We do not recommend getting into the inside of the device yourself, as it is easier to break cables, delaminate the display module, screw screws into the wrong place, or chip SMD elements than snap your finger. We do not recommend carrying out any work without relevant experience. Repeat everything described below only at your own peril and risk.
Disclaimer:
Please note: This article discusses the solution to the problem using the iPhone 5S as an example.
Causes of malfunction
At the moment, several reasons have been identified that cause a problem in the form of poor sound or its absence. Below we will study each point in detail and discuss ways to correct it.
Hard to hear when talking on the phone
If you find interference during a telephone conversation, then the reason may be related to mobile communications. Check for antennas at the top of the screen.
If the interlocutor is hard to hear, check the volume level on your smartphone and increase the volume to maximum. In case of a software failure, you should restart your smartphone or reset the settings to factory settings.
The third tip is to plug your headphones into the jack. If you can hear the person clearly and without interference, then the problem is hidden in the phone’s speaker.
The sound is completely gone
If there is no sound at all, it wouldn’t hurt to also check the volume level on your phone. Often, users may accidentally disable this setting. If everything is fine, then reboot the device.
If there is no sound only for incoming calls, then check the current mode. You probably set it to “Do Not Disturb” and didn’t change it back.
Make sure you have the setting disabled in Accessibility. Find this section in the settings and in the “Hearing” tab, disable the “Mute all sounds” function.

The last solution is to reset the settings to standard. But, this option should be done as a last resort. Remember if water got into the speaker, because it may be broken.
The speaker on your phone can easily fail if:
- It's clogged.
- Parts are burnt out or a short circuit has occurred. In this case, users hear crackling sounds.
- There is a break in the speaker coil.
No sound on SMS
Can't hear notifications when you receive a new message? Go to the notification settings and make sure that the melody is set for SMS. There may also be a software glitch that requires the device to reboot. No system is perfect, Android is no exception. Sometimes system errors may occur that affect the operation of other modules in the phone.
No sound on headphones
If there is no sound in the headphones, then carry out the standard checks described above. Make sure that the connection is not interrupted due to a poorly inserted connector, or that the phone is on sound. It is recommended to check the operation with other headphones; if sound appears, then the problem lies in the connected accessory. Play any video or music and check for sound through other headphones.
Be sure to check if the Mute feature is disabled in Accessibility Settings.
Glitch with headset
When working only on speakerphone, it happens that the phone freezes in the “connected” headset position. This situation is very easy to imagine if there is a huge amount of debris or moisture in the headphone jack. Try blowing the contacts well - maybe this will help (the phone should make the sound of the headset being disconnected).
By the way, the charging socket also contains contacts that transmit sound - so the advice is relevant for this connector too.
1-CONNECTOR
Have you ever wondered how your phone detects that headphones are inserted into it?
Everything is very simple: inside the connector there are two contacts specially designated for such needs. When these contacts are closed, the phone states that the headphones are inserted. At the same time, he, of course, sends the sound to the headphones and TURNES OFF the SPEAKER.
In order to reinforce what was said, I specially disassembled my phone, and I was surprised to find that its connector even has 7 contacts, despite the fact that the headphones only need 4.
So, don’t let this bother you, but very often the speaker does not work because the phone thinks that headphones are inserted into it and the speaker is actually just turned off.
This happens because the two contacts responsible for identifying the headphones in the connector are caught on each other. Often the opposite happens - one or both contacts break off. In this case, the phone will not see the headphones at all.
This usually happens due to very active use of headphones. But the key fobs plugged into the headphone jack contribute much more to killing the connector.
how to check the connector?
Many phones show a headphone icon. If it is constantly there, even when there are no headphones, then this is our case.
In addition, if the silent mode is not turned on, then even with headphones inserted, most gadgets will play the ringtone through the speaker.
Likewise, when you turn on the speakerphone during a call, with headphones inserted, the speaker should work. If so, then the problem is clearly in the connector.
