Did some analysis, according to ffprobe, there is frame data missing in the ts file, so it is corrupt.
Now the question is whether that is a recording issue, or a broadcast issue, since it happened on two occasions, same channel ( RTL 8 HD, on 23.5) , and I record lots of programmes a day (I hardly ever watch something live).

At the moment, AC3 suddenly dropped on NPO1 HD, 23.5. while I was watching.
Confirmed by others, using varied equipment, so I think it is safe to say this is a provider related issue, and switching to another OpenPLi release is unrelated (just tried 8.3, 9.0, develop, scarthgap and OpenVIX 6.6, all having exactly the same issue).
The MPEG audio stream is not affected, and works fine.

Which is weird, because NPO1 and RTL8 have different sources? Or are they uplinked from the same location?

Hello.
And it's here again :). Falling sound, for Vu+ devices.
On the one hand, I have to say that in the case of my Zero 4K there is no problem even after the Enigma2 update.
On the other hand, I have to say that in the case of my Vu+ SOLO SE V2, the problem happened again (yesterday). I have already described it here:
1.) set top-box works normally for several hours or days
2.) then there is a situation where the sound is sometimes lost for about 3-5 seconds, but it reappears and continues to work... this repeats about 2x-3x, over a period of about 1 hour
3.) finally the sound stays off permanently (video works fine)
4.) if I try:
4.a) switch Enigma to standby mode and immediately wake it up again...
4.b) disconnect and connect the HDMI cable (on the side of the set top box) while both the set top box and the TV are running
4.c) switch the TV to standby + then wake it up from standby
...so in all these cases the sound works fine again... the sound also turns off after about 3-5 seconds... and then the sound remains off
5. only turning off + turning on the set-top box will help (mains switch on the back panel of the set-top box)
I don't know if the drivers have changed. But something else might have changed in the Enigmas that has compatibility issues with these original Vu+ hardware drivers.
Also...unfortunately...I haven't noticed yet if this problem only affects AC3 or other audio formats as well.
My preliminary guesses are that it could be issues with the HDMI cable or the HDMI interface on the Vu+ device. The video works, but the sound does not. But that's just my dumb guess. It doesn't have to be like that at all.

I already gave my two cents about cables
you cannot disconnect HDMI cables whilst those apparatus your using are powered on. It can lead to loss of audio and or video but can also destroy the HDMI board.
I myself have not seen such faults regarding the sound.
It would require some further information from YOU about the image version and the broadcasting channels you are watching when such audio faults occur.
The assumption that it might be a driver issue is rediculous because them drivers havent been changed since the development stopped for OLD models of Vu+.

Yes, I know that HDMI could damage something, but it is an EXTERNAL PERIPHERAL INTERFACE and therefore it is allowed to connect cables while running / using devices. For example, when the TV is already on, you can safely connect cables to HDMI. What you write probably only applies in specific cases... but not when connecting a passive TV with a set-top box, which uses an HDMI port as the only output (permanently connected and permanently active). I will take that risk. I have done this about 100 times in my life and nothing has ever happened. Of course, it was always about the usual connection of a set top box or, for example, a PC with a monitor/TV/video projector.
I do not need to provide more detailed information, because this problem is, according to everything, global. As I already wrote... you forget the fact that something is constantly being updated in Enigmas. Sometimes even the Linux kernel changes. If not the core, then the libraries are changed for newer ones, which are of course tied to these drivers, when using various functions. As I already wrote, there may be a compatibility problem.
I can turn on the DEBUG mode in Enigma2 and post this DEBUG LOG at the first nearest sound dropout error.
Posted 21 September 2024 - 17:59
I doubt you'll find something, but it's always worth a look.
There are never any kernel changes, only Edision ever updated a kernel for boxes already in production. Occasionally there is a defconfig update, if an additional kernel driver needs to be added, but that is about it.
And for drivers, VU+ hasn't made any updates in years, and now've they completely stopped making Open Source STB's and pulled the plug, I doubt we'll ever see an update again.
All AC3 dropout issues I've ever seen were related to protocol incompatibilities (apart from using the wrong cable spec), especially with the software in A/V receivers, and the issues increased with the more modern compressors used by broadcasters, and protocol updates like AC3+ and AAC.

Hi all.
Um... so it happened to me again, this time it wasn't AC3 but the MPEG audio codec (Vu+ Solo SE V2). The sound dropped out. And then everything behaved exactly the same as I described above - post number #26.
There was absolutely nothing in the debug log at the specified minute. Even +/- 5 minutes there was no entry in the debug log. The first entry in log-file after the sound droppped out was pressing the RCU button to switch the channel or to change the volume, which I already tried myself.
Posted 30 September 2024 - 20:38
You're sure it is not a provider issue? M7 had several issues with audio dropping out recently, which was confirmed using their own receiver.

