The Xiaomi Redmi Note 5 hearing aid (codenamed Whyred) is often criticized for quiet sound while calling or playing media through the top speaker, a problem particularly noticeable in noisy rooms or when using the device as a hands-free speaker. The reasons may be covered by software constraints. MIUI, and in the hardware features of the model - the speaker here has modest characteristics: resistance 8 Ohms and power 0.5 W.
In this article, we will look at all the working methods of increasing volume, from safe system settings to risky firmware modifications and hardware improvements. It is important to understand that some methods can lead to distortion of the sound, overheating of the speaker or even failure, so we will describe in detail the pros, cons and consequences of each approach, as well as give checklists for safe operation.
If you're not willing to risk a warranty or a device's performance, start with the first three methods -- they don't require root rights and are reversible. For advanced users, we'll give you instructions on how to work with engineer mode, modifications. mixer_paths.xml and even replacing the speaker with a more powerful analogue.
1. Program settings MIUI: What to do without root
Letβs start with the safest tool β built-in tools. MIUI. The manufacturer has provided several ways to adjust the sound, which are often ignored by users.
The first thing to check is the sound modes. Go to Settings. β Sound and vibration β Sound quality. Presets are available here:
- π΅ Balanced β Standard profile with moderate bass and tops.
- π Loud β Increases the overall volume due to small distortions.
- π§ Headphones β optimized for wired accessories, but can indirectly affect the speaker.
Select Loud Mode and check the difference. If the changes aren't enough, move on to the next step.
The second tool is the call amplifier. In the same audio settings, find the audio amplification section (may be called Additional settings depending on the version). MIUI). Activate the option to amplify the speaker, which will increase the volume of the speaker by 15-20% without loss of quality, but only during calls.
Third point β disabling restrictions EU-If your Redmi Note 5 is purchased in Europe, it may be artificially low due to local regulations:
- Install Activity Launcher from Google Play.
- Find the activity in it com.android.settings.Settings$SoundSettingsActivity.
- In the menu, find the hidden option Disable. EU Volume Limit and activate it.
π‘
After changing the sound mode, restart the device β this will help apply the settings correctly, especially if the sound was previously βresetβ after the call.
2. Engineering menu: hidden volume settings
The Engineering Mode allows you to manually adjust volume levels for different scenarios, a method that does not require root rights, but requires caution β incorrect values can damage the speaker.
To open the engineering menu:
- Open the Phone app.
- Enter the code ##36446337## (or #4636## β Hardware Testing β Audio).
- Select LoudSpeaker Mode (or Speaker depending on the firmware version).
On the menu you will see a few sliders:
- π Media β Multimedia volume (video, music).
- π Ring - volume of the call.
- π£οΈ Voice Call β Volume of Speaking Speaker.
- π€ Mic - Microphone Sensitivity (does not affect the speaker).
Recommended values for the Redmi Note 5:
| Parameter | Max, the safe value. | Risk of excess |
|---|---|---|
| Media | 140 | High frequency distortions |
| Ring | 130 | Crackling on long-term signal |
| Voice Call | 120 | Overheating of the speaker with long calls |
Set the values not higher than the recommended|Check the sound after each change.|Do not increase the Mic β it will not affect the speaker|Save the original values (take a picture of the screen)|Restart your phone after settings-->
β οΈ Warning: If after changing the parameters in the engineering menu, the speaker begins to wheez or make extraneous noise, immediately return the values to the standard (usually 100-110) and restart the device. Prolonged work at inflated levels can lead to rupture of the speaker membrane.
3. Apps to amplify sound: top-5 tested
If the built-in settings don't work, you can use third-party apps, and we tested 15 programs and selected those that actually work on the Redmi Note 5 without root rights.
Best options:
- π± Volume Booster GOODEV β It increases volume by 30 to 40 percent through software processing.
- π Equalizer & Bass Booster β allows you to fine-tune the equalizer and amplify low/high frequencies.