If the speaker still doesn’t start singing, then the problem is related to it, then see point 2
what can be done with the connector?
As a temporary solution to the problem, you can try inserting and removing the headphones while pressing the connector sideways in different directions. But this doesn't always help.
A match with cotton wool dipped in alcohol can also help. It often happens that the contacts do not fall off, but simply become dirty. However, with such manipulations you need to be careful, because The fleece may begin to cling and wrap around the connector contacts and the remaining contacts may be torn out or bent.
If you managed to restore the connector, that’s good; sometimes after something like this, it can work properly for a long time. If this problem recurs regularly, then replacement is inevitable.
The top cable is faulty
The top cable on the iPhone (in 5S/5SE models) is responsible for the front (main, not front) camera, light sensor and earpiece. This means that if you cannot hear the interlocutor during a conversation or hear with great interference, there is a possibility of problems with the upper cable (the display does not go off during a conversation - from the same song). There is a replacement below in the text.
Important: If the phone has already been repaired, then you should pay attention to the cable gasket - is it in place? Unscrupulous servicemen do not put it in its place - without it, the iPhone begins to foul
The speaking (hearing) speaker is faulty
[a[adace-ad id=»5228"]p>
The speaker itself, if the phone has not been thrown or drowned, rarely fails. Usually it dies slowly - extraneous noise begins or it works too quietly (this could also be an audio codec - more on that below). The speaker looks like this:
It is located on the display module, next to the proximity sensor and front camera - its replacement must be done very carefully so as not to damage the parts. As we wrote above, the speaker is a simple element, and therefore a relatively reliable element in the iPhone. But there are problems with it too - defects, ingress of water, mechanical damage.
Let's take a closer look at the latter: inside the speaker there is a permanent magnet, an inductive coil on which a thin copper wire is wound, and a diffuser is attached to it, current is supplied to the coil and it is either attracted or repelled from the magnet, while the diffuser pushes the air and thereby creates sound waves - this is how we hear sound from a speaker
When struck, it happens that this wire breaks, the current stops passing and the speaker stops working. And if moisture gets in, the audio coil can oxidize, the contacts can rot, and the current simply won’t reach the coil. The fact is that the diffuser is made of thin flexible material, most often from pressed paper, but there are diffusers made of plastic and metallized paper, so this is a very fragile element - it is easy to damage
Special cases
It is worth paying attention to solving problems associated with the lack of sound, but which are less common.
The speaker does not work when talking
First, make sure that there is sound when you make a call using a headset. If there is no sound, start a conversation using the multimedia speaker (Speakerphone).
In case of problems with the speaker, you must use the services of a service class=”aligncenter” width=”650″ height=”363″[/im[/img]
Notification sound doesn't work
If the notification sound does not work, make sure that a profile is active that allows you to play sounds, or increase the volume by pressing the “ Volume + ” key.
If there are no changes, you should make sure that there is sound as such. If it is not there, return to the recovery instructions.
On some phone models, the notification volume can be set separately, and some allow you to set your own ringtone for the notification. Perhaps the melody is very quiet and cannot be heard.
No sound in video
There are two reasons:
- there is no sound in the device you are using;
- The video was originally recorded without sound;
- The player or codec is not working correctly.
In the first case, you need to carry out diagnostics, but in the second, nothing can be done, in the third, you need to reinstall the player.
The sound disappears, but after a reboot it appears
Such errors occur due to a failure in system processes. Resetting the settings or carefully flashing the phone's firmware will help

Speaker not working after repair
In this case, you should contact the service center that carried out the repair. They are required to reimburse the cost of repairs, or restore sound on the device at their own expense.
How to check the speaker
The test can damage both the speakers and the phone completely if the user does not have the necessary skills for testing.
To check, you need to find a multimeter and set it to resistance measurement .
The multimedia value is approximately 8 ohms. Hearing resistance – 30 Ohm:
- Set the interval on the multimeter values from 30 Ohm.
