You turned on video or music on your smartphone, but instead of smooth sound you hear unpleasant increasing volume - first quietly, then louder, then quieter again? This problem is familiar to many owners of devices on Android, especially after system updates or installation of third-party applications. Most often, settings Dolby Atmos, Adaptive Sound or system bugs are to blame, but sometimes the cause is hardware malfunctions.

In this article we will analyze all possible reasons increasing sound - from software failures to firmware features. Samsung One UI, Xiaomi MIUI i Huawei EMUI. You'll learn how to diagnose the problem, which settings to check first, and what to do if standard methods don't help. For convenience, we have collected 7 working methodsincluding solutions without root access and using the engineering menu.

Important: if an increasing sound appeared after the phone was dropped or moisture got in, the problem may be due to damage to the speaker or audio chip. In this case, it is better to contact the service center.

1. Checking the sound and effects settings

The first thing to do is disable all sound effects, which can automatically adjust the volume. On different firmware, these settings are called differently, but the essence is the same: adaptive algorithms sometimes malfunction.

On most devices, the path looks like this:

  • 🔊 Dolby Atmos / Dolby Digital: Settings → Sound → Sound quality and effects → Dolby Atmos (disable or select the "Off" mode)
  • 🎵 Adaptive Sound (Samsung): Settings → Sound and vibration → Sound quality and effects → Adaptive Sound (switch to "Off")
  • 🔄 Automatic volume control (Xiaomi/Redmi): Settings → Sound → Advanced settings → Auto volume control
  • 🎧 Effects for headphones: If the problem occurs only with headphones, check the settings in Settings → Sound → Effects for headphones

After disabling effects reboot the device —sometimes changes are applied only after a reboot. If the rising sound disappears, it means that one of the audio processing algorithms was at fault.

💡

On some devices Samsung Adaptive Sound may be hidden in the menu Settings → Device maintenance → Battery → Advanced → Adaptive battery. Do not confuse with sound settings!

2. Reset sound settings to factory settings

If disabling effects did not help, the next step is reset audio settings. This will return all audio parameters to factory settings, including uniform volume.

Instructions for most firmware:

  1. Open Settings → System → Reset settings (the path may differ on some devices).
  2. Select item Reset sound settings or Reset all settings (do not confuse with a full factory reset!).
  3. Confirm the action. The device will reboot.

On firmware MIUI (Xiaomi/Redmi/Poco) the path is different:

Settings → About phone → Advanced → Reset settings → Reset sound settings

Disconnect Bluetooth headphones

Close all audio applications (YouTube, Spotify, etc.)

Check the battery level (minimum 30%)

Make a backup copy of user equalizers (if using)

-->

After After reset, test the sound in different applications: YouTube, Google Podcasts, standard player. If the volume increase disappears, the problem was a settings conflict.

3. Firmware update or rollback

Increasing sound often appears after Android updates or firmware from the manufacturer. For example, users Samsung Galaxy S22 complained about this problem after updating to One UI 5.1, and owners Xiaomi Redmi Note 10 - after switching to MIUI 14.

Solutions:

  • 🔄 Check available updates: Settings → Software update → Download and install. Sometimes bugs are fixed in the following patches.
  • ⏮️ Rollback to the previous version (if the problem appeared after the update). To do this, you will need official firmware and a tool like Odin (Samsung) or Mi Flash (Xiaomi).
  • 🛠️ Manual installation of the patch: On forums (for example, 4PDA) they often post unofficial fixes for sound bugs.

Warning: rolling back the firmware can lead to data loss problems with Google Pay/Samsung Pay (due to resetting security keys). Before the procedure, make a backup copy.

Android updates

Installing a new application

Connecting headphones/speakers

Falling or hitting the phone

On its own, for no apparent reason-->

4. Checking applications and conflicts

Third-party applications, especially those that work with sound in the background, can hijacking volume control. Frequent culprits:

  • 🎵 Music players (Spotify, VLC, Poweramp)
  • 🎧 Headphone applications (Sony Headphones Connect, JBL Portable)
  • 🔊 Uniform utilities (Equalizer FX, Wavelet)
  • 🤖 Automators (Tasker, MacroDroid)

How to find the culprit:

  1. Start the phone in safe mode (press the power button → "Safe Mode"). Only system applications work in it.
  2. Check the sound. If there is no increase, third-party software is to blame.
  3. Delete or disable sound-related applications one by one until you find the problem.

Pay special attention to applications with permissions MODIFY_AUDIO_SETTINGS i RECORD_AUDIO. They can be checked in Settings → Applications → Permissions → Microphone/Sound.

How to remove system applications without root?

To remove built-in applications (for example, Dolby Atmos on Samsung) you can use the ADB command:

adb shell pm uninstall -k --user 0 com.dolby.daxapp

The list of packages for your device can be found on thematic forums. Be careful - removing system components can lead to unstable operation!

5. problems

If software methods do not help, the reason may lie in hardware:

  • 🔈 Damaged speaker: After a fall or moisture, the speaker membrane may vibrate unevenly, creating a growing effect.
  • 🔌 Oxidized contacts: On the connector Type-C or 3.5 mm (if any) the contacts may oxidize, which leads to intermittent sound.
  • 🔋 Faulty audio chip: Less common, but found on devices after repair or overheating.

