3. Verify Your Connections

Inspect all the cables connected to your Xfinity cable box and your TV.

Make sure that the HDMI or coaxial cables are securely connected and that there are no loose or damaged wires. A loose connection can often cause sound issues.

Additionally, it’s important to check for any signs of wear and tear on the cables themselves, as damaged cables can lead to audio loss and should be replaced if necessary.

4. check the HDMI Audio Output

If you’re using an HDMI connection, the issue might stem from the HDMI audio output settings.

Navigate to the sound settings on your TV and ensure that the HDMI audio output is selected and not another source like internal speakers or a digital optical output.

This ensures that the audio signal is being sent through the HDMI cable to your TV from the Xfinity cable box.

steps to ensure HDMI audio output is selected:

  • Access the TV’s sound settings using the TV remote.
  • Navigate to the audio output options.
  • Select HDMI audio output as the default.
  • Confirm the change and exit the settings menu.
  • Check if the sound is now working through the HDMI-connected device.

5. make sure the audio setting on stereo or PCM

In your audio settings, verify that the output is set to either stereo or PCM (Pulse Code Modulation).

Surround sound formats like Dolby Digital can cause compatibility issues if your sound system doesn’t support them.

Setting the audio to stereo or PCM can resolve these issues by providing a format that is widely supported by most TVs and sound systems.

steps to set the audio output to stereo or PCM:

  • Go to your device’s settings.
  • Look for the audio options.
  • Go into HDMI audio output.
  • Select Stereo or PCM as the output format.
  • Save the changes and exit the settings.

5. Factory Reset The Cable Box

If all else fails, a factory reset of the cable box can be a last-resort solution.

This will restore the device to its original settings, potentially resolving any sound issues caused by incorrect configurations.

Keep in mind that a factory reset will erase all personalized settings, so you will need to set up your preferences again after the reset.
