What to do if there is no sound on your smartphone. There is no sound in the smartphone (phone) or tablet on the Android platform. What to do and how to fix it? Problems with the audio amplification board
If there is no sound in movies on Android when watching, you need to check the volume settings, and also make sure that the video file and the player through which it is played are working properly.
This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
Reasons for the lack of sound in films on Android
The first thing to do is make sure that the volume is set at an acceptable level. Try playing another movie, use standard player or start a video on YouTube. Android has different volume settings for alarms, ringtones, and audio/video playback. Therefore, if there is no sound when playing a movie, it can work without problems, for example, on an alarm clock.
Increase
If other content plays normally, then there is a high chance that you downloaded the movie without sound. An error occurred when encoding the film, as a result of which the audio track was lost and was not added. You cannot eliminate this drawback on your own; all that remains is to download another file. Another possibility is an inappropriate file format. Your phone may not have the codecs needed to play it.
Increase Two solutions:
- Convert a movie to another format that is supported by the system and player.
- Install another player that can work with this format.
Some players offer to download missing codecs. It is too good decision, but if you agree to download additional files, connect to Wi-Fi to avoid unnecessary spending mobile traffic.
No sound on Android TV
If there is no sound when playing a movie via Android TV, then the first thing you need to do is check that the set-top box is configured correctly. The sound output method depends on the capabilities of the TV:
- When using a receiver or TV with built-in decoders, select RAW or Passthrough.
- On a simple TV, use PCM output.
Increase If the output method is selected correctly, but the sound does not work, reset Android settings TV and set the parameters again.
Users of mobile gadgets often encounter problems with sound deterioration on their devices. RosCase will talk about the main problems and advise what to do in a given situation.
As practice shows, the most common reason that the sound on the phone is lost is a change in the settings. Perhaps you just accidentally turned down or turned off the volume, and therefore your phone stopped informing you about calls through audio effects.
Go to the sound settings and set the volume to maximum. Then check the speaker operation. If everything is in order and the sound appears, then you panicked in vain - and now you can continue to safely use your device. If no changes occur, we recommend continuing to check the device to determine the cause of the failure. If you cannot identify the cause on your own, contact electronic device repair specialists.
Often the sound does not disappear entirely, but is simply distorted. The problem may be that the speakers have become dirty over time. And to clean them, it is not at all necessary to carry the device in service center. This can also be done at home. We'll tell you how to clean your phone's speakers and improve sound quality.
During operation, dust, dirt and small debris get onto the fine mesh of the speakers. A layer is formed that prevents normal playback sound signals. Cleaning will help here. To do this you will need alcohol and a toothbrush. Moisten it with a small amount of alcohol and carefully treat the surface of the speakers. All dirt should transfer to the bristles.
A very fine needle may also help. With its help, you can push the dirt and clear the mesh holes. Just remember that you need to do this very carefully so as not to damage the speaker itself.
Also check if the sound in your headphones works. If yes, then it really is a matter of dynamics. If the sound is reproduced perfectly through the speakers, but is not audible through headphones, the problem may be that the 3.5 mini jack input is damaged. With such a malfunction, it is better for you to contact a service center. This part may need to be replaced.
In some devices, the sound does not disappear completely, but begins to be reproduced with wheezing and noise. After studying many different forums, we came to the conclusion that we need to replace back cover if the speaker on your phone wheezes. You can also try widening the hole for the speaker. The aesthetic appearance may deteriorate, but the sound should improve.
Some users are faced with the problem of sound playback while watching videos. The reason may be the lack of the required codec on the device. Install MXPlayer - this program itself will recognize which codec is needed and download it from the network - and you can watch the movie with sound.
You don't know how to increase the volume on your phone and want to make it louder than the settings allow? Specially developed for such cases special applications. For example, the Volume+ program will allow you to increase the volume of the device, the bass level, and the sound of the call signal within a few minutes through simple manipulations. Just keep in mind that the louder the sound, the more distortion may appear.
Do you want to receive high quality sound without any wheezing? We advise you to buy speakers for your phone. They will increase the sound as much as you would like it to. Today there are a variety of wireless speakers. On our website you can different shapes, sizes, colors. Some have a call answering feature so you don't have to look for your phone to answer a call. A special button on the speaker will provide you with a quick answer to the call.
