To help you understand this problem better, let’s review the causes of these issues!

Why Is My Xfinity X1 Sound Not Working?

Xfinity X1 is only available to customers who have subscribed to the Xfinity TV or internet service, thus making it accessible to only a selection of users.

Though it’s affordable, Xfinity X1 still has plenty of online streaming services available, such as Peacock, HBO, Amazon, Hulu, and many more.

However, many users have reported that particular Sound Issues have occurred with the platform, that disrupt streaming and could be really bothersome.

Here’s why they occur:

• An issue with the Output Sound Device
• Inappropriate Xfinity X1 Settings
• Problems with the Firmware of your Xfinity Box
• Improper Audio Settings

All those things could have an impact on the sound output of your Xfinity X1 service.

Thus, these are quite easy to take care of, but we still have to go through some basic troubleshooting!

Xfinity X1 Sound Issues – Fixed In Minutes!

In the upcoming guide, we’ll be going through all of the best resolutions you could think of when it comes down to sound issues with your Xfinity X1.

As long as your Xfinity TV and Internet subscription plan is paid, you have nothing to worry about!

Let’s jump into the guide!

Solution #1 Reboot your TV Box

As simple as it sounds, the first thing you should do is perform a Reboot on your X1 TV box.

A basic refresh of the system might help things get going and resolve the audio problems you’re constantly experiencing with your box and the X1 service.

It is possible for a temporal fault that has developed, to have an impact on the audio stream of the Xfinity box to the TV.

Here’s how to reboot your TV box in easy steps:

1. Unplug the TV box from the power source, by shutting it down beforehand.
2. Wait for multiple minutes, while the TV box is discharging.
3. Reattach the power cable of the box back into the power source.
4. Test the audio…

On a high note, the TV in your setup is the one that should be outputting the sound.

The Xfinity X1 cable box will transfer both audio and video through the HDMI connection and your TV’s in-built speakers will be used to output the sound of whatever you’re streaming on the box.

Tip: When disconnecting your box, you should also do the same for your TV.

Solution #2 Unmute the TV/Increase the Volume

In this step, we’ll be taking a look at your TV’s basic settings, more particularly, making sure that the device isn’t muted or its volume hasn’t been lowered.

In your setup, you should be in possession of two remotes, one for the TV and one for the Xfinity X1 box.

We’ll be using the TV remote, to make sure that your TV hasn’t been muted. This is an often occurrence, where the users use their TV for something else and accidentally mute the device.

• On the remote, press the “Mute” and the “Volume +” buttons multiple times!

The moment you press the mute button, a “Mute Status” will appear on the display of the TV. If the volume icon that appears has a cross on it, it means that you’ve just muted your TV.

If the volume icon appears in white color, without a cross, it means that you’ve unmuted your TV.

Note: Using your TV will only interact with the TV itself and not the cable box!

Solution #3 Change the Audio Mode

In this solution, rather than the previous solution, we’ll be browsing the Audio Settings of the X1 box.

Yes, your X1 box has sound customization settings that could alter how the TV outputs the sound of streams and broadcasts you’re playing.

Taking a deeper look, we’ll be adjusting the audio mode of your X1 box, which could be making interference with the sound output.

Here’s how to alter the audio mode of your X1 box:

1. On your TV Box remote, press the Xfinity Button.
2. Head to the Settings.
3. Highlight and choose “Device Settings”.
4. Use the down arrow to select Audio.
5. Choose “HDMI Audio Output”.
6. On the next page, highlight the “Auto Detect” feature.
7. Save the changes and exit the menu.

We’ll not be making any particular changes to the audio mode of your Xfinity Box, but placing it on “Auto Detect”.

This will allow the system to look for the most comfortable audio mode and automatically adjust according to the highest quality of sound output your setup could reach.

Note: Make sure that the TV is connected to the box securely, before switching the audio modes.

Solution #4 Disconnect Third-Party Speakers

If you’re using a third-party speaker device, this could be where the problem is coming from.

In this solution, we’ll want you to expose the volume of your TV to its basic value and make sure there is no third-party impact on the functionality.

In order to achieve that, you’ll have to get rid of any connected speaker devices to your TV or cable box and test.

• Unplug the AUX cables of speaker devices associated with your setup and test!

However, assuming your TV has already made the change in audio settings, you’ll have to select the TV speakers as the default output device from now on.

On most TV interfaces, go to Settings > Audio > Sound > Default Output Device > “TV Speakers”.

Alert: Plugging audio devices will cause this setting of your TV to automatically shift.

Solution #5 Switch Audio Device Input

If using a third-party device along with your X1 box, we suggest switching the audio device input on your TV.

Chances are that you’ve connected an audio system to a non-working port and the TV has already shifted its audio settings to acclimate the new device, but it isn’t responding.

• Plug the audio device into a different audio port on your TV or the X1 box!

The majority of X1 TV boxes have an audio jack, to avoid messing with the TV’s configuration.

However, keep in mind that using the box as the sound center, requires disabling the sound of the TV, so the audio streams don’t overlap.

Our best suggestion is to use the TV as the audio center and connect the speakers there!

Note: If you didn’t mute your TV when your box is in the audio center, you’ll hear the broadcast twice.

Solution #6 Refresh the Xfinity TV Box

If none of our solutions worked so far, then you should perform a Factory “Refresh” on the Xfinity box.

Since Xfinity X1 and Flex streaming boxes also work as a router/gateway, you’ll have to use a networking button in order to trigger the desired refresh.

Alert: If you’ve also benefited from the Xfinity internet service, refreshing the box will temporarily bring your network and WiFi threads down.

Here’s how to refresh your Xfinity box in easy steps:

1. Turn off the box by pressing the Power Button once.
2. Wait for the device to shut down.
3. Press the power button along with the WPS button.
4. Hold both buttons for an average of 10-15 seconds.
5. Wait for the LED light on the box to turn an amber color.
6. The Disaster Recovery image will appear on your TV’ screen.
7. The box will not begin updating its firmware.

Once the refresh has been completed, test if the audio now works on your X1.

Note: Be patient while the reset is still undergoing and do not interact with the box in any way.

Quick Recap:

Thus, to resolve Xfinity X1 sound issues, you’ll have to reboot the TV box, then unmute the device and increase the volume.

After that, alter the audio mode, temporarily disconnect third-party speakers, and refresh the TV box to factory defaults.

Do not hesitate to contact Xfinity Support if you’re still having issues with X1!