How to check:

  1. Connect other sound source (headphones, Bluetooth speaker). If the problem remains, the software or audio chip is to blame.
  2. Try to play the sound through Type-C (if there is support) or Bluetooth. If there is no increase, the problem is in the dynamics.
  3. Shine a flashlight into the speaker. Is there any visible damage to the membrane? This means that repairs are needed.

For accurate diagnostics, you can use the engineering menu (see the next section) or test applications like Phone Doctor Plus.

💡

If the growing sound appears only in the speakers, and through headphones everything is fine - with a 90% probability, a hardware defect in the speaker or its contacts is to blame.

6. Engineering menu and hidden settings

In the engineering menu (Engineering Mode), you can test audio paths and change parameters that are not available in standard settings. Be careful —incorrect changes can lead to unstable operation!

How to open the engineering menu:

  • 📱 On most devices: dial in the phone application ##36446337## (for Mediatek) or ##4636## (universal code).
  • 🔧 On Samsung: #0# (hardware test) or *#9900# (sysdump).
  • 🍎 On Xiaomi: ##4636## → Hardware Testing → Audio.

In the audio test menu:

  1. Select LoudSpeaker Mode (for speaker) or Headset Mode (for headphones).
  2. Test playback at different frequencies. If the increase appears only at certain frequencies, the problem is in the equalizer settings or a hardware defect.
  3. Try resetting the audio chip settings (if there is such an option).
💡

On some devices Qualcomm in the engineering menu there is an item Audio → Volumewhere you can manually configure volume curve for each type of output (speaker, headphones, Bluetooth).

7. Alternative methods (root, ADB, custom firmware)

If all else fails, radical measures remain. They require root access or an unlocked bootloader, so they are suitable only for experienced users.

Methods:

  • 🔓 Removing system sound modules via Magisk or TWRP. For example, you can deactivate Dolby or SoundAlive.
  • 📱 Installing custom firmware (for example, LineageOS or Pixel Experience). Many custom firmwares have a “clean” sound stack without proprietary effects.
  • 🖥️ Manual editing mixer_paths.xml —a file responsible for sound routing. Requires knowledge of the structure /vendor/etc.
  • 🔧 ADB commands to reset the audio policy: 
    adb shell settings put global volume_steps 15

    adb shell settings put global volume_music_steps 15

    (this will reset the number of volume steps to standard values).

Warning: incorrect actions with root access may disable the device or cause security problems (for example, it will stop working Google Pay). Before experiments, make a full backup by TWRP.

How to make a backup of sound settings before editing system files?

Use Root Explorer or FX File Explorer with root access to copy folder /vendor/etc to an SD card or to the cloud. The following files are especially important:

  • mixer_paths.xml
  • audio_effects.conf
  • sound_trigger_mixer.txt

Comparison of methods for eliminating rising sound

As can be seen from the table, the most secure and effective methods —resetting sound settings and deleting conflicting applications. Methods with root access give maximum control, but are only suitable for experienced users.

Frequently asked questions

🔊 Why does the increasing sound appear only in headphones?

Most likely there is a problem in equalizer settings for headphones or in the accessory itself. Try:

  1. Disable all headphone sound effects in settings.
  2. Test the headphones on another device.
  3. Clean the connector 3.5 mm or Type-C from dust (use a wooden toothpick soaked in alcohol).

If the headphones are Bluetooth, try resetting their settings or updating the firmware (if available).

📱 Can a virus cause an increasing sound?

Theoretically yes, but unlikely. Viruses usually do not interfere with low-level audio settings, since this requires deep resolutions. However, some adver tasks (advertising viruses) can intercept media control, which leads to volume jumps.

Check the device using Malwarebytes or Dr.Web Light. Pay attention to applications with suspicious permissions (for example, access to MODIFY_AUDIO_SETTINGS for no obvious reason).

🔄 After resetting the settings, the sound became quieter. How to return the previous volume?

Resetting often returns the volume limits set by the manufacturer. To return the previous level:

  • Install the application Volume Booster (for example, Precise Volume).
  • Use the engineering menu to manually adjust the volume (item Audio → Volume).
  • On devices with root access, edit the file mixer_paths.xml, by increasing the values max_volume for the speaker.

⚠️ Attention: excessive increase in volume can lead to damage to the speakers!

🛠️ The service center says that it needs to be replaced audio chip. Is this so?

If all software methods have been tried, and the increasing sound remains, yes, the problem may be in audio chip (for example, Qualcomm WCD93xx or Cirrus LogicHowever, before replacing the chip:

  • Make sure that the problem occurs on all outputs (speaker, headphones, Bluetooth).
  • Test the device on a different firmware (for example, custom).
  • Seek a second opinion - sometimes the chip is changed in vain, and the problem lies in the firmware or contacts.

The cost of replacing an audio chip varies from 3,000 to 15,000 rubles depending on the smartphone model.

🔧 Is it possible to roll back only the sound driver without touching the entire firmware?

On most devices no, since sound drivers are built into boot.img or vendor. However, there are workarounds:

  1. Install a custom kernel (for example, FrancoKernel), which may contain updated sound drivers.
  2. Use Magisk-modules like ViPER4Android or JamesDSP, which replace sound processing at the system level.
  3. On some devices (for example, Google Pixelyou can manually flash vendor.img from the old firmware, but this is risky.

If none of the methods helped, we recommend contacting the service center with a detailed description of the steps taken. Perhaps your smartphone model has unique bugwhich is not yet known to the general public.

💡

Before visiting the service center save audio system logs using the application MatLog (filter by keyword "audio"). This will help specialists diagnose the problem faster.