The first time this problem arose was on the HBO channel (AC3 audio), which does not belong to the provider in my country, but there is a translation into another language.
The second time the problem arose on another Nova Fun channel (MPEG audio).
It is strange that I have this problem only on Vu+Solo SE V2. However, the problem does not occur on the Vu+Zero 4K.
I do not rule out an error in the HDMI cables. Or on TV (I should try another TV device). When turning on the audio amplifier in the same 230V socket as the set-top box, this problem with the audio dropout also happened once.
Posted 29 October 2024 - 20:51
Hello,
I have got a similar problem (if not the same) on my vu plus solo se V2.
Context:
Vu+ solo S2 V2 with dual T2 tuner.
Image: OpenPli 9.0 Version 20240701 (will upgrade to the latest see if changesomething)
Tv: Samsung connected in HDMI (no dolby between)
Symptom:
Sound stop working when watching tv at a moment. It could work a lot of day with no problem, then appear. (problem: when you are recording, you could not reboot, so it's finish you could not watch anything until record finish to reboot)
Nothing make it come back, only turn off or reboot will make it come back.
When sound disapear, you could watch previous record ==> No sound. You only have the video part, no audio.
All channel are e-AC3.
The previous rom i was using was an old openAtv 5.1 and i never have any audio problem with it, so it's not an HDMI problem or channel problem.
(i need to change the rom because of a subtitle problem that appear in some channel, something has changed there and in some channel it was not readable because text stay only 1s maximum, openpli 9.0 does not have this problem).
Is there any news to solve this problem?
Thank's

Hi @Linus.
BTW, aren't you a relative of the Linus Torvalds family ? :-)
I will disappoint you in that I also use the Vu+ Solo SE V2 with OpenATV. And there is exactly this problem. I can also confirm that there was no audio problem with older versions of OpenATV 5.x - 7.2. The audio problem, in my case, started sometime from OpenATV version 7.3 or 7.4.
However, I must note one more thing. For my ATV 7.4 and Vu+ Solo SE V2, everything is fine at the moment - it's been about 1 month... I haven't had any sound drop yet. But that could be a coincidence... it's possible that I'm not watching SAT channels that stream AC3 audio but only MPEG audio.
Maybe it has something to do with charging and discharging some static electricity :-D. I don't really know. And that might be related to some... driver... or some system library that affects the functionality of the drivers in Vu+.

Please note that e-AC3 hasn't been around for that long, chances are the drivers are from before that. so it could very well be because of flaky support for the new format in the old drivers. The fact only a reboot fixes it points also in that direction.

Hello,
of course not, i am not related to linus. 
I am a wish linus.
Thank you for the precision.
Do you know if openPli 8.3 have this bug?
It's my parents device to watch TNT and record, and i wanted to find a solution where they could watch tv 100 stable like it was in openATV 5.1 but with subtitle that work like in openPli 9.0.
I have already tested openAtv 7.X (do not know what was the stable version march/april 2024) and the problem of the subtitle in some channel was here too.
I don t know what have changed in some channel for this point that could explain that subtitle display only one second.
In openPli 9.0 it's pratically ok (except a subtitle problem when i fast forward) except for that AC3 problem.
Please note that e-AC3 hasn't been around for that long, chances are the drivers are from before that. so it could very well be because of flaky support for the new format in the old drivers. The fact only a reboot fixes it points also in that direction.
Hello
E-AC3 (or AC3+) is not really new, i do not found any date, but they where test in real in France for channel in 2006 and more test in 2009 and by default in all chanel since 2016, so it's before 2006.
But even if we could say it's recent, as overs said, that was ok on old rom and i never have any problem with openATV 5.1 for this point and it's somehting out before 2015.
They should be something that has been updated, that does not work with the old driver of vu+. Perhaps gstreamer or something like that, i do not test ServiceApp to see if it's better with serviceextplayer3.
I am not sure that the problem does not start when you have some problem of reception in one channel so a glitch/audio glitch that crash a pilote whereas before it does nothing.
(reception is good but i have got 2 channel that are not good when night is here). Of course switch channel or play anything do nothing after audio is lost.
I will try to switch to passthrough and come back when i lost sound to see if sound is back in passthrough and stay or not when come back to downmix.

I find this all very odd.
ATV 7.2 dates from the middle of last year, and at that time the VU+ Solo (no matter what flavour) was long End of Life. I think they've received their last driver updates in 2019 or so, so the drivers in ATV 7.2 are identical to those in later versions, or in OpenPLi 8 or 9.
So I maintain my suspicion that this is caused by a change in broadcasting (to something the drivers not completely support), and not by a change in software,

If it was a change in broadcasting, the problem should happen in all the image. Or that's not the case.
@PolarBear4711 roll back to 8.1 and does not have the problem again like it does not have before in this image.
If i roll back to the 5.1 i will not have the problem too. (i will only have the problem with the subtitle, that of course is something that change in the broadcast and is not correctly supported in openAtv 5.1 but correctly supported in OpenPli 9.0)
People that have the problem are talking about Sat channel, i am talking about France TNT so DVBT so not the same channel or way.
I am pretty sure that the problem is something related to compatibility between vu+ driver (if it's the only box that have the problem) and something like gstreamer or the way it is played.
That does not mean that something is wrong or bugged in enigma2, but just that something is different or use different part of driver that bring that bug, whereas before it was not using it or not this way.
