Why is there no sound on the console. How to fix no sound from a flash drive when connected to a TV

Many buyers of DVB-T2 digital tuners were incredibly happy about the fact that these devices are equipped with a USB port and allow you to play music, photos and videos from a USB flash drive. In fact, if you decide to buy a DVB-T2 tuner, you will also get a media player!

As always, in a barrel of honey (not so sweet, by the way) there was also a fair fly in the ointment. New owners of DVB-T2 tuners notice that in many cases they play video without sound. Since the days of silent films have already passed, this state of affairs causes a certain misunderstanding among people.

Why is there no sound when playing T2 video tuner from USB?

In fact, the problems with sound (more precisely, with its absence) are explained very simply: our digital DVB-T2 tuners support encoding of the audio track in MP3 format, while many films contain audio encoded in AC3. The problem lies precisely in this and now can be solved in several ways.

The first way is to output audio via the S/PDIF connector using a separate audio playback device or a hardware converter.

If you look closely at the back of the STRONG SRT 8500 tuner (and others), you can see that in addition to the usual “tulips” (red, white, yellow sockets), there is also a specific S / PDIF output (Sony / Panasonic Digital interface), for digital audio output. The trick is that the tuner itself is not able to decode sound in a format that is not supported, but it can transfer it further to the device, which can handle this matter.

It's clear that such a decoder costs a certain amount, and you also need to know where to look for it. The easiest way is to buy S/PDIF decoder on eBay.com from our Chinese friends. Is the price of the question comparable to the price of a DVB-T2 tuner?

If your tuner does not have an S/PDIF output, like the Trimax TR-2012HD, you can try connecting it to your TV via HDMI. There are also no guarantees here, but there is a chance that this matter will be somehow fixed in the new DVB-T2 firmware.

Option number two requires a computer and a program like VirtualDub (or any other video transcoding program). You will also need some PC skills, or a friend who has such skills.

The essence of this method is as simple as doors: we take a naughty file and recode its audio track into mp3 format. In order to save time (transcoding can take a very long time, especially on a PC with a top-end configuration), you can set up transcoding only audio and direct copying of the video stream in the VirtualDub settings. But that's a topic for another article.

When watching interactive TV from Rostelecom, sometimes there are problems due to the fact that there is no sound on the set-top box. Their sources can be varied, as well as solutions. Often, you can fix the problem yourself. In some cases, professional advice from a technical support specialist helps.

From Rostelecom, has been provided for several years now. Her supplier is constantly improving the system, trying to improve quality. However, this does not mean that you can be 100% insured against force majeure situations. Users sometimes have a question, how to adjust the sound on the Rostelecom remote control? Let's try to understand this issue.

Reasons for no sound

When launched, provided by Rostelecom, no image appears on the screen, no sound either? There is a high probability that the channel is overloaded, the insulated wire is damaged. The malfunction may be due to the repair work carried out by the provider itself. Practice shows that it is repair or maintenance that causes problems with broadcasting, as a result, subscribers “enjoy” the poor quality of the picture, sound, and sometimes even their absence. To figure it out, it makes sense to make a call to technical support.

As for the situation when the sound does not work from the Rostelecom remote control, it can suddenly arise for everyone, even if there were no problems with audio playback before. Here you need to use the elimination method, check if the cable is disconnected or the connectors have poor contact with the connectors. It even happens that the user himself did not intentionally turn on the “silent” mode. It would seem that these are trifles, but they are most often the reason for the lack of sound accompaniment of the displayed picture.

There are different ways to solve the problem when there is no sound on the Rostelecom TV set-top box:

First of all, try restarting the equipment, namely the set-top box or router itself.
It does not hurt to check the cable connections to make sure they are tight. You are required to completely disconnect them, and then connect them.
Using the remote control from Rostelecom, you can solve the problem of non-working sound. Reset the settings to factory settings, and reboot the TV. Practice shows that modern TV models sometimes freeze. is carried out through the console menu, access to it is carried out in two ways.

We determine the performance of the console from the set-top box

When there is no sound on TV Rostelecom, you need to exclude all possible causes. If we talk about a remote control device, the first thing to check is its other options - whether the channels are switching. Pay attention to whether the red diode on its end part is lit. Keep in mind that light bulbs may not be visible to the naked eye, using your phone's camera is a great solution.

Are you sure that the batteries are working, but the bulbs do not react in any way? Perhaps the Rostelecom remote does not switch the sound due to its failure. In such a situation, one cannot do without contacting the company's office, where specially trained people will carry out diagnostics. You can specify the address of the nearest branch by phone, on the official website of the company. In addition to the faulty remote control, do not forget to grab your passport, you will be provided with other equipment during the repair.

