Resolving U-Verse and Vizio Smart TV Sound Issues

U-Verse and Visio Smart TV Sound Issues

I recently ran across an interesting issue with an AT&T U-Verse receiver model 1SB7005, and a Vizio Smart TV model M492i-B2. My customer complained that the volume would lower itself and after a few moments, would go back to where it was initially set. The TV would do this all by itself, without any input from my customer. Weird! My customer was running the sound through his TV, not his Sony Audio Receiver model STR-K5800P (We took care of running the sound through his audio receiver after we fixed his sound drop-out issue). The solution to the problem is a two part fix, see below.

Without any human intervention, the TV volume would lower itself and after a few moments, would go back to where it was initially set. The solution to the problem is a two part fix.

The Vizio Fix

It turns out that the SRS TruVolume feature of the Vizio smart TV was trying to balance the sound output from his TV. You know how sometimes the commercials blare at a very loud volume level compared to the show you are watching? The SRS TruVolume is supposed to alleviate that annoyance. Unfortunately, this feature was in conflict with the audio signal from the U-Verse box. I turned this feature off by following the sequence outlined below.

  1. Press the ‘Menu’ button on the Vizio remote to get to the TV’s main menu.
  2. Select Audio settings.
  3. Select Advanced Audio.
  4. Toggle the SRS TruVolume to off.

This sequence fixed the volume randomly dropping out, but now the sound level was so low that I had to turn the volume on the TV to 90-95 in order to listen at a near-normal level. The volume was not any better running through the Sony Receiver, though the receiver had more head room which allowed for a slightly higher volume than the TV.

The U-Verse Fix

The second part of the fix involved getting the U-Verse box to deliver the audio signal at a higher base level. This was accomplished by hacking the U-Verse remote and turning the audio signal up. I did this with the following steps.

  1. Turn the volume on your TV down to about 25 or so.
  2. On the U-Verse remote control, press both the AT&T button and the OK buttons simultaneously. Release both buttons at the same time. The mode keys should flash twice indicating the remote is now in programming mode.
  3. Using the number keys on the remote, press 9 - 5 - 5. The mode keys should flash twice indicating a correct entry.
  4. Press the AT&T button at the top of the remote. The AT&T button on the remote should flash three times, letting you know that you are now controlling only the U-Verse receiver.
  5. Press the volume up button.

A speaker with curved lines, which is different than the normal volume level scale, should appear on the screen. This tells you that you are now increasing the audio signal level of the U-Verse box. If you see the normal TV volume scale going up, go back to the second step above and go through the steps again. Max the U-Verse signal out at level 25. Now return the remote to its normal operation with the following steps.

  1. On the U-Verse remote control, press both the AT&T button and the OK buttons simultaneously. Release both buttons at the same time. The mode keys should flash twice indicating the remote is now in programming mode.
  2. Using the number keys on the remote, press 9 - 5 - 5. The mode keys should flash twice indicating a correct entry.
  3. Press the TV button at the top of the remote. The TV button should flash three times, indicating the U-verse remote will now control the TV volume again.

You should now have normal volume levels available through your TV speakers.

Conclusion

The above steps solved the volume issues for my customer. He now enjoys normal volume levels watching his Vizio Smart TV. Now what to do about that Sony receiver? That will be addressed in a different article. Stay tuned!

    yes! This has been driving me nuts since adding u- verse to my TV. Thanks for sharing this info. One note of correction however, in my case I had to press the AT&T button first and then the ok button, holding both at the same time. Pressing and holding both at the start would not work for me.
    Thanks again! I almost retuned my tv and or u-verse thinking it was something wrong.

    I am using an external speaker connected to the uverse box, but had no way to control the volume. If I complete steps 1-5, and leave it in this state, will that leave the volume controls for the uverse box? I only want the tv control for power and leave the volume all the way down. Unfortunately, there is no way to disable audio in the model of tv I have.

      If you leave the U-verse remote in the U-verse only mode, it will only control the U-verse box, and not anything else – like your TV. This means that it won’t turn the TV on or off either. You question implies that you have a direct connection (digital, audio cable?) from your U-verse box to an external speaker (sound bar?). If this is accurate, a better solution would be to program your U-verse remote to control the volume of the sound bar instead of the TV volume. See our article that shows you how to accomplish this at the following address: http://www.nextstepaudioenhancement.com/how-to-program-your-cable-or-satellite-remote/.
      This way you can manually turn the TV volume down and only use the sound bar when using the remote control. The best answer would be to upgrade to a universal remote control like the Logitech Harmony that you can program to seamlessly control everything.

      You can get replacement remotes from your AT&T provider. They will charge you for it though. Make sure to give them the model # from your AT&T box to make sure you get the correct remote.

    I am having the same issue, but the tech could not fix it. The new remotes from u-Verse do not have at ATT button anymore. Can you give instructions on how to fix the volume issue with the new remotes?

    You can still go through the first part of this fix to get the TV itself to stop adjusting the volume. To do the second step, you will need to contact your local AT&T and ask them how to put their remote into AT&T only mode. Once you have re-adjusted the AT&T volume output, you will have to reverse the instructions to put the remote back into ‘universal’ mode. Make sense?

    Vizio TV folks: my path for my smaller smart TV was Menu-> Audio-> Sound Leveling -> Off. Whew.

    Thank you, Brian! This was driving us crazy! We, too, had the new remote with no AT&T button, but also had an old remote for another box in another room. We used it for the “Uverse” portion of the fix, then switched back to the new remote. Works like a charm!!
