Service center employees are faced with customers complaining that their speaker is not working on their phone. The presented article reveals the causes of the malfunction and the most effective options for eliminating them. The instruction is suitable for both Android and iOs devices.
If the sound on the phone does not work, what should I do? It is necessary to determine the source of the problem. A list of them is given below.
- Audio settings are incorrect.
- The software installed is incompatible with the hardware.
- The user selected "quiet mode".
- Software conflicts.
- Debris has fallen into the polyphonic or earpiece speaker.
- The headphone jack is broken.
- Moisture has got inside.
- There is a breakdown in the hardware of the device.
Regardless of the time when the problem makes itself felt - when calling, playing music, you will have to carry out deep diagnostics.
Broken regulator
A polyphonic or conversational speaker in the phone will refuse to work fully if the owner first reduced the sound to a minimum and broke the regulator. The solution to the problem is to repair the swing. It is necessary to disassemble the case, check the current state of the contacts. If they come off, the master re-solders them or replaces the module with a new one. Buttons tend to jam, ceasing to function fully, probably debris got inside the mechanism. If a breakdown is found again, the side adjustment rocker must be replaced.
Note! To make the sound work when the swing is not functioning, it is recommended to use the settings menu. The operability will be restored, but such a solution to the problem should be considered as temporary.
Changing the volume in the setup menu
You can try to fix the malfunctions yourself by restoring the system factory settings. It is enough to click on the "Settings" icon located in the menu, select the "Volume" option (the name is different based on the current version of the operating system). A list of available profiles should appear, separate adjustments for the spoken and stereo speakers. You can set up playback on headphones.
After testing the volume controls and settings, check to see if the loudspeaker is functioning properly. Has nothing changed? We continue to check.
Audio board malfunction
Inside the smartphone there is an audio card that amplifies certain frequencies. A breakdown can provoke various consequences. Most often, the volume will be zero. The sound quality ceases to please the owner of the smartphone - some frequencies disappear.
Finding this on your own will be extremely problematic. It is best to find a service center where they will carry out diagnostics and repairs.
Mechanical damage
After a fall, both the loop and the sound card suffer. Usually, a damaged connector is completely replaced, because the cables have suffered from breaks that cannot be repaired, or the contacts are covered with small cracks.
The device is not insured against water penetration. First, let it dry for a while, then proceed with the repair.
Speaker malfunction
It is quite possible that the reason is a factory defect. With a valid warranty, it is necessary to carry out repairs or replace it with a similar copy. The component usually breaks due to impact. If a foreign object has got inside, which in parallel has destroyed the protective mesh, it should be completely replaced.
Audio jack problems
One of the reasons may be the failure of the contacts for the headphones. The smartphone will think that they are connected to the device, so a signal will be sent to the damaged pins of the connector. You can try to restore your working capacity at home. It's simple - we clean the connector and try to play the music again. Debris accumulation can also affect functionality.
Software level crashes
Conflicts on the software side appear due to the simultaneous use of several applications for mobile phones designed to correct the playback of audio files. If there are really too many of them, you need to do a few steps to go into the settings, leave only one program responsible for the sound, and delete all the rest. Next, we restart the smartphone.
Conclusion
Problems can be of different nature. Simple breakdowns can be repaired by yourself. If there are problems with the hardware, you will have to use the help of specialists. Using specialized equipment, the source of the problem is quickly checked. Further, a full recovery is carried out. To prevent a recurrence of such a situation, you should set the optimal settings in advance using the smartphone menu, use one profile from time to time to clean from dirt.

If the sound of an incoming call disappears on your smartphone, do not rush to contact the service. The problem is often solved on our own. But in order to choose the appropriate way to fix the problem, you need to find out the reason for its occurrence.
The most common reasons for the disappearance of sound
Most often, the reason for the disappearance of sound is not system failures or problems with the device, but trivial errors in the settings.
Volume level at minimum
Incorrect volume setting is the most common reason for no sound on a call
To fix the problem, press the volume up button and move the slider to the right to the maximum value. Make sure that the level of the other signals is also normal. Click the icon to the right of the slider. The volume levels of all signals (ringtone, media and alarm) will open. If there is no icon, then go to the phone settings in the "Sound" section and increase the volume of each of the signals.
