Possibly a device to delay our D'TV video back into sync w/ the audio?

[mixsit]

We have an ongoing problem of our TV picture lagging the audio. It began with our switch from Consolidated to DirecTV, three or four months ago now. I think we got a quite good tech just out which gave us a good thorough second check.
As to our 'symptoms, audio leads video typically by half to three quarters of a second or more. (Two TVs both doing the same, all the time.) Reset their WIFI box clears it for 5 or 6 hours. He was aware of this, not sure how common though. I liked that he was interested enough to have me give him call for our status. ( 'fine first day or so.)

I want to say some of this has been curious as heck. If it is 'quite rare for example?
And/or 'solvable?
My search to D'TV.. came back with one 'thread, joined by two I think others, nearly a year and a half long(?) with no solution.
Looking around for it didn't do it. How or why (if it is so rare'?), I wouldn't even know how.
Fair enough.
So, I haven't yet, but close to looking for alternants..

But today, I guess some bit of my 'music/recording 'tech came in with delaying audio is plain easy, maybe video?
I got in a little ways. 24Frames per second ..perhaps(?) But half to a full second, didn't look so good at all.
What I found was '4.5 frames runs $650'ish.
Likely I may not know where to look? But everything I saw with high enough rates were way higher costs.
yikes.
Is the idea even hopeful?

Resetting the network connection fixes it for a few hours? What happens if you instead turn the TV off at the mains - is the problem still there when you turn it back on? Does the problem reset itself overnight?

What is doing the decoding? Is there a STB feeding the TV or is the TV doing the conversation from IP to pictures.

Sounds like a software problem that plays audio too slow, or video to fast… delay won’t solve this. Blame the new Box and have them fix it.

Streaming protocols normally fix this by aligning timestamps, otherwise different processing demands mean they start together and drift apart. Even so, I have seen some very long, uninterrupted streams loose gradual synch at the source!

So I think you are right, there's a bug somewhere in the decoder which is allowing different processing or clock behaviour to start drifting the signals apart. There are plenty of sensible ways to prevent this that have been deployed for years now. The supplier needs to fix it.

Thank you so much for these responses! I’ll use some short cuts here to help condense my answering.

-Yes generally.
What happens if you instead turn the TV off at the mains?
-I haven’t tried this.
Does the problem reset itself overnight?
-No. To add, other than they independently drop off line completely both TVs follow the same out of sync conditions.

-There is a single box that takes a light cable input. That broadcasts a Wi-Fi stream into the house. Each TV gets a little receiver ..‘thingy –tech term TVs are set to HDMI inputs.

-Insert 'Big Grin'.. Here’s the link to the forum’s thread I mentioned. I found it quite early on. (My 'take in all this hasn't changed much..)
What tech life I did have for one tells me- It doesn't fit with professional technical support- at all. First off it wouldn't simply drag on and on like that! Please for goodness sake.
So last, I’m here left with... Maybe they can’t fix it'.
And or worse maybe? They don’t care to?

Well, that’s a nice little shit show Trying to divert any relevant communication to DM… very transparent. Clearly their box is broken.

The thread does show one option you can try: set audio to PCM instead of bitstream (it may be called differently in your box, but it will have the same effect). See if that works..?

Definitely sounds like a bug in the sender or receiver's they don't seem to be sending proper clocks or synchronization, or the receiver is ignoring the (sync) clock.