It also happens that while the master is nearby, everything functions normally, but upon his departure the situation changes. So, if the sound has disappeared on the Rostelecom TV, there may be no synchronization between the remote control and the set-top box. This can happen after a hardware failure, the problem is solved by reprogramming a specific device. The essence of the procedure is to install a special code, upon recognition of which data changes are transmitted.

Continuing to talk about how to adjust the sound on the Rostelecom set-top box, I would like to say that you can change the settings in various ways. If you are leaning towards automatic, then nothing complicated will have to be done. Turn on the TV, and at this time on the remote press OK + TV. Next, you need to wait until the LED blinks 2 times, release the buttons, dial the combination 991. Thus, the device is switched to a special mode. At the next stage, press CH + until the TV turns off, this will mean that the synchronization code has been successfully selected. The final step is to hold down the OK key until the diode blinks twice to confirm that the settings have been saved.

Despite the actions performed on the Rostelecom set-top box, there is still no sound? Try to configure in another way - manually. In technical support, you can find out the synchronization code of the installed equipment. It will be enough to name the model of the TV. You can do this yourself, namely using the official website of Rostelecom.

Setting up the Rostelecom remote control in manual mode

On the company's website, go to the "For Yourself" section, select the item Television - Equipment. At the bottom of the page there will be an image of the remote control, below is a link to download a document with unique combinations. For each device model with a screen, there are several options. All other actions with the remote control are similar to those performed during automatic setup, the difference is only in the manual entry of codes.

Don't know what to do when the sound on the Rostelecom set-top box disappeared? You may need to completely reset the remote settings. To do this, activate the reprogramming mode, and then dial the numbers 977. After the Power key flashes 4 times, the changes made to the settings will be deleted. If all the measures described above did not work, then it makes sense to contact a company specialist.

When watching Rostelecom digital television, a problem may arise - the sound is gone, but there is an image. What to do in this case? First of all, you need to find out the cause of the problem

Why can the sound disappear on the set-top box?

If the sound is lost while watching IPTV television, then the problem may lie in the congestion of the channel, or the cable damage caused the problem.
Also, the sound may disappear due to the fault of the provider. For example, some technical work is being carried out on the line, and this may cause loss of sound or picture.

You can find out if any work is being carried out by calling the operator. It is advisable to make a call to the number of the regional or city representative office, which can be found on the website of the provider Rostelecom.

You can solve the problem associated with channel congestion by reducing the flow of downloaded materials via the Internet, or by disconnecting unnecessary devices from the network (phone, tablet, laptop, and so on). It will also help to avoid the problem of changing the tariff plan for the Internet to a faster one.

The sound while watching TV may disappear quite suddenly. To find out the reason, you need to act by the elimination method:

disconnect the cable, check it for integrity, reconnect;
check the contact of the connectors;
check the settings, perhaps someone accidentally pressed the "Mute mode" button on the remote control.

If everything is in order, but the sound did not appear, then you need to call the operator to find out the possible causes of the problem.

How to fix the problem yourself - no sound on the Rostelecom set-top box?

To fix the problem, the help of specialists is not always required; in most cases, users themselves can cope with the trouble. For this you need:

Restart the TV by removing the plug from the socket. The fact is that some modern models often freeze;
reboot the set-top box and router;
reset the equipment to factory settings;
disconnect and reconnect the cable.

Most often, it is resetting the settings that helps to cope with the problem. To reset the settings, you need:

go to the console menu, go to the "Settings" item;
select "System settings", in the menu that opens, go to the option "Restore factory settings";
confirm the operation by pressing the "agree" key.

You can also reset the settings through the service menu, this is done as follows:

you need to turn off and turn on the set-top box;
hold the "Menu" button on the remote control;
depending on the model of the STB set-top box, select Factory Reset/def setting;
save the selected parameters and reboot the equipment.

With the help of such simple operations, you can easily and quickly resume the sound of the set-top box.

What to do if the sound from a flash drive connected to the set-top box does not work?

The set-top box itself often has a connector for a USB device, which is quite convenient for watching downloaded movies.

The ability to view recordings directly from the media has become available recently. Initially, the provider offered its users a place in the cloud storage, where files were transferred from a USB drive.

On the provider's server, the content was automatically formatted with a codec and a container, only after that it was possible to view the recordings from the flash drive on the TV.

The disadvantage of this method was a heavy load, which could take more than a month to format one file. In 2013, to eliminate this inconvenience, the company decided to disable the automatic formatting system.

