Have you turned on video, music, or are trying to answer a call, but there is no sound coming from the phone speaker? This problem is familiar to many owners of Androidsmartphones - from budget Xiaomi Redmi to flagship ones. The reasons can be either software (failure in settings, update error) or hardware (damage to the speaker or connector). In 80% of cases, the sound can be restored independently - without contacting a service center. Samsung Galaxy S23. The reasons can be either software (failure in settings, update error) or hardware (damage to the speaker or connector). In 80% of cases, the sound can be restored independently - without contacting a service center.

In this article we will examine all possible reasons for the disappearance of sound the dynamics, from the banal (accidentally turned on silent mode) to complex (damage to the audio codec). You will receive step-by-step guide with illustrations, a table of compatibility of solutions for different brands, as well as answers to frequently asked questions. If the problem is not a physical breakdown, you will get the sound back in 5-10 minutes.

Before starting diagnostics, check the obvious: whether headphones or column. Sometimes the sound “goes” to an external device, and the user does not notice it. Also make sure that Bluetooth- headphones or speaker. Sometimes the sound “goes” to an external device, and the user does not notice it. Also make sure that Volume is not set to minimum —on some models (for example, OnePlus) the volume control is divided into media and calls.

1. Checking basic settings: what could turn off the sound?

Start with basic checks - often the sound disappears due to accidental clicks or firmware failures. Here's what you need to do first:

  • 🔊 Check the physical audio switch (if your model has it). Some smartphones (for example, iPhone-like Meizu or Oppo Find X) have a hardware toggle switch that puts the phone into silent mode. Even if you Android, inspect the case for mechanical buttons.
  • 📱 Make sure that Do Not Disturb mode is not activated. Go to Settings → Sound and vibration → Do not disturb and disable it. On some firmware (for example MIUI or ColorOS) this mode can block all sounds, including media.
  • 🔄 Reboot your phone. A simple but effective method: hold down the power button for 10–15 seconds until the device turns off, then turn it on again. This will clear temporary errors in the audio drivers.
  • 🎧 Disable all Bluetooth devices. Sometimes the sound “sticks” on previously connected headphones or speakers. Go to Settings → Connected devices and turn off everything.

If after these manipulations the sound does not appear, proceed to the next step. Pay special attention to items with Bluetooth and Do Not Disturb mode - they are responsible for 30% of cases of sound loss.

  3. Reset to factory settings after flashing the firmware.
What to do if the firmware is damaged during the update?

If the phone stops turning on after an unsuccessful update (“brick”), try entering the mode Recovery (hold Power + Volume up when turning on) and run Wipe Data/Factory Reset. If this does not help, you will need to flash it via a PC using the manufacturer's official utilities.

Attention! Rolling back the firmware may lead to loss data. If there is important information on the phone, try other methods first or create a backup copy via ADB (instructions below).

4. Hardware faults: how to check the speaker and connectors

If the software methods did not help, there may be a problem. in physical breakdown speaker, audio chip or connector. Here's how to diagnose it:

Speaker test for mechanical damage

  • 🔍 Shine a flashlight into the speaker grille - if dust, dirt or moisture is visible, this could cause corrosion of the membrane.
  • 🎵 Turn on the music at maximum volume and bring your ear to the speaker. If distortion is heard, there is a crackling sound, or there is sound, but it is very quiet, the speaker is damaged.
  • 🛠️ Gently press the housing around the speaker. If the sound appears or changes, the problem is in poor contact (the cable comes off or the contacts have oxidized).

Checking the 3.5 mm jack (if any)

If you are using wired headphones, inspect the connector on the phone:

  • 🎧 Plug in the headphones and wiggle them slightly plug If the sound appears and then disappears, the connector is loose or oxidized.
  • 🔌 Check whether there is any debris or plug fragments left in the connector (a common problem after using cheap headphones).

Diagnostics of the audio codec

Audio codec (chip, responsible for audio processing) may fail after the phone is dropped or gets wet. Signs of its breakdown:

  • The sound disappears completely, including calls and notifications.
  • The phone does not recognize the connected headphones or speakers.
  • There are no volume control options. Settings → Sound There are no volume control options.

If you suspect a breakdown of the audio codec, Independent repair is not possible the chip needs to be replaced at a service center. Average cost of repair: from 1,500 to 5,000 rubles, depending on the model.

💡

If the phone has been dropped or gotten wet, do not turn it on immediately - let it dry for 24–48 hours in a dry place (for example, in rice or silica gel). Trying to turn on a device with moisture inside may cause a short circuit and damage the motherboard.

5. Restoring sound via ADB (for advanced users)

If the sound disappeared after installing custom firmware or rooting, this will help ADB (Android Debug Bridge). This method requires connecting your phone to a PC and basic knowledge of the command line.

Step 1: Installing ADB

Download Platform Tools from the official website Google (developer.android.com) and unzip the archive. Enable on your phone USB debugging v Settings → About phone → Build number (press 7 times to unlock developer mode).

Step 2: Commands to reset the sound

adb shell

su


settings put global volume_music 15


settings put global volume_alarm 15


settings put global volume_notification 15


settings put global volume_system 15


settings put global volume_voice 15


reboot

These commands will reset the volume levels for all channels. If after reboot the sound does not appear, try resetting the settings Audio Policy:

adb shell

su


rm /data/vendor/audio/*


reboot

Attention! Commands with su require rootrights. If they are not available, skip this line. Incorrect use of ADB may cause the system to crash.

6. can we get by?

If none of the above methods help, the problem is most likely hardware. Here are the signs for which you should contact the service:

Symptom Possible cause Repair cost (approximately)
The sound disappears when you press the case The speaker cable comes off 800–2 000 ₽
There is sound only in the headphones The audio codec or speaker is damaged 1 500–5 000 ₽
The phone does not recognize headphones The 3.5 mm or USB-C connector is faulty 1 000–3 000 ₽
The sound is distorted, with wheezing The speaker membrane is damaged 1 200–2 500 ₽
No sound and the microphone does not work Damaged motherboard 3 000–10 000 ₽

Before visiting the service:

  • 📋 Write down the phone model and serial number (located on the box or under the battery).
  • 💰 Check the cost of diagnostics - in some centers it is paid (300-500 ₽).
  • 🔧 If the phone is under warranty, do not open it yourself - this will void the warranty.

How to choose a service center?

Give preference to the manufacturer’s official services or trusted workshops with reviews. Avoid “garage” repairs - a cheap replacement of the speaker can result in problems with the microphone or buttons.

💡

If the phone got wet, tell the technician about it - moisture could damage several components, and diagnostics “by eye” will be incomplete.

FAQ: Frequently asked questions about missing sound in Android

🔊 Why is there sound in the headphones, but not in the speakers?