If your smartphone is in a case, then the speaker will be protected from dust and debris falling on its surface. Your gadgets will always be reliably protected in cases from RosCase!
Smartphones and tablets running operating system, at this stage of technology development and wireless networks, are first of all, multimedia devices. Millions of users around the world use their mobile gadgets to watch videos, listen to music and communicate online. in social networks and messengers. However, a situation may arise when you have no sound when watching videos or movies. We will tell you what it may be related to this problem and how to solve it.
Make sure the problem is in the video
Before starting any manipulations, you should find out whether the problem is only the lack of sound in the video or there is no sound at all. Try turning on music or going into settings and playing system sounds. Perhaps you just accidentally installed silent mode or lower the volume to minimum. If there is no sound everywhere (it is not in music, settings, video), then it is likely that the problem lies in the dynamics of the smartphone.
Lack of required codecs
Just like on a computer, programs for viewing video files on Android require special codecs for correct audio processing. You can try installing free codec packs from the official store Google applications Play.
Lack of AC3 codec
On personal experience I can say that most often there is no sound in large .mkv files in which the sound is encoded in AC3 format. The simplest and in a fast way The solution to this problem is to install the program. When playing a video file in this player, there is almost always sound.
If all of the above methods did not help and there is no sound in the video, then you can proceed to radical methods- resetting the settings and flashing the smartphone. However, before doing this, we strongly recommend checking whether the audio track is present in your video; try playing it on your computer.
The main purpose of any phone is to communicate with another person. If during a conversation the interlocutor is hard to hear or the speech is cut off and interference appears, then, accordingly, the usefulness of such a conversational device sharply tends to zero.
On modern mobile devices, in addition to communication, there are many other functions. So with their help you can listen to music, watch movies, play games, and use various applications. All this entertainment will be less interesting without accompanying audio effects.
Let's try to figure out why the sound on the phone doesn't work? What can cause this type of malfunction and how can it be eliminated? Although all mobile phones have their own device, but general signs Problems are observed in all models.
Signs of missing or unstable sound
Let's look at the main signs by which we can say that the audio signal has disappeared on the mobile phone.
- the first sign can undoubtedly be called the complete absence of any sound signals;
- can be heard during a conversation extraneous noise or creaks coming from the speaker;
- the interlocutor’s voice periodically rises, falls or is interrupted;
- melodies are not produced or their sound changes, crackling sounds are heard.
If the signs are not so obvious or occur periodically, this may mean either an accidental failure or the beginning of the speakers or other parts of the cellular device to fail.
Let's check
To figure out why the sound on your phone doesn’t work, you don’t have to immediately run to the service center. Perhaps the cause of the problem is trivial. To do this, you should first check the external regulators or check the settings in the mobile phone menu.
Both operations will not take much of your time. Although each mobile has its own design features, all of them have an external volume control and menu subsections responsible for audio.

Volume control
The first thing you should do if you have a problem with poor sound on your mobile device is to check the regulator.
It is usually located on the right side of the mobile phone body. There may be several types:
- in the form of a solid button. The sound is adjusted depending on the pressing of a certain end. On the one hand it decreases, on the other it increases;
- in the form of separate buttons with plus or minus icons.
Make sure the slider is set to the correct level. Move it if necessary. If the problem was in the regulator, then the adjustment should fix it.
In the normal state, the audibility of the bell and system commands changes. In order to increase the voice of the interlocutor during a conversation, you need to make adjustments precisely at the time of the conversation or during a call.
To increase the sound when playing video or music, as well as in games and applications, adjustments should be made specifically when open files multimedia.
Volume in the setup menu
If external adjustment does not bring results, it is quite possible that the reason lies in the system settings.
To check you need to do several steps:
- go to the “Menu” section on your device;
- in the window that opens, find the “Sound” subsection;
- On the “Volume” tab, move the slider in the desired direction.
By these actions we will increase the overall audibility of the phone. Like the external control, the sound settings can be divided into separate parameters: for multimedia, for conversations. Depending on the symptoms of the problem, make the necessary settings.
The reason for the silent sound may also be one of the modes of your device. There are “silent”, “quiet”, “on the plane” and others. Accordingly, if you replace one of these modes with a simple one, the problem may be resolved.
Main causes and solutions
If checking the regulators and system settings does not eliminate the problem, then the reason lies elsewhere. These could be either software glitches or mechanical damage or failure of one of the device parts.
