No sound from one specific TV/Uverse receiver

If you have more than one U-verse TV Receiver, swap one of the others to this location and see if the Digital sound works using that receiver.  If not, check the cable/fiber..  If so, then contact AT&T for a replacement receiver.

@geebz25 - Your Language setting may have beeen changed - ENTER(bottom right) - Audio language should be on english.

Since Tv does not have surround decoder - make sure on stereo MENU- audio lang opts- Digital audio out.

We have not seen phantom MUTE in a long time - could be the STB is muted - usually can be restored by by pull the plug reboot

Program remote - att/ok-955-enter 

In att mode press vol up to get to 25 on screen

reprogram att/ok-955-TV-ENTER

@geebz25 im not sure if this option is still there (Its been a while since ive done CSR work)

This is under Menu > Help > Troubleshoot & Resolve

There should be a no sound option and it will run through a diagnostic for the receiver, it could be that the receiver itself was placed under mute or the volume turned completely down.

This can happen if a uverse remote was used from another TV and wasnt programmed to the current TV and was placed on mute or turned volume down.

When a remote is programmed to a TV, using the Mute and volume options it will change the TV setting and not the recevier, when using a remote not programmed to a TV it will use the receivers volume and the mute options.

Thanks everyone. I will try these when I get home. There is a very good chance a different remote was used by my family during Thanksgiving.
