Tricolor does not reproduce sound from a flash drive. Digital set-top box has no sound. Solving the problem of no sound on the Rostelecom set-top box

Dear friends, today we will try to resolve the issue of what to do if the TV from the flash drive does not play sound. Let’s not say that the problem is quite serious: the TV will not have to be taken to some specialist in the first stages. This should be done in case of obvious breakdowns, but more on that a little later. First, let's look at the proper operation of a storage and transmission device - a flash drive - on a TV.

You can fix the error with sound playback when watching TV by studying the cause of the problem.

Such ports are usually equipped with devices that belong to the Smart TV family or were released shortly before their appearance. That is, your TV may not be “smart” with Internet access via wireless communication, with the ability to download and run applications, but with USB ports where you can connect peripheral devices. Typically, users watch movies this way: they download them from the Internet on a computer, then transfer the data to a flash drive and play them on the big screen. This is really a very convenient thing.

But often people face the problem of playing movies or videos on TV. For example, a Philips TV does not reproduce sound from a flash drive, what should I do then? With what it can be connected? How can I fix this problem? Should I immediately run to the service center and scream about warranty repairs? We will get answers to all these questions further.

Watching movies on TV from a flash drive

First, let's figure out how the system for playing videos on TV from a flash drive works. Naturally, to begin with, as noted above, the user downloads the necessary video from the Internet (any method of obtaining the desired file is suitable - you can copy it from a disk or other source of information), then copies this document to a flash drive. After which the device can be connected to the TV using the USB port and the receiver can be switched to the inserted device.

To do this, press the Source button on the remote control and use the navigation keys to transfer the selection to our flash drive (its name will be there). Click OK and wait for the menu to appear. Usually on such TVs the program asks the user to select the type of files to open. For example, a menu may appear with buttons for “Videos,” “Photos,” and the like. We should select "Video".

Now the device system will scan the data on the flash drive. It will only display files with video formats. This is done for greater convenience for the user: if there are more than a hundred photos and only one movie on the flash drive, then imagine how difficult it will be to search for it among a huge number of other files.

So, we chose a movie, played it, but there is no sound on the TV when we connect a flash drive. And this is where your problems begin. But they can be solved, so don’t be upset, but get ready to fix what’s wrong.

Why is there no sound on the TV from the flash drive?

First, let's determine the reason for this behavior of the TV. The thing is that it simply doesn't support the audio codec built into the movie. What does it mean? Any video has several tracks: at least audio and video. And if the TV does not support the audio format that is in our film, but supports the video track format, then the user will see the picture without sound. Since we're already talking about tracks, it's worth mentioning that a video can have two audio tracks. Then try switching them using the remote control buttons (you can find out more in the TV user manual).

To avoid this problem, you need to check the downloaded file. Look at the format of its tracks and compare it with those supported by the TV. This list can be found in the user manual or on the manufacturer's official website. All you need is the device model name. That is, at this moment there should be no problems. Please note that the XviD format is most often used, as it is universal for all devices. Watch this point when downloading movies.

But what to do if the codecs are not suitable at all, and there is no way to download another movie? Then you can transcode the audio format to the one you need using third-party utilities. The following programs may serve as such:

• Total Video Converter;
• Virtual dub.

Naturally, it’s better to just download another video than to spoil an existing one. Moreover, such programs can take a very long time to do the conversion. Especially if you change the format of a video larger than two gigabytes in 1080p quality. Take this point into account too.

Conclusion

Dear friends, we found out why there is no sound on the TV via a flash drive and how to fix this problem. Summarizing everything that was said earlier, the following key points can be highlighted:

• Any video has several layers of tracks, so don't worry if you see the picture without sound.
• To play the file correctly, it is worth checking its support for the downloaded movie.
• The audio track can be re-encoded, but do not forget about the time spent and some loss of file quality. Therefore, it would be better to download the required file again correctly.

Please note that the flash drive you use must not contain any viruses. Therefore, first check it on your computer and only then insert it into the TV port.

ADVICE. If you are unable to watch a film even with official support for its format, then you should contact the manufacturer for help.

We hope everything worked out for you. Tell us in the comments how you overcame this problem, what remedies helped you?

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

The article will describe in detail each of the possible variants of the malfunction, and also analyze the algorithm of actions to eliminate this or that problem.

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

If the broadcast signal contains only audio tracks encoded in accordance with standards, the decoding of which is possible for 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 - 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 lack of sound concerns not only cheap receiver models: although advanced devices produced by Dune are capable of independently decoding multi-channel codecs, 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 run a video file with audio on the tuner, the sampling frequency of which is, for example, 48 GHz, the device will either refuse to play the soundtrack or start playing the sound with a very low volume 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.