If the video from the flash drive has no sound on the Rostelecom set-top box, to solve the problem, you should reformat the file using a different codec and try to start playing again.

Set-top boxes from Rostelecom play videos with codecs:

264 (ensures small size while maintaining high quality);
MPEG-2 (an outdated codec that has less significant compression ratios);
MPEG-4 (a group of codecs that includes H.264).

The files on the set-top box use AAC and MPEG-1 encoding technology. The ideal container for recordings is "mp4".

If the subscriber encountered a lack of sound on the set-top box from Rostelecom while watching TV, and none of the above described helped, it will be necessary to contact the provider's technical support for help.

When calling, the operator needs to tell about the problem, the time of its occurrence and the procedures being carried out in an attempt to resolve the error on their own. Perhaps the operator will help remotely.

No sound on TV with Rostelecom prefix

If, when you turn on the IPTV set-top box from Rostelecom, there is no image on the TV screen and there is no sound, most likely the reason is the congestion of the channel or. Such malfunctions can also be caused by failures on the operator's side. For example, if the provider performs repair or maintenance work, errors occur in the broadcast, and the subscriber observes poor picture and sound quality.

In order to find out if the service has become a source of failures on your equipment, it will not be superfluous to call the customer support service, where they will confirm or exclude this option.

Attention! You can eliminate heavy congestion of the Internet channel by reducing the download speed and adjusting the traffic.

Why might the sound disappear?

The sound may disappear suddenly, even if there were no problems with audio playback before, and no prerequisites were noticed. In order to understand the cause, it is necessary to act by the method of elimination.

Among the possible options for the absence of sound, the following may occur:

disconnected cable;
poor contact of the connector connector;
turning on silent mode.

Accidental pressing of a button, touched wires and careless handling - all these little things become the reason why the sound may disappear on the set-top box from Rostelecom.

Attention! To avoid the occurrence of malfunctions of the device, it is recommended to periodically turn off the set-top box from the network for automatic.

How to solve the problem with the lack of sound on the Rostelecom set-top box

If there is no sound when watching television from Rostelecom, you can solve this problem using one of the following options:

reboot the equipment (set-top box and router);
check the cable connections (disconnect and reconnect);
reset the set-top box to factory settings;
reboot the TV (modern TV models sometimes freeze).

Quite often, it is the return of the settings to the factory level that helps to eliminate the failures that have appeared.

In order to reset, you need:

enter the console menu;
go to "Settings";
find "System Preferences";
select the line "Restore factory settings";
click "OK";

There is a reset option through the service menu, which is performed as follows:

turn on the attachment;
hold the "Menu" button on the remote control;
depending on the model of STB attachments, select Factory Reset/def setting;
save the selected parameters and reboot the equipment.

Thanks to simple manipulations, you can restore the normal operation of the console.

There is no sound from the video from the flash drive on the Rostelecom set-top box

On the body of the set-top box, you can see a connector for a USB device, which suggests the idea of using it.

The ability to view recordings directly from the media did not become available immediately. Initially, the operator offered its users a place in the cloud storage, where files were transferred from a USB drive.

On the provider's server, the content was automatically formatted with the required codec and container, after which it could be viewed on a TV. The only negative was the excessive load, which could take more than a month to format one file. Therefore, in 2013, it was decided to turn off the automatic formatting system.

If you encounter a problem when the video from the flash drive does not have sound on the Rostelecom set-top box, to solve it, you should reformat the file using a different codec and try to start playing again.

The device from Rostelecom plays videos with codecs:

264 (ensures small size while maintaining high quality);
MPEG-2 (an outdated codec that has less significant compression ratios);
MPEG-4 (a group of codecs that includes H.264).

The audio tracks and files on the set-top box use AAC encoding technology as well as MPEG-1. The optimal container for recordings is "mp4".

If there is no sound on your TV when watching IPTV from Rostelecom, do not rush to contact the service for help. Usually, you can solve the problem yourself. When difficulties arise or there is no desire to delve into the situation and look for the causes of the malfunction, you can consult with a specialist or call the master at home to eliminate equipment malfunctions.

There are many reasons why there is no sound when watching a video from a flash drive on a set-top box: in some cases, the problem is related to the incompatibility of the device with the audio codecs built into the media file, in others, to the limitations imposed by the interface used to connect.

The article will describe in detail each of the possible variants of the malfunction, as well as analyze the algorithm of actions to eliminate a particular problem.

Most often, the digital set-top box does not play sound due to the incompatibility of the software installed in the device with the audio codecs that are used in a particular video file.

