The Xfinity remote, especially the modern voice-controlled models, is designed to be the single controller for your entire entertainment system. If you have a Vizio soundbar, programming your Xfinity remote to control its power and volume is the final step to a truly streamlined setup. This guide provides the specific codes and expert tips to ensure it works perfectly.
Before You Start: Understanding Line of Sight: A common point of confusion is that your Xfinity remote can change TV channels without being pointed directly at the cable box (this is called RF or “aim-free” technology). However, for controlling your Vizio soundbar, the remote uses traditional infrared (IR) signals.
This means you MUST have a clear, direct line of sight between the remote and the front of your Vizio soundbar for the volume commands to work.
Step 1: Find the Best Code for Your Vizio Soundbar
There are several codes that work, but one is generally more reliable than the others. Start with the first code on this list.
- Most Common Code: 32454
- Alternate Codes: 31517, 30660, 31948, 11756
Step 2: Program the Code into the Xfinity Remote
This process syncs the remote to your soundbar.
- Make sure your Vizio soundbar is turned on.
- Press and hold the SETUP button on your Xfinity remote until the top LED light turns from red to green.
- Enter 3-2-4-5-4 (or your next choice) using the number pad.
- The green light on the remote should flash twice. This confirms the code has been accepted.
- Aim the remote at the soundbar and test the Volume and Mute buttons.
If the soundbar responds, your setup is complete. But what if it’s still controlling your TV volume instead? This is a common issue with an easy fix.
Troubleshooting: How to “Lock” Volume to Your Soundbar
By default, your Xfinity remote might be “locked” to controlling your TV’s volume. You need to tell it to send all volume commands to your soundbar instead.
- Press and hold the SETUP button until the LED turns green.
- Enter the code 9-9-3. The LED will flash green twice.
- Now, press the AUX button once. The LED will flash green twice again.
This procedure “locks” the volume control to the AUX device you just programmed (your soundbar). The volume buttons will now control the soundbar, regardless of which mode the remote is in.
If you’ve tried all the codes and it still isn’t working, the soundbar itself may have a glitch. A full factory reset often solves these deeper issues, a process we detail in our guide to fixing an unresponsive Vizio Soundbar remote. It’s also essential to have already successfully paired your remote to your Vizio TV before starting this process.
Conclusion
Programming your Xfinity remote for a Vizio soundbar is more than just entering a code—it’s about ensuring the volume commands are sent to the correct device. By using the primary code and applying the “9-9-3” volume lock trick, you can achieve seamless control over your entire Vizio home theater setup, solidifying your Xfinity remote as the only one you’ll need.
