STB loses audio when UN-pausing live TV

Weird, weird problem:  One ONE of my new wireless boxes after I pause a LIVE program (say...for a phone call) when I UN-pause it, there is NO audio...nothing, nada, silence.  I tried channel up/down and it's even muted on other channels.  And it doesn't happen all the time...maybe 1:5 times.


No amount of adjusting the volume will work.  It's like it's on mute.  The only way to get sound again is to turn the box off and back on again.


Thank goodness this is on the least used TV so it's not that big of a deal but it IS an annoyance and it disrupts my ability to pause a program.

Re: STB loses audio when UN-pausing live TV

skeeterintexas - IR corruption is certainly a possibility. I experience corruption of FF or play into chan up/down.
Do you have a remote that you can program to control the STB sound? The next time it happens use the remote to send avolume up or mute. If it un-mutes, it is IR corruption.


While I was typing this post I was looking at my STB. I have the blue light covered with a kind of duct tape that I got in home depot in the electrical section. It is designed for easy removal - to be used for temporary fastening. Its surface has little ridges. I was surprized to find it has a degree of transparency when I put it over the lights.


I started thinking that it would be a great filter for the IR. I just tried it over the IR sensor & it worked great on all button presses. Musc more reliabe - no searching for the sweert spot. FF through the ads in an hour show, without once changing to a chan up/down.

Re: STB loses audio when UN-pausing live TV

I have experienced the same phenomenon.  I didn't really understand the reply you received to correct this situation. If you have resolved the issue, can you please let me know what to do on my end?

Can you explain your response and assume that I don't know what STB or IR mean.  Also, could you include more details, please?

Re: STB loses audio when UN-pausing live TV

cjuenke - IR is infrared - shorthand for the invisible light that the remote generates to control the Set Top Box (STB). There have been more problems posted with the U-verse remote than any other remote I have seen.

Previously, there was a spate of some button registering as an STB mute. This is especially bothersome because of the way the remote is programmed - When the TV is programmed the volume/mute buttons control the TV. To change it you need to - att/ok - 955 - att - enter. Then the volume mute buttons control the STB. YOu can leave it this way by setting the TV volume to a comfortable level when the STB is set to 15. Then you can raise or lower the volume as necessary.

So, set up your remote as above & the next time you lose volume press mute or volume up & see if the volume returns. If it does you can try this solution - cover the IR sensor on the STB with this tape that you can get at the Home Depot. I used to get about six IR corruptions a night. Since I put the tape on - over two months ago - I have not had one (or more than one).

Here is more on subject including the name of the tape -

IR Issues

Going back 5-6 years there are many posts about IR interference. Remedies included taping over the IR sensor, hiding the STB, turning off auto brightness on the TV.

A common fault was the info button press corrupting to an STB mute action. The number of reports of this have totally fallen away. My personal initial primary problem was getting the zero to register. But, one day long ago that just went away.

Niles Audio Corp. makes IR repeaters & has a video on their web site showing the fragility of the IR coding that is used for U-verse & other boxes. They said their new line of repeaters could handle it. Oddly, a U-verse customer posted in this community that they had a NIles install that was not working & after they contacted Niles they did not get any satisfactory resolution.

I came to believe that the IR sensor is too sensitive, That the DVR is worse than other STBs. That command type buttons are worse than the number buttons. That, somehow software updates can make it better or worse, So, it is a moving target. Hard to pin down.

I noticed that the U-verse remote does work better than my Logitech Harmony model 700. I looked at the IR signal through a digital camera. It appeared to me that the Harmony IR signal is stronger than the U-verse remote. This reinforces my theory that the IR sensor is too sensitive.

Recently, my most common problem was FF and Play Buttons often corrupted to chan up and chan down more than six times a night while watching recorded shows, exclusively.

I happened to notice that I had a specific kind of "duct tape" covering the blue light on the STB. Actually, it just looks like duct tape, but is electrical tape available at the Home Depot in the electrical dept. -

This tape has a degree of transparency. I thought I would use it to cover the IR sensor. The remote has never worked better. In over 20 evenings since I applied the tape - watching recordings while FF through the ads - I have not had one chan up - chan down corruption . Previously, there would have been at least 6x20=120 occurrences.

Almost all button presses are accepted & none are changed to a different action.

RF Issues

It should not be a surprise, but it is, that half the problems with the RF remote are IR. I run an STB well hidden for a second TV. I had the IR sensor covered with black tape. I replaced the black tape with the "duct tape" & saw an immediate improvement in response to menu buttons. The number buttons were already good - see below for that solution.

The STB using RF must be hidden due to the dongle conversion of RF to IR. If it is not hidden it is subject to the following problems:

IR corruption - Ironically, the RF remote was often offered as a resolution for IR problems. But, if the STB is not hidden nothing has changed to eliminate theI IR corruption problem. If the corrupting light can be seen by the STB IR sensor it will continue to corrupt the IR signal.

If the STB IR sensor can see IR from another remote, it will respond to it.

If another STB can see the IR generated by the dongle, it will respond to it.

Note that hidden means the IR does not see outside light - If you have an optical repeater it is IR subject to corruption. If you have an IR receiver that produces RF to go through a wall, it is still IR subject to corruption. Only if the remote is RF (like the point anywhere remote) transmitted to a hidden device will it ward off IR corruption.

Previously, I found the RF remote lacking in RF power - in the same room, twelve feet away, hidden only by a thin sheet of cardboard. One method to increase RF power is to hold the remote under your chin while pressing a button - using your head as an antenna.

A better way is this antenna placed in the battery compartment -

With this antenna, the channel numbers are almost always accepted. With the "duct tape" in place, the other buttons work almost every time. The remote now works better than ever.

STB Issues

Once IR and RF issues are resolved, there are timing issues with the STB to contend with. Numbers process fast and Menu items process slow. You need quick, light touch on some numbers to avoid duplicates and a slow, strong press on menu activities. Effort is required to suppress the urge to press again while waiting for a response. It takes concentration to get effective results. Frequently a second press immediately cancels a slow responding first press. Current IR and RF issues amplify the effect of the timing issue.

Skeeter have you tried doing a hard reset to that STB?  I suggest doing a hard reset to the RG and the the STBs.  It could be corruption in the software, and this wll cause the software to be redownloaded into those devices.