If the on-air signal contains only audio tracks encoded in accordance with the standards, the decoding of which is within the power of any certified media player, then there are no uniform rules for packaging the soundtrack for content distributed on the Internet.
Budget set-top boxes that are not equipped with a Dolby Digital track decoding system are capable of playing stereo sound in PCM, AAC and MP3 formats - the DD family codecs will be ignored by the player, as a result of which only the video sequence contained in the file will be played.

On the other hand, the problem of the lack of sound does not only apply to cheap receiver models: although Dune's advanced devices are capable of decoding multi-channel codecs on their own, these devices sometimes refuse to play audio.

The vast majority of set-top boxes only support 44.1 GHz sampled audio, which is "traditional" but not reference.

If the user tries to play a video file with audio on the tuner, the sample rate of which is, for example, 48 GHz, the device will either refuse to play the soundtrack or start playing the sound at a very low volume level setting.
Another possible reason for the lack of audio when playing a movie on a TV from a flash drive is the presence of several audio tracks in the media file, one of which is damaged.

No “smart” set-top box is capable of analyzing the sound amplitudes of the soundtracks being played, and therefore the device always starts playing a track randomly selected from the array - if the selected track turns out to be defective or empty, the tuner will start “playing” silence.

It is worth saying that when faced with such files, even an advanced player that supports frequency analysis can fail.
The fourth reason for the lack of sound when playing video content from a digital drive is the incompatibility of the connection interface with the audio codec contained in the file.

For example, the VGA channel does not support absolutely any soundtracks, and the HDMI cable may fail when working with multi-channel recordings.

How to solve the problem

In the previous section of the article, all possible reasons for the “disappearance” of audio tracks attached to films were described in detail.

The solution to the problem with the lack of sound depends on the nature of the malfunction, which can only be determined experimentally:

Incompatibility of the set-top box with the codec. The solution to this problem is to convert the audio track of the media file using computer utilities. VirtualDub is a free application for Windows, among the features of which there is a function of transcoding audio tracks: the user will need to load the video into the editor, and then simply save the file with new audio parameters. We recommend using “MP3 Stereo” as the output format of the soundtrack.
Incorrect sample rate. You can change the sample rate in the already mentioned VirtualDub - you will need to add “44.1 kHz” to the “MP3 Stereo” setting. It is important to note that after changing the sampling rate, the sound volume level may decrease - you can stabilize the audio track in the XMedia Recode application by setting the maximum volume values on the master channel. If the TV set is compatible with Dolby Digital codecs, you can simply activate the “HDMI RAW” mode in the set-top box settings and enjoy high-quality sound without converting media files.
Audio defects. If the TV does not want to play audio from a flash drive connected to the set-top box, then you should check the number of tracks packed in the media file. Movavi Video Converter is able to analyze the soundtrack for artifacts and automatically remove damaged sections of the audio recording.
Interface incompatibility with the codec. Sometimes there is no sound during video playback via a modern HDMI interface, but when a tuner is connected via an outdated RCA cable, audio starts playing automatically. In such a case, the user can choose between converting the audio track to a simplified format and using the new connection interface. Since the process of connecting the console to the TV is extremely simple, the cables can be used alternately.

Before performing manipulations with converting video formats and reconnecting the set-top box to the TV, the user is recommended:

check for sound when watching digital television;
make sure the volume settings are correct;
try to play a movie from a previously formatted removable drive;
connect external audio equipment to the set-top box through the audio output on the control panel and try to start viewing.

No sound on TV with Rostelecom prefix

If there is no sound on the Smart TV connected to the Rostelecom console while playing video from an external drive, you will have to use media file conversion.

In the case of this provider, the user will need to re-record the movie in the “MP4” format, which contains the audio parameters required by the set-top box.

Interestingly, until 2013, Rostelecom provided its customers with the service of automatically formatting video content in a proprietary cloud storage.

No sound on Tricolor console

The lack of sound on the Tricolor set-top box can be explained by a software failure: if there is a problem with the audio, the company's online consultants recommend first rebooting the console or resetting the firmware to factory settings.

To return the software to stock, you will need:

Open "Menu".
Go to the "Settings" section.
Select "Factory settings".
Confirm your choice and wait for the reset to complete.

If resetting the parameters does not give the desired result, the owner of the set-top box will have to contact the provider's service center for help.

Outcome

An independent solution to the problem of the lack of sound on a digital set-top box while playing multimedia from a flash drive is within the power of each user: the main thing is to correctly determine the cause of the malfunction and follow the tips presented in this article.
