The smartphone Honor 9X has deservedly received recognition from users thanks to its excellent screen and powerful processor, but its multimedia capabilities often raise questions. Device owners are often faced with a situation where the maximum standard volume is not enough to comfortably listen to music in a noisy room or watch videos on the street. This is not necessarily a defect of a particular instance; rather, it is the result of software restrictions laid down by the manufacturer to protect the audio path.
Fortunately, the architecture of the operating system Android and the shell EMUI provide fairly flexible tools for fine-tuning the sound profile. There are several proven methods to safely bypass standard limits and get the most out of your built-in speaker. In this article, we will take a detailed look at both the software settings and the hidden engineering menus available for your model.
Before moving on to radical measures, you should make sure that the problem does not lie in banal physical obstacles. Often, a decrease in sound level is due to contamination of the speaker mesh or incorrectly selected equalizer settings. We will start with basic diagnostic steps and gradually move on to more complex methods of modifying system parameters.
Basic diagnostics and physical cleaning
The first step before any software intervention should be a thorough check of the physical condition of the device. Over time, dust, clothing lint, and sebum accumulate in the speaker openings, creating a natural acoustic filter. Even a microscopic layer of dirt can reduce the volume by 20-30%, making the sound dull and quiet.
For cleaning, it is recommended to use a soft toothbrush with short bristles or a special brush for equipment. Carefully walk along the speaker grid located at the bottom end of the case, being careful not to damage the membrane with internal movements. If the contamination is serious, you can use adhesive tape (scotch tape), applying its sticky side to the mesh to draw out dust from the depths.
It is also worth checking whether there is a protective film or case glued to the bottom of the smartphone that blocks the sound output. Some accessories are poorly made and may partially block the acoustic port. Make sure that Do Not Disturb or Quiet Mode is not activated in your settings, which may programmatically limit media sounds.
⚠️ Warning: Never use sharp objects such as needles or pins to clean the speaker. You can pierce the protective mesh and damage the membrane, which will lead to irreversible deterioration in sound quality or the appearance of wheezing.
Setting the equalizer and sound effects
The built-in tools of the system EMUI offer powerful tools for correcting the sound signal. Correctly setting the equalizer allows you not only to improve the timbre, but also to visually increase the volume level by enhancing certain frequencies. To access these settings, you need to go to menu Settings → Sound and vibration → Sound effects.
Here you will find a graphic equalizer with several sliders. Try raising all the sliders to the maximum value, or selecting the Rock or Pop preset profile, which usually have a more aggressive gain curve. However, be careful: excessively raising the low frequencies can cause distortion and rattling of the case.
The function Histendeserves special attention, developed by Huawei specialists. This spatial audio algorithm can significantly improve the audio experience. Experiment with Auto, 3D, and Normal modes. In some scenarios, the Normal mode produces clearer and louder sound since it does not waste CPU resources on space virtualization.
- 🎚️ Try manually raising all equalizer bands 2-3 dB above the standard level.
- 🎧 Turn off the Absolute Volume feature in Bluetooth settings if you are using wireless headphones, this often solves the problem of quiet sound.
- 📢 Activate the "Mono Audio" option in Accessibility if one of the stereo channels is quieter than the other.
If the sound becomes hoarse after adjusting the equalizer, reset the sound settings to factory settings in the same menu and try reducing the bass boost (sliders on the left).
Using the engineering menu for calibration
The most effective way to increase the volume at the system level is to use the engineering menu. This is a hidden section of the system intended for service engineers, which allows you to directly control the parameters of the audio path. On Honor 9X access to it is through the standard “Phone” application.
To enter the menu you must enter a special code. Enter the combination ##2846579##on the dialing keypad. After entering the last digit, the menu should open automatically. If the code does not work, it is possible that your telecom operator or a specific firmware version has blocked this access.
In the menu that opens, follow the path ProjectMenu → Audio → Normal Mode. Here you will see a list of profiles, such as Media (media), Ring (call) and Mic (microphone). Select a profile Mediaas it is responsible for the volume of video and music. You will see the level (gain) values in numbers.
| Volume level | Standard value | Recommended value | Risk of distortion |
|---|---|---|---|
| Level 0 (Min) | 100 | 120 | Low |
| Level 1 | 130 | 150 | Low |
| Level 2 | 160 | 180 | Medium |
| Level 3 | 190 | 210 | High |
| Level 4 (Max) | 220 | 240 | Critical |
Change values gradually, adding 10-15 units to the current parameter. After each change, press the button Set to save. You should not immediately set the maximum values, as this can lead to overloading the speaker and the appearance of an unpleasant crackling noise at high volumes.
What to do if the code does not work?
