The problem of overly loud speaker on Xiaomi and Redmi smartphones is quite common, especially in new models with the shell of MIUI or HyperOS. Users complain that during a conversation, the voice of the interlocutor sounds too loud, distorts or causes discomfort, causing the phone to move away from the ear. This is not just an inconvenience, but also a potential risk to hearing when using the device for prolonged use in noisy places where you instinctively want to add sound.
Fortunately, Android provides multiple levels of audio stream control that allow you to fine-tune the sound specifically for the “in-talk” mode. Unlike the general volume of multimedia, the parameters of the conversational speaker are often hidden in additional menus or depend on the settings of codecs. In this article, we will discuss all the current methods, from simple switches in the interface to advanced settings through the engineering menu.
It is worth noting that the methods may vary depending on the version of the operating system and the specific processor (Snapdragon or MediaTek).It is important to understand that some settings require caution, as they affect the system parameters of voice transmission. We will look at safe algorithms of actions that will help you make communication comfortable without risking damage to the software of the smartphone.
Basic sound settings during the call
The most obvious, but often ignored, way is to adjust the volume directly at the time of a conversation. Many users forget that the volume buttons on a Xiaomi smartphone have contextual control. If you press them on your desktop, media or ringtone is regulated, but during an active call, they control the volume of the interlocutor.
To lower the sound, wait for the caller to connect and press the volume button on the side of the case. A slider with the tube icon will appear on the screen, and make sure that you adjust this parametre, not the overall volume of the system. Sometimes the system may “forget” the volume level for a particular contact or SIM-This is a card, so it is worth repeating the procedure for each important number.
⚠️ Attention: If the volume slider is missing during a conversation or doesn't respond to taps, Absolute Volume mode may be activated in Bluetooth settings, even if the headset isn't connected.
You also need to check the audio settings in the Phone app itself. Some versions of the MIUI contain a Smart Volume feature, or noise cancellation, which can automatically raise the sound level if the algorithm decides it's noisy, and disabling these features can solve the problem of compulsive volume up.
📊 How often do you have too loud a sound on your phone?
Constantly.
Sometimes.
Only with certain contacts.
Never, it's okay.
The most efficient way to control volume is to log into the engineering menu, which is a hidden part of the system that is designed to test equipment, but is accessible to users, and you can change the levels of sound gain for different modes of operation, including Headset and Handset.
To enter the menu, you need to open the Phone app and type a special code. For most Xiaomi devices with MediaTek processors, the code ##3646633## is used. For devices based on Snapdragon, the code may differ or be blocked by the manufacturer, in which case you will need to install a special shortcut application from the Google Play store, for example, “Engineering Mode”.
Once you log in, you'll be able to navigate through tabs, and you'll need to go to Hardware Testing, then you'll need to select Audio, then Audio Debugging. In this section, you'll see a Scenario script list, and we're interested in Normal Mode or Handset Mode, which is the speaker.
Within the selected mode, find Gain or Volume, which are usually represented as levels 0 through 6 or in digital terms (e.g. 130, 140), lowering this value will reduce the maximum volume. It is critical to keep the values below 100-110, otherwise the interlocutor will not be heard at all.
| Parameter | Description | Recommended value |
|---|
| Level 0 | Minimum volume | 80-100 |
| Level 4 | Average volume | 110-120 |
| Level 6 | Maximum volume | 130-145 |
| Digital Gain | Digital Strengthening | Don't change. |
After making changes, be sure to press the Set button to save settings. Rebooting the device is not always necessary, but desirable for all system audio profiles. If the sound is completely lost after the changes, return the values to the original position using previously recorded recordings.
What to do if the engineering menu code doesn’t work?
If the standard code doesn't open the menu, try alternative combinations: ##4636## or ##6484 "MTK Engineering's from Play Market, which enforces the right menu on MediaTek chips. Snapdragon is often blocked by the carrier. Equalizer and sound effects settings MIUI It has built-in audio tools that are often underestimated. Although they are primarily multimedia-oriented, some settings can affect the overall Perception of voice volume. → Sound and vibration → Sound effects. You should pay attention to the presets that are included. If you choose Bright or Saturated, it can add frequencies that make the voice sharp and subjectively louder. Switching to Original or Standard mode often softens the sound. Also check Dolby Atmos if your smartphone supports this technology. In some cases, manual frequency adjustment helps. The person's voice is in the midrange. If you lower the sliders slightly in the 1kHz to 3kHz area, the voice will become softer and the desire to turn down the overall volume will disappear. However, this method requires a personalized approach and checking in real conversations. If the system settings are not enough, the Google Play app comes to the aid to control the volume separately. Programs like Precise Volume or Volume Control, these allow you to create additional control standards. You can create a Conversation profile where the volume limit of the phone is limited, like 70% of the maximum, even if you twist the slider to the end, and this prevents accidental stunning when the speaker or system dramatically increases the sound level. 📱 Precise Volume: Allows you to adjust 100 volume levels instead of the standard 15, which gives you a smoother adjustment. 🔊 Volume Control: Has a widget for quick switching between Home, Office, Conversation profiles». ⚙️ Lesser AudioSwitch: Allows you to force the audio output to switch if the system mistakenly directs the voice to the speakerphone. ADB Without these rights, they can't take control of Android audio. The rights instructions are usually in the app description. Often the problem lies not in the smartphone itself, but in the connected accessories. Bluetooth headsets and headphones have their own sound amplification system. If the headset is too loud, it is the phone that you need to adjust, not the phone. In Bluetooth settings, there is an option called "Absolute Volume." If it's on, the headphone and phone volume sliders sync. Disabling this option (via the developer menu) allows you to adjust the volume of the headset separately from the phone, which often solves the problem of excessive signal level. ⚠️ Attention: When using cheap Bluetooth adapters in the car, the sound can be distorted due to the low quality of the codec. In such cases, lowering the volume on the phone will not help - you need to change the settings of the car's head unit. Some thick protective cases can overlap the bottom microphone (which is often used for noise reduction).If the microphone is closed, the system automatically compensates by amplifying the speaker, thinking you are in a noisy place. 💡Turning off the Absolute Volume feature in the developer menu is the most effective way to unwind the volume control of the phone and Bluetooth headset. Diagnostics of hardware problems dynamics If software methods do not help, it may be the hardware. The speaker may wheez or sound unnaturally loud due to dust and pile contamination of the speaker's mesh. This changes the acoustics and makes the sound resonate. Carefully inspect the top end of the smartphone. Use a soft brush or sticky tape to clean the mesh. Don't use sharp objects or alcohol, as you can damage the speaker membrane or wash off the protective coating. Another reason may be a swollen battery. In some Xiaomi models, when the battery is bloated, it starts to press on the insides of the case, including the speaker module, which changes its characteristics. If you notice that the back cover has moved away or the screen has gone "wave", immediately contact the service. Frequently Asked Questions (FAQ) Why did the sound become louder after the MIUI update? Firmware updates often reset user audio settings, which change the loudness of the device as a newer, can be changed to the newer version permanently. Android does not allow you to set the volume ceiling, but you will need third-party applications (see the section on software) or root rights to edit system files for the sound configuration. Does the region of the smartphone affect the volume of the speaker? Global (Global) and Chinese versions (CN) They can have different limits on maximum volume because of the laws of different countries, and Europe has more stringent regulations on hearing protection than Asia, so flashing can change the behavior of the speaker. What if the sound is gone after the engineering menu? You need to log back into the engineering menu and return the values_gain_ It's a factory-based (usually a Default button or manual return to the original numbers) and if you don't remember the values, you can use a full reset (Wipe Data) to remove all the data from your phone.
