Picture lags behind sound, and I can't seem to compensate
Has anyone managed to see an improvement in picture to sound sync, when adjusting in the settings? My picture lags well behind the sound. Always has done, I think. Difficult to say how much, but I'm guessing 100 to 300ms range. Adjusting the setting doesn't seem to help. And the menu don't explain whether it's delaying the sound or delaying the picture, so it could even be making it worse. Thanks
While not recording, nor about to, touch the On/Standby button on the box for just over 8 seconds until it soft reboots.
This won’t lose any of your settings, or recordings or anything; it will just make sure the box refreshes its running software from its own internal copy.
Visionman, I'm using HDMI (AV5) to the T2100, and another HDMI (AV4) to a Sony BlueRay (which rarely gets powered up). No SCART.
If one or both of those are out of sync, it points to a problem with the TV; if not, it throws the focus back on the YouView box.
Almost definitely, as broadcast sound and vision aren't encoded separately, they come together.
Which is why @Visionman’s comment that the sound and vision arrive together down your aerial does not imply that they will leave together from your screen and your speakers.
Let alone that having arrived together down your aerial to the YouView box and been passed by HDMI to the TV, and then displayed by the TV, it is possible to eliminate the YouView box as the source of the trouble.
A proper investigation of this issue requires that the following configurations are tested, until the problem is isolated, and @Niggle needs to carry out those that he can and report back:-
Aerial direct into TV.
Alternative device (e.g. his BluRay player) to feed TV via HDMI, over the same HDMI cable into the same input the YouView box uses.
YouView box feeding an alternative TV.
That last test could be the most definitive, but perhaps not the easiest to carry out, depending.
My feeling is that it's only YouView live TV (and maybe only some HD channels) that exhibits the problem, not recorded programs, and not BlueRay. Which obviously points to YouView, not the TV. YouView to an alternative TV would be definitive, but I don't have one.
I think my next step will be to start an instant recording on a channel when the sync is bad, and see if that recording is also bad ...
So I think this shows it's not the TV, but something peculiar to particular channels, either with the decoding in the T2100, or with the incoming signal. I'm pointed at Hannington, in case that's significant.
Maybe the problem has always been with just channel 109. Weird?
I always think that as long as you can straightforwardly connect to YouView, it is better to have a new, known good, copy, rather than the backup copy already on your box. Which might be just as good, of course. Or might not
A bit mystified by that comment, to be honest. Are you referring to this specific issue?
YouView mark Option 2 as Recommended, and suggest, if that doesn’t work, Option 3, which deletes your recordings.
My understanding is that Option 4 is like Option 2, but the software is refetched from YouView’s servers, rather than from a copy held on the (now suspect) box.
Maybe this is not the case, but YouView have never explained why or where my reasoning might be faulty.
And the Factory Reset in the Settings Menu has been described as equivalent to Option 5, not to the (recommended) Option 3.
So it’s a nice judgement - with a sick box, would you rather have the certainty that nothing can go wrong refreshing the software, but the worry that you might be doing it from a faulty copy (Option 2), or the certainty that you are accessing a good copy on YouView’s servers, but the worry that something might go wrong in the transfer (Option 4)?
Obviously, if you have a problem with connecting to YouView, you have no choice but Option 2; but when the connection is OK, I prefer, and recommend, Option 4.
Assuming that YouView’s recommendation doesn’t just reflect a desire not to have their servers overloaded (or even if it is indeed just that!), I would welcome a statement from YouView on the rationale behind preferring Option 2 to Option 4.
If yes, I think I'll just try to avoid channel 109 for now. The benefit doesn't justify the risk.
But your schedule is now held in the cloud for you, and crawls back onto the box over the next hour or so.