Sound is in vibration or silent mode
Sound settings on android are located in the "Device" tab
Sometimes the sound accidentally switches from normal mode to vibration or mute (quiet). Go to sound settings or system profiles and select another mode.
Android software glitch
The sound may also disappear when a glitch occurs in the software... You can try to fix it by restarting your phone.
The person calling you is on the "black list"
The principle of removing and adding a person to the blacklist is identical on almost all smartphones with the Android system.
Sometimes, by mistake, you can add a person to the "black list" (block all calls from this contact). As a result, the subscriber calls, but cannot get through. In this case, there will be no sound of an incoming call.
To make sure that the caller is not included in this list, go to the "Contacts" section, select the person you need and open the menu of this contact. Select "Remove from blacklist" or "Unblock".
Speaker failure
Replacing the speaker on budget models can cost an average of 1000 rubles
If there is no sound in all programs and applications, not just during an incoming call, try connecting headphones. If sound appears in them, it means that the speaker is most likely damaged. To replace it, it is better to contact a service center.
Other reasons for no sound from an incoming call
If, after checking all the settings and the speaker, the sound problem is not resolved, look for the problem deeper.
Wrong firmware version or failed update
To return to factory settings, in the off state, simultaneously press the power button and the volume up button, then select Hard Reset
If the sound disappeared after flashing or updating the phone, then the problem may be that the service responsible for the sound is turned off:
- Go to Settings and open the Applications tab and Application manager.
- Find the sound service among the running applications and processes, open it and enable it if necessary.
A more difficult case is when a new firmware or update lacks the necessary drivers for your phone's speaker. Then you will need to roll back the firmware or reset the system to factory settings. This will delete data from the phone memory, so it is recommended to back up your data first.
To return to the previous firmware, you need to download it from the Internet, and then reflash the phone again.
It's easier to reset your phone and Android version to factory level. To do this, go to "Settings" and select the "Restore and reset" section. All data from the internal memory will be deleted (but not from the memory card), and you will receive the phone in the same condition as when you bought it. Then, from the previously created backup copy, move all the information to the phone, and all data will be restored.
Installed apps conflict with smartphone software
The sound of the incoming call may have disappeared after installing a new app. In this case, the problem can be solved by uninstalling recently installed applications one by one or by digging into their settings. For example, messengers, Skype, Viber, navigation applications have a function to turn off notifications and sound. In this case, the sound of an incoming call may also disappear.
Install programs on your smartphone only from trusted resources, preferably from the Play Market. It is also helpful to install an antivirus that will block malicious files.
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.
In addition to communication, there are many other functions on modern mobile devices. So with their help, you can listen to music, watch movies, play games, use various applications. All of this entertainment will be less interesting without accompanying audio effects.
Let's try to figure out why the sound on the phone does not work? What can cause this kind of malfunction and how can it be eliminated? Although all mobile phones have their own device, common symptoms of problems are observed with all models.
Signs of missing or unstable sound
Let's consider the main signs by which it can be argued that the audio signal has disappeared on the mobile.
- the first sign, no doubt, can be called the complete absence of any sound signals;
- during a conversation, you can hear extraneous noises or creaks coming from the speaker;
- the interlocutor's voice periodically rises, then falls or is interrupted;
- melodies are not produced or sound changes, crackling sounds are heard.
If the signs are not so obvious or happen periodically, this can mean both an accidental failure and the beginning of the speakers or other parts of the cellular device coming out of standing.
Let's check
To figure out why the sound in the phone does not work, you do not have to immediately run to the service center. Perhaps the cause of the problem is commonplace. To do this, you should first of all 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 submenus responsible for audio accompaniment.

Volume control
The first thing to do if you have a problem with poor sound on your mobile is to check the regulator.
It is usually located on the right side of the cell phone case. There can be several types:
- in the form of a solid button. The sound is adjusted depending on which end is pressed. On the one hand, it decreases, on the other, it increases;
- as separate buttons with plus or minus signs.
Make sure the slider is set to the desired 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 the adjustment exactly at the time of the conversation or when calling.