If the code ##2846579## does not open the menu, try the code ##3646633##. Also, access may be denied on global versions of the firmware, in which case you will need to obtain root access or use third-party applications.
⚠️ Attention: Making changes to the engineering menu may lead to unstable operation of the audio system. Write down the original values before changing so that you can return everything as it was in case of wheezing or loss of sound.
Third-party applications for sound amplification
If fiddling with engineering settings seems too complicated or risky, specialized applications from the store will come to the rescue. Google Play. These apps work as software amplifiers, amplifying the digital signal before sending it to the DAC (digital-to-analog converter).
One of the most popular solutions is the application Volume Booster GOODEV. It features a simple interface and an automatic gain function. Once installed, simply launch the application, check the Enable box and adjust the gain slider. It is recommended not to exceed the 20-30% mark to avoid digital distortion.
Another powerful tool is Equalizer & Bass Booster. This application not only increases the overall volume, but also allows you to fine-tune the frequency range. You can boost only those frequencies that are lost on your speaker while maintaining the purity of the rest of the spectrum. The application supports most popular music players.
- 📱 Make sure that the application has permission to change system sound settings.
- 🔋 Remember that constantly running an amplifier in the background may slightly increase battery consumption.
- ⚠️ Avoid applications with a rating below 4.0, as they may contain advertising or malicious code.
It is important to understand that third-party applications cannot physically make the speaker more powerful. They only increase the level of the input signal. If the speaker is already operating at the limit of its mechanical capabilities, additional software boost will only lead to wheezing and distortion.
Third-party boosters are effective when the standard volume is limited by software, but are useless if the speaker is physically weak or clogged with dust.
Modifying system files (for advanced)
Users with superuser rights (Root) have the ability to edit system configuration files. This method is the most radical and allows you to remove all software restrictions imposed by the manufacturer on the audio path.
The main file responsible for audio mixing is usually located along the path /system/etc/mixer_paths.xml or /vendor/etc/mixer_paths.xml. To edit, you will need a file manager with Root support, for example Root Explorer or MT Manager. In this file you need to find tags responsible for speaker amplification (often contain the words speaker, gain, amp).
<path name="speaker"><ctl name="RX7 Digital Volume" value="84"/>
<ctl name="COMP7 Switch" value="1"/>
</path>
Changing parameter values value, you can increase the gain. However, the structure of these files highly depends on the specific audio chip installed in Honor 9X. An error in one character can cause the sound to disappear completely or the smartphone to stop loading.
☑️ Preparing to edit system files
⚠️ Attention: Editing system files without proper experience can turn your smartphone into a “brick”. Be sure to create a full backup of the system via Recovery before making any changes.
Eliminating software conflicts and resetting settings
Sometimes the problem of quiet sound lies not in a lack of power, but in a software conflict. Third-party applications, especially those that control audio or have access to audio services, can take over control and lower the volume. Try starting your smartphone in safe mode.
To enter safe mode, hold down the power button, and then long-press the “Turn off” option on the screen until you are prompted to reboot into safe mode. If the volume becomes normal in this mode, then one of the applications you installed is to blame. Delete them one by one to find the culprit.
As a last resort, if all else fails, you can reset your phone to factory settings. This will delete all user data and return the system audio settings to their original state, eliminating any accumulated software errors. Before doing this, be sure to save important data.
Go to Settings → System → Reset → Reset phone settings. The process will take a few minutes, after which the smartphone will reboot. Check the volume immediately after turning on, without installing third-party applications, to evaluate the purity of the sound.
Frequently asked questions (FAQ)
Why did the sound become quieter after updating the firmware?
Manufacturers often release updates that change audio algorithms to protect the speaker from overload or to comply with new safety standards. Also, the update could reset your personal equalizer settings.
Is it possible to increase the call volume separately from the media?
Yes, in the engineering menu (##2846579##) there are separate profiles for Ring (call) and Media (media). You can increase the gain only for the call profile, leaving the media at the standard level.
Is constant use of maximum volume harmful for the speaker?
Yes, prolonged operation at maximum volume, especially with the use of boosters, leads to overheating of the speaker coil and stretching of the suspension. This shortens the life of the component and can cause wheezing.
Will replacing the speaker with a more powerful one help?
Physical replacement is possible, but extremely difficult due to the unique shape and mounting of the speaker in Honor 9X. Third-party analogues may not be suitable in size or impedance, which will lead to quiet sound or damage to the audio chip.
Why is there sound only in the headphones, but the speaker is silent?
This may indicate a hardware failure of the speaker, oxidation of the cable contacts, or a software failure in which the system “thinks” that the headphones are connected. Try cleaning the headphone jack or resetting the settings.