Not a single “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 begin to “play” 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 storage device 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 soundtrack, and the HDMI cable may malfunction when working with multi-channel recordings.

How to solve a problem

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

The solution to the problem of no sound depends on the nature of the malfunction, which can only be determined experimentally:

1. Incompatibility of the set-top box with the codec. The solution to this problem is to convert the media file track to sound using computer utilities. VirtualDub is a free application for Windows, which includes functions for transcoding audio tracks: the user will need to load the video into the editor, and then simply save the file with the new audio parameters. It is recommended to use “MP3 Stereo” as the soundtrack output format.
2. Invalid sample rate. You can change the sampling frequency 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 frequency, 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 your television 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.
3. Audio recording defects. If the TV does not want to play audio from a flash drive connected to the set-top box, then it is worth checking the number of tracks packed into the media file. The Movavi video converter is capable of analyzing the soundtrack for artifacts and automatically removing damaged sections of the audio recording.
4. Interface incompatibility with codec. Sometimes there is no sound when playing video over a modern HDMI interface, but when you connect a tuner via an outdated RCA cable, the 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 to:

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

No sound on TV with Rostelecom set-top box

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

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

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

There is no sound on the Tricolor console

The lack of sound on the Tricolor console can be explained by a software failure: if a problem arises with the audio, the company’s online consultants recommend that the first step is to reboot the console or reset the firmware to factory settings.

To return the software to stock form you will need:

1. Open "Menu".
2. Go to the “Settings” section.
3. Select "Factory settings".
4. Confirm your choice and wait for the reset to complete.

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

Bottom line

Each user can independently solve the problem of no sound on a digital set-top box while playing multimedia from a flash drive: the main thing is to correctly determine the cause of the malfunction and follow the advice presented in this article.

As the manufacturer notes, periodic software updates on satellite receivers are necessary for the correct operation of the entire equipment system. A decrease in signal reception quality, as well as control problems, are inevitable. But, according to users, even after the planned firmware update, the set-top box begins to work incorrectly. An impressive number of owners lose sound on Tricolor TV; some note that after the update, the system becomes sensitive to power surges and turning on and off the lighting in the room, as well as other devices.

Let's try to figure it out together using the GS-8306 receiver as an example.

Common problems at work

The manufacturer does not provide clear explanations as to why the set-top box starts to malfunction after installing the updated software version. However, the consumer has to deal with the fact that the TV reproduces an unclear picture, the image “slows down”, and later may disappear completely. Sound problems also occur for most GS-8306 owners , and the most diverse.

About 40% of users complain that the volume becomes uncontrollable and can change independently without any participation, the remaining 60% complain that there is no sound at all. And it is not possible to change this using normal settings.

There is also a dependence on other equipment in the house. For example, the sound begins to disappear after turning off the refrigerator or kettle. However, the receiver itself may also be faulty. : display incorrectly or turn off unexpectedly. But the occurrence of such malfunctions is possible not only with the GS-8306 model. It is not always possible to update and then successfully launch the equipment in the case of other set-top boxes.

Getting rid of the consequences

The developers assure that the new version of the software will be released taking into account the problems that arose after installation, and such negative manifestations will be avoided. At the moment, programmers and engineers recommend not to panic and follow simple algorithm of actions, which will return the receiver to working condition:

If resetting and rebooting still fail to fix the problem with sound or picture quality, you may not be able to avoid contacting a service center. If the equipment is still under warranty, the company’s services will be free. Otherwise, diagnosing and reflashing the receiver will cost you from 350 to 1000 rubles.

User errors

As practice shows, digital satellite television does not always bring joy to the consumer. Sometimes buying a receiver involves resolving technical issues and purchasing additional equipment. The set-top box model GS-8306 is the most unfinished, according to the owners. The cause of malfunctions is not related to the device itself. According to the software developers of the mentioned receiver, the issue is solely in the incompletely finalized firmware. The next update will change the situation, as well as replacing the output cables.

Many users have been able to verify from their own experience that the purchase of new cables and surge protectors has a positive effect on the sensitivity of the equipment to power surges. Switching to the so-called “tulips” solves some of the problems with sound, including the problem with uncontrolled volume changes when watching some channels disappears.

But the problem is not always due to the update. Some owners GS-8306 from Tricolor TV are careless in handling the equipment and neglect the operating instructions.

An interrupted reboot is fraught not only with the loss of saved settings, but also with a decrease in controllability. An intermittently slow frame or obvious pixelation may be a consequence improper shutdown of the receiver, because spontaneous unplugging from the socket can lead to more serious consequences, even fatal failure.
