How to really increase the volume of the speaker on Xiaomi Redmi Note 7: from settings to firmware

The hearing speaker on the Xiaomi Redmi Note 7 is often criticized for low volume during calls or media playback. Even at maximum settings, the sound can be quiet in noisy rooms or when using hands-free. The problem is not always with the hardware - most often the volume is limited by software to protect the speaker from overload.

In this article, we will look at all the working ways to increase volume, from standard MIUI settings to deep changes in system files. It is important to understand that some methods require superuser rights (root) or can lead to a loss of warranty if you do not act correctly, we will specify the risks for each option and provide recommendations for security.

If you're not ready to experiment with firmware, start with the first three ways -- they're knowledge-free and reversible. For advanced users, we've prepared instructions for engineer mode, file modifications. mixer_paths.xml and custom-nucleation.

1. Standard MIUI settings: what can be squeezed without risks

Before you get into system files, check the basics. the Xiaomi Redmi Note 7 based on MIUI 10-14 has hidden audio amplification options that many users miss.

The first thing to do is to activate the "Amprovement of sound" mode in the settings of special features:

1. Open the Settings. → Special facilities.
2. Go to the Rumor section.
3. Turn on the option of amplification of sound and set the slider to the maximum value.

This mode only increases the volume for media files, but does not affect calls.

For calls, check the individual settings:

• 📞 Loud communication during the call: in Settings → Sound and vibration → Enable the option to amplify the sound.
• 🔊 Equator: In Settings → Sound and vibration → Sound quality choose Bass preset or Rock – this indirectly increases the overall volume.
• 🚫 Volume Limitation: C Settings → Annexes → Permits → Autorun: Turn off restrictions for audio-related applications (e.g. Mi Sound Enhancer).

⚠️ Warning: If the sound becomes hoarse or distorted after amplification is turned on, return the default settings. This is a sign that the speaker is working at the limit of its hardware capabilities.

2. Engineering menu: hidden options for advanced

The Redmi Note 7 has a hidden engineering menu (Engineer Mode) where you can manually adjust the speaker settings. This method does not require root rights, but is informally supported by Xiaomi - use it at your own risk.

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##36446337## (code may not work on some firmware).
3. If the code doesn’t work, try ##4636##, then go to the Hardware Testing → Audio tab.

In the Audio menu, you are interested in the following options:

• 🔧 Type: Select LoudSpeaker Mode (for the main speaker) or Headset Mode (for headphones).
• 📊 Value: you can increase the values of Max Vol (maximum volume) and Min Vol (minimum — 160, can be raised to 180-200 (higher!).
• 🔄 Set: After changing the values, click Set, then Save.

⚠️ Note: Exceeding the value of Max Vol = 200 It can cause physical damage to the speaker. 10-20 Test the sound for distortions and.

3. Apps to amplify sound: top-5 utilities

If you don't want to go through the settings, you can use third-party apps, and we've tested dozens of utilities and selected those that actually work on the Redmi Note 7 without root:

The most balanced version is the Volume Booster GOODEV, which allows you to increase the volume by 20-30% without noticeable distortion.

1. Download the app from the Play Market.
2. Start and give all necessary permissions.
3. Move the Media Volume slider 80-90% (maximum can cause wheezing).
4. Activate the Boost Speaker option.

⚠️ Attention: Apps like ViPER4Android require additional drivers, which can lead to bootloop ( looped boot) on some versions MIUI. Before installation, make a backup copy!

4. Modifications mixer_paths.xml: manual editing

This method requires root rights and is designed for power users. mixer_paths.xml It contains volume limits for all audio devices on your smartphone, and editing it allows you to remove software limits, but if you make a mistake, you run the risk of being without sound at all.

Instructions for modification:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Cross the path: /system/vendor/etc/mixer_paths.xml (or mixer_paths_tasha.xml firmware).
3. Make a copy of the file on an external drive.
4. Open the original in a text editor (e.g. QuickEdit).
5. Find the following lines: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Change the value from 84 to 90-95 (no higher!).
6. Save the file and restart the device.

If the sound is gone or robotic after editing, return the original file. Also check for microphone lines (mic) - changing them can worsen the quality of communication.

💡

Before editing mixer_paths.xml Check if it's in the folder. /vendor/etc file mixer_paths_override.xml. If he is, he must rule, he has priority over the main.

5.Castom firmware and cores: maximum amplification

If standard methods fail, you can still install custom firmware or kernel, which is the riskiest way, but also the most effective way, with some firmware (like Pixel Experience or LineageOS) having optimized audio drivers.

For Redmi Note 7 (codename lavender) the following solutions are suitable:

• 📱 Projekt Treble: firmware based GSI (Generic System Image with improved audio system.
• 🔧 KernelSU + Magisk: Modules like Audio Modification Library allow you to fine-tune the sound.
• 🎵 ViPER4Android + JamesDSP: The combination of these modules gives equalizer and amplification control.

The process of installing custom firmware:

1. Unlock the bootloader through Mi Unlock Tool (Xiaomi account binding is mandatory!).
2. Install custom Recovery (TWRP or OrangeFox).
3. Download the firmware for lavender from the XDA Developers or 4PDA forum.
4. Wash through the Recovery, pre-wipe Dalvik/Cache, System, Data.

⚠️ Attention: Installing custom firmware voids warranty and can lead to a brick (completely inoperable) device. Redmi Note 7 also known problems with the proximity sensor after firmware - the sound during the call can turn off when you bring the phone to the ear.

💡

Custom firmware gives a volume increase of up to 40%, but requires a deep knowledge of Android firmware. Beginners are better off focusing on apps or engineering menus.

Hardware solutions: when software methods do not help

If none of the above methods worked, the problem could be physical wear and tear on the speaker or poor contact.

First, check the speaker for dust or mechanical damage:

• 🔍 Examine the speaker grille for dirt, clean it with a soft brush or compressed air.
• 🎧 Connect headphones – if the sound in them is loud, the problem is precisely in the dynamics.
• 🔊 Check the sound in safe mode (press the power button). → Safe Mode. If the sound gets better, it's the third-party app's fault.

If the speaker is damaged, it can be replaced by yourself:

1. Buy the original speaker for the Redmi Note 7 (article: XIAOMI 18051HY541010).
2. Remove the back cover with a mediator and a hair dryer (the sticky base needs to be warmed up!).
3. Disconnect the speaker plume and replace it with a new one.
4. Check the contacts on the board – often oxidation causes a quiet sound.

Cost of replacement at the service center: ~1 500–2 500 ₽ (spare-part).

7. Alternative solutions: if nothing has worked

If all attempts to increase the volume have failed, consider alternative options:

• 📴 Use a Bluetooth speaker or headphones: even budget models like Xiaomi Mi Portable Bluetooth Speaker will give a cleaner and louder sound.
• 🔄 Activate the "In the car" mode: in Settings → Sound. → Select In the car – this will increase the volume of the microphone and speaker during calls.
• 📱 You can use the phone to the stock. MIUI: Sometimes custom firmware or "curve" updates optimize the sound. MIUI 12.5 Enhanced is considered one of the most balanced for the Redmi Note 7.
• 🔧 Reverse to an older version MIUI: Some users note that the sound became quieter after updating to the MIUI 13/14. Try to sew it. MIUI 11 via Mi Flash Tool.

If you make frequent calls in noisy places, consider buying an external microphone with a speaker (like Xiaomi Bluetooth Neckband).It connects over Bluetooth and provides hands-free communication without loading on the built-in speaker.