- Attach probes to the device contacts.
- When measuring, error of several units - normal indicator. This is what the impedance of a working auditory speaker looks like.
- Check the multimedia in the same way .
Replacing the cable and speaker
Purchase
In order to disassemble the phone you need a special tool, a little skill and, in fact, the spare parts themselves - a cable and a speaker. We decided to order them from the popular online store Mobiround.ru. The delivery was fast, and a small and pleasant surprise awaited us in the parcel:
The parts are packed well and tightly:
All the fun cost 339 rubles (+delivery).
It is worth noting that in specialized stores in our city, only one train cost ~600 rubles
Phone analysis
Our photos are of poor quality and not very informative. Two excellent disassembly instructions with detailed pictures can be found here and here
First, unscrew the two Pentalobe screws with a diameter of 3.9 mm (“stars”) near the charging connector:
Next, disconnect the housing from the display. It is better to use a suction cup for this. Please note that you need to disconnect the screen at the bottom of the case: at the top there is a cable for the speaker and camera and it is very easy to break. In turn, act extremely carefully in the lower part so as not to break the TOUCH ID cable (you must remove the retainer of this cable and carefully disconnect:
We open the phone. We see our speaker and cable - they are located on the display module. Do not bend the display module more than 90 degrees:
Before you begin to release the cable and speaker, you must disconnect the battery from the system board. In principle, it needs to be turned off for any type of repair work - it’s worth remembering. To do this, we will unscrew the protective plate (two 1.6 mm Phillips screws) and disconnect the cable:
Next, we disconnect the plate that holds the upper cable and disconnect the front camera cable with the proximity sensor, the LCD screen cable and the touch screen cable from the body. Only 4 screws:
- red 1.7mm Phillips screw
- red Phillips screw 1.2 mm
- yellow 1.3mm Phillips screw
- green 1.7mm Phillips screw
Be sure to remember which one was screwed in where. If you mix up the seats during reassembly, you may damage the board.
Then you need to remove the protective plate from the top ear speaker (two Phillips screws 4.1mm and 2.2mm):
Finally, carefully remove the speaker. It does not have any connectors, and works by simply pressing it against the panel using a plate:
... and all other components that are on the same cable:
This completes the dismantling of the speaker and cable:

Audio codec or amplifier is faulty
A chip called an audio codec (U21) is responsible for the sound during a conversation on the iPhone. If you buy it, it will be designated as “large” in stores. Costs no more than 100 rubles - replacement will cost much more
The amplifier, also known as the sound controller (U22), forms the signal lines to the speakers. It must be checked for power and short circuit:
Very often during local repairs they get caught, torn off, damaged or overheated. In this case, it is necessary to replace it or reball (as professionals also say, “rolling”) the chip. It involves removing the old, existing solder balls from the chip and the board itself on which the chip is to be soldered, then cleaning the contacts (nickels) and applying new balls.
The contact between the modem and the audio codec is faulty
Quite a rare problem, but also relevant to our scenario. It is usually diagnosed by pressing (press firmly) the upper right corner, where the modem is located - the sound from it begins to reach the audio codec. The BB_I2S_RXD (i2s1) bus is responsible for this signal. It is necessary to check and, if necessary, restore tracks bb_i2s_clk, bb_i2s_rxd, bb_i2s_txd, bb_i2s_ws (chain from the modem to the central processor)
Damage to the capacitor and/or filter
This usually happens, again, due to low-quality repairs - you yourself are unlikely to be able to break the capacitor (FL49) or “tear down” the filter (C215). This is easy to do - with the usual disconnection of the coaxial wires inside the phone, it is very easy to damage them (they are located nearby)
Here is the FL49 filter in another diagram (from the video below)
On the phone itself it looks like this. The photo shows that there are not enough components on the board:
In order for the sound to appear again, it is necessary to restore these elements - tin these places with solder and install these components from another board.