To increase the sound when playing video or music, as well as in games and applications, adjustments should be made with open media files.
Volume in the setup menu
If external adjustments do not work, it is possible that the reason lies in the system settings.
To check, you need to do a few things:
- go to the "Menu" section on your device;
- in the window that opens, find the subsection "Sound";
- on the "Volume" tab, move the slider in the desired direction.
By these actions, we will increase the overall audibility of the phone. As with the external control, the sound settings can be divided into separate parameters: for multimedia, for conversations. Adjust the required items depending on the symptom of the problem.
The reason for the silence can also be set to 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, then the problem can be resolved.
The main causes and methods of elimination
If checking the regulators and system settings did not fix the problem, then the reason lies elsewhere. These can be both software failures and mechanical damage or breakdown of one of the device's parts.
Accordingly, depending on the type of malfunction, there is also a method for its elimination. In some cases, you can do on your own and with a little manipulation, and sometimes you cannot do without the help of a master.
In any case, first of all, you should find the original source of the breakdown and only then decide how to eliminate it and whether it will be advisable to do this.
Broken speaker
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 other for conversations. If no sound is produced from any of them, then, most likely, the problems lie in other reasons.
One of the simplest ways to check if the earpiece is broken is to switch the conversation to the speaker. If the interlocutor can be heard well, it means that a breakdown has been detected.
Types of breakdowns and ways to solve them.
- one of the reasons for the deterioration of hearing from the speaker may be its clogging. The sound in such cases is reduced, but does not disappear completely. You can try to clean the speaker with a fine needle, cotton swab, or toothbrush. This is best done with compressed air;
Important! The main thing is not to overdo it and not damage the membrane during cleaning.
- a short circuit occurs in the speaker coil or it is burnt. It is difficult to hear a person or sometimes crackles. It is solved by installing a new spare part;
- an open circuit has occurred in the coil. The sound cuts out completely. Can only be corrected by replacing the component.
Important! In cases of decreased audibility in a mobile device, problems with the speaker occur in 80% of cases.
Sound amplification circuit malfunction
It often happens that the sound amplification circuit of a mobile device fails. In such cases, by adding or decreasing the volume, the audibility will not change. It is quite difficult to fix this problem on your own. It is best to contact a service center, where they will carry out diagnostics and replace the amplification circuit.
The reasons why the amplification circuit may burn out:
- mechanical damage;
- when the mobile phone is working in a highly overloaded mode and at the same time its temperature has risen significantly;
- liquid ingress;
- factory malfunction of the amplification circuit.
Broken train
One of the most common breakdowns is the failure of the loop. Most often, such a malfunction occurs in sliders and "rosettes". Since every time the device is opened, the loop itself moves, which leads to fraying of the contacts.
The main symptoms are the loss of audio signals and the failure of the volume controls. When replacing the part, all problems should disappear.
In addition to rubbing the loop connection, physical damage or moisture on the contacts can also lead to its malfunctions.
Software glitch
The number of useful applications for mobile phones is increasing every day. Unfortunately, not all of them pass a sufficient level of testing for compatibility with various models of mobile devices. Not to mention the deliberately harmful programs.
Some software glitches can simply be fixed by uninstalling the installed application. Some require a factory reset. More complex conflicts that set off a chain of failures will require flashing your cellular fixture.
Mechanical damage
They happen quite often. Not every apparatus can withstand being dropped or hit by a heavy object.
Mechanical damage can be conditionally divided into three groups:
- external malfunctions. If dropped, the speaker or volume control may be damaged. In this case, replace the visible defective part;
- damage to microcircuits. After a blow, both the loop 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 is necessary to disassemble and then understand which element is damaged and, if possible, repair it or replace it;
- cracks in the main board. Worst of all options. Depending on the model of the device, it may be more expedient to buy a new mobile phone than to repair it.
Pollution
Dust or fine debris on the phone contacts may burn cards or parts. An easier option is contamination of the outer parts. This can be a speaker mesh, which can be cleaned to remove a negative effect.
It is better to do cleaning with special devices and tools, and even better, entrust this business to professionals.
