Hello , thanks for posting here with this concern. Please try the steps presented and let us know if this helps. 

Program Your Voice Remote To Control Your TV or Audio Device

• Press and hold the Microphone (Voice) button and say, "Program remote."
• You can also get there by going to the Settings page, selecting Remote Settings and then Voice remote pairing.
• Or you can use our online Remote Code Lookup tool or the Xfinity My Account app.

Program Your Remote Using Our Online Code Lookup Tool

1. Go to the Remote Code Lookup tool and pick the Voice Remote you have. Then click Continue and follow the steps in the tool to program your remote.
2. If you can't find the code in the lookup tool, check to see if your remote has a Setup button. Then follow these steps:
   
   

If it has a Setup button:

1. Turn on your TV.
2. Press and hold Setup until the light at the top of the remote changes from red to green.
3. Enter 9-9-1. The light should flash green twice.
4. Keep pressing CH ^ until the TV turns off.
5. Once the TV turns off, press Setup to lock in the code.
6. Press the TV power button on the remote. If the TV turns on, you're all set!
   
   

If it doesn't have a Setup button but has number buttons (XR15 Voice Remote for X1 or Flex):

1. Turn on your TV.
2. Press and hold the xfinity and Mute buttons together for five seconds until the light at the top changes from red to green.
3. Type the first five-digit code for the TV manufacturer.
   • If the remote light blinks green twice, the code is correct.
   • If the remote light blinks red then green, the code is incorrect.
4. Aim the remote at the TV, and press the Power button.
   • If the TV turns off, turn the TV back on and make sure the Volume and Mute buttons work.
   • If the TV doesn't turn off, try the next code.
     
     

If it doesn't have a Setup button and doesn't have number buttons (XR16 Voice Remote for Flex):

1. Make sure your TV and TV Box are on.
2. Activate the remote by removing the pull tab on the back.
3. Aim the remote at the TV Box and press the Microphone (Voice) button.
4. Follow the on-screen instructions that come up on your TV to finish setup.
5. If you’re already paired for voice, but need to program the remote to control your TV, just press and hold the Microphone (Voice) button and say, "Program remote." You can also go to the remote programming instructions via the Remote Settings menu.
   
   

If you’re still having issues (XR16 Voice Remote for Flex without number buttons), perform a factory reset:

1. Simultaneously press and hold the Info (i) button and the Home button (house icon) until the status light on the remote blinks. This takes about 5 seconds.
2. Press Power, then Last (<- arrow), then Volume Down (-) on your remote in sequence to complete a factory reset. Once this is complete, you can retry pairing your XR16 Flex remote.

Your remote lookup code does not work for me. I have a onn soundbar. That device name is not listed.

I am trying to control my soundbar with the xfinity remote. I can control the tv just fine. Not the soundbar.

OK, if the equipment is not listed then the soundbar may not be compatible. Do you have another sound device that you can test with? 

No I do not have one that I can use
