AT&T auto audio volume lowering

What setting do you have on the receiver/dvr?  I recommend you always keep that set to 25, i.e., as high as it goes.  Refer to your uverse remote user guide on how to set the dvr/receiver volume.  Once that is set you should never have to set it again (unless you get a new dvr/reciever of course).  From this point on you control the volume with the tv's volume control, and if your remote is programmed correctly for your tv model, you should be able to control it from the uverse remote.

While not all stations may have the same volume for the same setting, for any one channel, the volume doesn't using vary (unless something weird is going on with that particular station).  If it is noticeably changing then maybe your tv has some kind of audio compensating setting (can't imagine what) that's lowering the volume because the dvr/receiver certainly isn't doing it.  See what your tv's user manual has to say about volume.

Some random other thoughts, experiments, and questions (in no particular order):

• Are you using a sound system or the tv's speakers?  If sound system how is the tv's audio only?
• Play with the dvr/receiver sound options; on uverse remote press menu->options->audio/language->digital audio output and try stereo and surround sound.
• Try a different hdmi input port on your tv.  Try component cables instead of hdmi.

Is DVR volume still even a thing? I remember being able to do it on my old 1225 silver DVR. I've since switched to a black DVR and the remote doesn't have the various mode buttons...just one for power.

I have reset the low volume via trouble shooting. It shows 25, but if I run it again is still states low volume. I am using the TV speakers. I have
done the trouble shooting about 4 or 5 times over the past 6 months. Like I said, I use to get by at 10 last week now it is 25 or 30 on the TV.

Just to be clear here is the "25" your tv's volume level which means nothing to me since you never made it clear what your tv scale is up to max.  Or is that 25 show in the upper right with a circle around it?  That one is from the dvr/reciver (whichever the tv is attached to).

 I have tried stand and wall settings on speakers with no change. I have changed the settings from Dolby to surround, no difference.

I am not  not interested it what external audio systems you tried (at the moment at least), only the tv's audio for the tv connected to its dvr/receiver.  Who knows about your external stuff?  For all I know it could some weird impedance mismatch that could screw that stuff up.  Don't need extra variables in the mix when trying to troubleshoot.

Why is AT&T trying to control how I watch my TV?

They are not trying to control anything with your audio.  I believe it's something wrong on your end.  While I can't eliminate a defective dvr/receiver did you at least look at the bullet items at the end of my post 2?

Ok... I've confirmed that the DVR is up to 25 volume.

And I just figured out that the blue "Interactive" button makes my TV's volume bar and mute notifications disappear from my TV...it was quite annoying to have those pop up.

Yes, a very big thank you for the fix . I also HAD a volume issue with my  tv using the new s-30 remote. I read many other posts

and am thankful i came across yours and my volume issue is now solve. I now have a very happy wife....thanks again and best regards,

Pete