Accordingly, depending on the type of malfunction, there is a method for eliminating it. In some cases, you can do it on your own and with minor manipulations, and sometimes you can’t do it without the help of a specialist.
Foo: no sound
In any case, first of all you should find the original source of the breakdown and only then decide how to fix it and whether it would be advisable to do so.
The speaker is broken
One of the reasons for the loss of any audio signals is a broken speaker. This is a serious malfunction and in most cases can only be solved by replacing the part.
It should be said that modern mobile devices have 2 or even more speakers. Usually one is responsible for music, games, applications, the second is for conversations.
If sound is not produced from any of them, then most likely the problem lies in other causes.
One of the easiest ways to check whether the speaker is broken is to switch the conversation to the loudspeaker. If the interlocutor can be clearly heard, it means that a breakdown has been detected.
- Types of breakdowns and ways to solve them.
One of the reasons for the deterioration of audibility from the speaker may be its clogging. The sound in such cases decreases, but does not disappear completely. You can try to clean the speaker using a thin needle, a cotton swab or a toothbrush. This is best done with compressed air;
- Important! The main thing is not to overdo it and not damage the membrane during cleaning.
- There is a short circuit in the speaker coil or it is burnt. It is difficult to hear a person or sometimes crackles. Solved by installing a new spare part;
there is a break in the coil. The sound disappears completely. It can only be fixed by replacing the component.
Important! In cases of decreased audibility in a mobile device, problems with the speaker occur in 80% of cases.
It often happens that a mobile device's audio amplification circuit fails. In such cases, when adding or decreasing the volume, audibility will not change. It is quite difficult to fix this problem yourself. It is best to contact a service center, where they will carry out diagnostics and replace the amplification circuit.
Reasons why the amplification circuit may burn out:
- mechanical damage;
- when the mobile phone is operating in a heavily overloaded mode and its temperature has risen significantly;
- liquid ingress;
- factory malfunction of the amplification circuit.
Broken cable
One of the most common breakdowns is the failure of the cable. Most often, such a malfunction occurs in sliders and clamshells. Since every time you open the device, the cable itself moves, which leads to rubbing of the contacts.
The main symptoms are loss of audio signals and failure of volume controls. When replacing the part, all problems should disappear.
In addition to chafing of the cable connection, physical damage or moisture on the contacts can also cause its malfunction.
Software glitch
Every day the number increases useful applications for mobile phones. Unfortunately, not all of them undergo a sufficient level of testing for compatibility with various models mobile devices. Not to mention obviously harmful programs.
Some software glitches can be simply fixed by uninstalling the installed application. Some require a factory reset. More complex conflicts that started a chain of failures will require reflashing your cellular device.
Mechanical damage
Happen quite often. Not every device can withstand being dropped or hit by a heavy object.
Mechanical damage can be divided into three groups::
- external faults. If dropped, the speaker or volume control may be damaged. In this case, the visible faulty part should be replaced;
- damage to microcircuits. After an impact, both the cable and the sound card or other fragile elements of the device may fail, the defects of which are visually impossible to see without opening it. You need to disassemble and then understand which element is damaged and, if possible, repair or replace it;
- cracks in the main board. The worst of the options. Depending on the model of the device, it may be more advisable to buy a new mobile phone than to have it repaired.
Pollution
If dust or small debris gets on the phone contacts, the boards or parts may burn out. An easier option is to contaminate the external parts. This could be the speaker grid, by cleaning which you can remove the negative effect.
It is better to do cleaning with special devices and tools, or even better to entrust this task to professionals.
Moisture has entered
Rain, snow, dew or any other liquid that gets on your mobile phone is unlikely to prolong its life. This also applies to any parts of the device responsible for playing audio signals. Excess moisture can cause any components to burn out or contacts to oxidize, which will ultimately lead to loss of voice or music
If you manage to notice the problem in time, the consequences can be minimized. You should turn off the phone, carefully disassemble it and leave it to dry.
It is advisable to wait a long time, since the desire to quickly check the operation of the device can lead to its final breakdown.
Losing sound on your phone is of course an unpleasant situation, but in no case should you panic. Perform an initial check of the volume controls and settings in the menu.
Then check various programs and applications that may be muting the volume or causing a crash.
