If E-AC4 isn't already implemented, I wouldn't count on any updates. Licensing issues, no matter how OEM it looks.

Check in the menu and in the soundtrack, if there are no - maybe the Audio track is set wrong or something...

I checked the soundtracks. Even when there are several to choose from in a given program, none of them work. There are no other sound settings. I noticed something strange, on another decoder, Events 24 has MPEG audio, and there is no audio either, and it used to be (before May 23, 2022). Of course, TVP1 programs; TVP2; TVPinfo etc. are doing well.

Of course you're talking about audio playback? Regards.

The picture in all channels is flawless, even perfect.
The only problem is with the sound.

At this link there are older firmware than the one I have. The devices in the photos on this page look different. Not sure if it's the same device. I didn't see the presentation program in mine. The firmware markings are also different. The only common feature is the H120 model.

On the old standard in which MUX-3 is broadcast, also?

h999 · Answer

I wrote earlier that TVP is doing well.

sabtron · Answer

Were you able to resolve this sound issue? I have the same tuner model and the same problem.

tomaszlonski · Answer

You probably won't solve the problem so easily now, this tuner is adapted to the Russian market and has support only for MPEG-1 and MPEG-2 Layer II, i.e. no support for MPEG-H (AC-3 and AC-4).

Just once again, it should be noted that most set-top boxes bought on Aliexpress do not meet the requirements of the standard adopted in Poland, usually they are not even intended for sale on the European market.

h999 · Answer

There are tuners with older software and they work. It's a matter of firmware, only where to download it. The tuner has many functions that were not dreamed of by tuners sold in Poland, all program parameters are displayed under one button on the remote control, everything works super smoothly, does not lose programs, does not change their numbering, there is YouTube, it plays files. I'm still looking for firmware.

tomaszlonski · Answer

I am improving, but some support for the new sound system at least for MPEG-2 layer 2 and 3 has only a problem with the firmware and switching to the appropriate system does not work thanks to the image being received.

Have you tested changing the region as it is in the settings for the Czech Republic or Germany?

Search the Czech and Ukrainian forums, maybe they will have 4pda, this tuner is more popular in the east. Unfortunately, I did not find the firmware

h999 · Answer

There are no regional settings. There is only software language change which doesn't change anything except the displayed language.

I found an update of such a tuner on YouTube: https://www.youtube.com/watch?v=Gsw6-wlxHvw
I downloaded the update file: evn1509c-115-0902_rom_all.bin from the address: https://drive.google.com/file/d/13nLlNtBzGG5QfwtG75LB3rTbQuZfm6-t/view
Unfortunately, the tuner does not see this file in the update. Maybe someone knows how to change the name to make it work. They must have messed something up so he can't see the update. It sees other files via USB but not in the update window.

wkaczma · Answer

And how did you deal with it?

h999 · Answer

I put the box in the box and I'm waiting for someone to solve this problem, I'm exhausted.

tomaszlonski · Answer

You are unlikely to solve anything, the chipset does not have hardware support for the required AC3 and E-AC3 audio format.

p.s. I can bet that programs recorded on the tuner and played on the computer have sound without a problem.

h999 · Answer

Actually, the computer plays with sound. But as I read about the firmware on foreign forums, this copy had AC3 in the second firmware release, and not in the last one. This would indicate a blockade of AC3 to the European market. That's why I downloaded the firmware for this model from Asia, but there is probably some trick with the extension or with the file name because the file is not visible in the firmware update window.

tomaszlonski · Answer

The second version is a tuner with a different processor and support. Under this designation there were several versions of this tuner for different models and sellers.
No new software will cause the operation of something that is not in hardware support.

h999 · Answer

Thanks, this is the first time I’ve seen different hardware under the same name. So it will treat the tuner as a recorder. Strange that they only broadcast audio in AAC and you can’t select MPEG. In the past, there were different sound encodings on TV to choose from, I checked old recordings, there is a lot to choose from.

h999 · Answer

Thanks for the concrete hint.