Moisture got in
Rain, snow, dew or any other liquid that gets on a mobile phone is unlikely to prolong its life. This also applies to any parts of the device responsible for the reproduction of audio signals. Excess moisture can burn out any components or oxidize contacts, which ultimately will lead to the loss of voice or music.
If you managed to notice the problem in time, then the consequences can be minimized. You should turn off the phone, carefully disassemble it and put 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.
Loss of sound on the phone is certainly an unpleasant situation, but in no case should you panic. Perform an initial test of the volume controls and settings in the menu. Then check the various programs and applications that may mute the volume or cause a crash.
If the malfunction lies inside the device, then it is better to turn to professionals who will carry out comprehensive diagnostics and return the functionality of your mobile device without any problems.
If the phone has lost sound, the reasons may be hidden both in the hardware and in the software of the device. Some are eliminated simply by changing the appropriate settings, but if the individual modules responsible for sound reproduction are abnormal, the gadget will have to be repaired in a specialized workshop.
Let's figure out how to independently determine the reason for the lack of sound in the phone and, if possible, restore all its functionality.
Checking the sound level setting
If you experience problems with sound, be sure to check your phone settings first. To do this, just press the button responsible for adjusting the volume of the gadget. If, when you press the corresponding key, you see that the volume scale is set to maximum, but the device does not make any sounds, you can proceed to troubleshooting.
Sometimes it happens that the audibility of the call melody or system sounds is quite satisfactory, but the interlocutor's voice is not heard. The reason may be quite simple - during a conversation, the user accidentally pressed the volume rocker and set the minimum value for the sound level. You can restore the previous settings in the same way while making a call or during a conversation.
Speaker malfunction
If everything is in order with the gadget's settings, the reason may lie in a serious hardware malfunction, for example, a speaker breakdown. Usually, this problem can be solved only at the service center by replacing the specified module. But here you need to take into account that the vast majority of devices have two or even more speakers.
One of them can be responsible for playing music in various applications and games, the other is responsible for the audibility of the interlocutor during a conversation. Therefore, if the sound in the device disappeared both in applications and during a call, then the reasons are most likely different. And the speaker malfunction can be easily checked by turning on the speakerphone during a call. If after this the interlocutor becomes audible, it remains only to go to the service and point there to the failed module.
The reasons for the breakdown of the speaker of the phone
By the way, the incorrect operation of the module in question can have various reasons:
- Clogged device. In this case, the sound often does not disappear completely, but users notice a significant deterioration in audibility. The part just needs to be cleaned, for which it is not necessary to take the phone to the workshop. When cleaning, you can use a toothbrush or cotton swab. The main thing is to be careful, otherwise the membrane may be damaged.
- Speaker coil burnout or short circuit. This breakdown can be indicated by a slight crackling sound that the user hears from the sound reproducing device, while the interlocutor can be heard. The problem is solved only in the workshop by replacing the burnt part.
- Breakage in the coil. In this case, the sound disappears completely, the part will also have to be replaced with a working one.
Audio jack problems
The check can be done after connecting the headphones. If you hear sound in them, try the following:
- insert and remove the headphone plug several times;
- blow out the audio connector with compressed air;
- if any liquid gets in, partially disassemble the device and clean the button contacts.
with headphones connected, hold down the volume up button and remove the headphone plug from the jack;
Also, the "antennae" are sometimes clamped in the audio jack, which indicates to the device that headphones are currently connected, why it does not give sound to the speakers. In this case, you need to try to unclench them, or give the device to specialists.
Sound Amplifier Board Problems
Sometimes the volume control button of the device stops working. This can be caused both by debris getting under the key, or by a more serious malfunction - the failure of the sound control circuit. It is quite difficult to independently determine whether this breakdown really takes place, therefore, in the described case, it is better to immediately diagnose the device in a specialized service and replace the board.
It is also useful to understand the reasons why gadget amplification schemes usually burn out. This could be:
- moisture penetration into the device;
- extreme heat from overloading a large number of applications, etc .;
- damage due to mechanical impact or factory defect.
Broken loop
If you are using a clamshell phone or a slider phone, then one of the probable reasons for the lack of sound may be a broken cable. When opening and closing the lid of the device, this element also starts to move every time, as a result of which, after prolonged use, the contacts may rub.
