If you ever find your Xfinity Flex sound not working, you’re not alone.
In fact, hundreds, even thousands of people are trying to look for a solution to this problem, and you’re lucky because, in this guide, that’s what we will tackle!
Other than giving you the reasons why the audio of your Xfinity Flex is not working properly, we will also give you the complete and comprehensive solution to fixing and resolving it!
If the sound of your Xfinity Flex is not working properly, try checking if the device is muted, and check if you are in the correct TV audio output. Then, perform a reset of the streaming device.
Before we get to the solution to this dilemma, it is relevant to understand the causes of why this is happening.
As easy as we want it to be, this is not a one-type problem with a single solution.
Whether or not you’re experiencing this problem with one (1) or more televisions, the common causes include:
- There are devices (headphones, earphones, etc.) plugged into the TV
- The device has accidentally been muted
- Your box or adapter isn’t directly connected to the television
- You’re under the incorrect audio output
The cause could be one or any of these, and it will be difficult to figure out one by one. So, what can you do to appropriately resolve the problem of your Xfinity flex audio not working?
This is a comprehensive guide that will help you in fixing the no sound problem you’re experiencing with your Xfinity Flex device.
If your problem only happens with some channels, then, this will be what you need to follow.
Yes, the solution is different if you’re only experiencing it on a few select channels. So, here’s the process that you have to follow!
Step #1. Locate your device’s Multichannel Television Sound (MTS) setting.
- Change SAP or MTS to Normal or Off.
- Change Stereo or Stereo/SAP to Normal or Stereo.
Step #2. Verify the Default Audio Track on the device.
Step #3. For TV Boxes, access Main Menu > Setup > Audio Setup.
Step #4. For TV Adapters, press INFO on the remote > Setup > Audio Setup.
Accessing the MTS or SAP settings would differ from one device to another.
If you are using a new remote, you can access it by pressing the SAP or MTS button on the remote.
Should you be using a TV adapter, you’d have to press the LANG button, but, if your remote is an XR2 remote, you’d have to press Xfinity > Audio Preferences > OK, and then change the language.
Should the problem be affecting all channels on your Xfinity Flex, this is the step-by-step guide that you need to follow.
There have been many occasions where people accidentally put their devices on mute.
So, the first step is to check if you have disabled the sound of your television or any other device that’s being used (e.g., a speaker, subwoofer, etc.).
Ensure that all devices have sound.
After that, double-check if you’re using the correct device for the audio output.
What this means is that there could be an external device, like headphones, earphones, or any other type of audio device connected to the television.
After that, you have to ensure that the box or adapter (Xfinity Flex) is connected directly to the television.
If there are other devices connected and if you’re managing the volume using these devices, ensure that the TV box or TV adapter is not muted.
Then, the next step is to check and verify the TV audio output you are using. You can check this by accessing Settings on your television and going into Audio > Audio Output.
Make sure that it’s set to the correct audio output. By now, this should be enough in solving this particular dilemma.
And to finalize the process, the last step is to reset your Xfinity Flex. Factory resetting your Xfinity Flex is easy, in fact, you can do it in a couple of steps:
- Power on and activate the device.
- Hit on POWER + MENU on your remote simultaneously.
- Then, press the UP + DOWN arrows on the remote.
- Choose the option that says Restore Defaults.
- Lastly, press OK.
Wait for the system to reboot and reinitialize. Once it’s done, the settings will be changed to factory default settings.
After you perform these steps, you’ll then be able to fix up and resolve the problem of your Xfinity Flex’s audio not working!
If you’ve done the process and the issue remains unsolved, what you have to do next is to contact Xfinity’s customer support team.

This way, they’ll know the troubleshooting steps that you’ve accomplished in an attempt to solve them!
If you’re not having any sound coming out from your Xfinity Flex device, ensure that there are no external devices plugged in, check if the device is connected directly to the TV, then verify the audio output. It’ll also be helpful to reset the device and start anew.
