. However, if no light appears in the cable, then the cable is bad and a simple replacement will solve your problems.

Sonos Won’t Switch to TV

One of the greatest advantages to a Sonos speaker is its ability to switch from pulling audio from your smart device then can go right back to emitting the sound from your TV. This is wonderful for nights when dinner simply needs a robust soundtrack, but once dinner is over and you go to turn on your TV, you expect that the audio from your smart device to end and the audio from your TV to begin. What do you do if your Sonos won’t switch to the TV?

If your Sonos won’t switch to your TV, you can go into the Sonos app on your smart device and simply change what you have selected for the audio output. To do this, go into the application and simply select the TV that you want to play audio from. Once you have selected the TV, you should be able to play audio without issue, but be sure that the music you were previously playing is stopped.

If you do this and your Sonos still will not switch to your TV, completely exit out of the music application you are using on your smart device first. Once you have done this, you can turn off your TV then turn it back on, which should reset the TV and get audio back. Also be sure that the Autoplay feature has been turned on, which can be found under the previous section “Sonos Keeps Disconnecting From TV.”

Through the setup process, time is taken to ensure that every single feature of your Sonos is working properly and will be readily available come time for you to start playing audio from your TV. You may have gone through each step perfectly, but some owners have still experienced issues with their Sonos speaker simply refusing to connect to their TV. What then do you do if you can’t even get your device to properly connect to your television?

If your Sonos won’t connect to the TV, as previously mentioned, you need to first ensure that the optical cable or HDMI-ARC cable is securely connected to both your TV and your speaker. If you verify that the cable is secure at both ends, try removing the cable for 60-seconds and then plug it back into both ports. This may cause a reset which will help to absolve any minor connection issues.

If you are still having trouble with the speaker connecting, be sure that the red light on the inside of the cable is glowing, if it is not, then the problem is a bad cable. If this does not work, try unplugging your TV directly from its power source and allow it to perform a 60 second power reset. Once the TV has reset, plug the TV back into the power source and see if this helps to enable a connection between your Sonos and the TV.

For those of you that need a more specific solution tailored to the exact brand of TV that you are using, let’s talk about those of you with Samsung TVs. Just the same as any other TV, Samsung is able to utilize Sonos speakers so that you are able to have a clearer, richer sound that the TV itself simply cannot produce. If you have a Samsung TV but are unable to connect your Sonos speaker to it, read below for a few solutions.

If your Sonos won’t connect to your Samsung TV, it may be that your TV is in need of a software update. To complete a software update on a Samsung TV, from your remote press ‘Home’ > navigate to ‘Settings’ > ‘Support’ > ‘Software Update’ > ‘Update Now’ > then any new updates will be downloaded and installed. This will help to update your TV with a software that will accept your Sonos without issue.

If you perform the update and you are still having trouble connecting or if there is no new update available, be sure that there are no other devices that are interfering with the Sonos. To check this, unplug each device from your TV and then plug them back in one by one as you check to see if any of them, once plugged in, are what is causing your speaker to not connect. If one is the culprit, it will need to be uninstalled.
