You should have a remote control to un-mute it.

A few things--first look to see if sound when using a DVD etc hooked to rear audio/video input.

Then look in set menu to make sure speakers did not get turned to OFF>.

I think you are muting the the remote before you relocated...you need a remote to un-mute the sound of your TV...this cannot be done using the volume control in your TV unless you have the remote...if you loss the remote...buy a universal remote control

Here's how to scan for TV codes on your DIRECTV remote

1.Make sure your TV is turned on.

2.Slide the mode switch at top of remote to "TV".

3.Press and hold the MUTE button. This is located above the number 1 button.

4.While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

5.Then enter 991, the green light on remote should flash twice.

5b. Press 1 again (it will flash twice again), then you press the power on button at the very top right.

6.Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

*If you hit channel up very fast, you risk going past the code. Pressing channel down will back it up. I alway hit channel up very fast till the tv turns off, then back it up slowly till it comes back on.

7.When the TV powers off, press and release the SELECT button.

*Note: If the green light flashes three times before TV responds, then all codes have been cycled through. Our remote controls are guaranteed to program to your DIRECTV receiver, however your TV may not be compatible with our remote control.

The audio is not working. Tried to mute and un-mute and that's not the issue.

Do you have a little symbol on the screen showing a speaker crossed out? If so you have pressed the 'mute' button. another press of the same button should un-mute it.