- ποΈ Precise Volume - gives access to the 150 Volume levels instead of standard 15. Demands. ADB-command to unlock full functionality: adb shell pm grant com.phasc.precisevolume android.permission.WRITE_SECURE_SETTINGS
- π Sound Amplifier (from Google) β amplifies the sound in headphones and speakers, optimized for conversations (+10β15%).
- π οΈ ViPER4Android β The most powerful tool, but requires root or Magisk. Allows you to adjust the sound at the driver level, including virtual surround and compressor.
For installation ViPER4Android You can use the Magisk module on a non-rooted device, but this will require unlocking the loader and installing a custom Recovery:
How to install ViPER4Android without root
Important: applications like Volume Booster are software-assisted, which can lead to clipping and distortion. Use pure sine wave test tracks (e.g., 1 kHz sine wave on YouTube) to check for quality.
π‘
Applications without root rights give a moderate increase in volume (+10 to 30 percent, but they don't solve the problem of weak hardware speakers.
4. Modifications mixer_paths.xml: hand-modeling
File. mixer_paths.xml It contains Android audio path settings, including volume limits, and editing it allows you to remove software limits, but requires root rights and syntax knowledge. XML.
Before the start of the work:
- Backup the original file (for example, by copying it to a PC).
- Use Root Explorer or Solid Explorer with superuser rights.
- The file is on its way: /vendor/etc/mixer_paths.xml (or /system/etc/mixer_paths.xml older MIUI).
Looking for lines with parameters:
<path name="speaker">
<ctl name="RX1 Digital Volume" value="84" />
<ctl name="RX2 Digital Volume" value="84" />
</path>Values are responsible for volume. Safe range to zoom in: 84 β 90-95 Example of a modified block:
<path name="speaker">
<ctl name="RX1 Digital Volume" value="92" />
<ctl name="RX2 Digital Volume" value="92" />
</path>You can also change the settings for calls (path name)="voice-call and multimedia (path name)="mediaβ). After saving the file:
- Change the access rights to 644 (rw-r----).
- Reset the device.
- Check the sound with a test track β if there are distortions, reduce the values.
β οΈ Attention: Incorrect editing mixer_paths.xml It can cause complete loss of sound or looping of the boot system. If the phone does not turn on after the changes, restore the original file through the system. TWRP or Fastboot.
5. Hardware modifications: replacement of the speaker and modification of the scheme
If the software methods do not work, there is hardware intervention. Redmi Note 5 is equipped with a speaker 0825 with an impedance of 8 Ohms and a power of 0.5 W. It can be replaced with a more powerful analogue, but this will require soldering and the risk of damage to the board.
Suitable replacements:
| Dynamics model | Impedance | Power | Volume up. | Complexity of installation |
|---|---|---|---|---|
| AAC 0825-8Ξ©-1W | 8 Om | 1 Watt | +40β50% | Medium (sweatering) |
| GoerTek GK3020 | 8 Om | 0.8 Watt | +30% | Lightweight (glue fastener) |
| Knowles RAB-32162 | 32 ohm | 0.3 W | +10% (best quality) | Difficult (requires a resistor) |
Replacement process:
- Unplug the back cover with a plastic shoulder blade and hair dryer (heat to 60-70)Β°C).
- Disconnect the battery plume to avoid short circuit.
- Unpold or disconnect the original speaker connector (depending on the replacement model).
- Install a new speaker by fixing it on two-way scotch or soldering contacts.
- Check the polarity of the connection β the wrong phasing will lead to the absence of bass.
The alternative is to redesign the power circuitry of the speaker. TPA6130 or LC-filter to improve the frequency, but it requires electronics skills:
Connection scheme TPA6130
Cost of replacement speaker in the service center: 1,500β3,000 β½ (Self-replacement costs 500-1,200. β½ (price-performance + tool).
6.Alternative solutions: when the speaker is not saved
If all methods have been tried and the sound is still quiet, consider alternatives:
- π§ Bluetooth headphones β even budget models (e.g. Xiaomi Mi Basic) will give better quality than the built-in speaker.
- π External speaker β portable speakers (e.g. Xiaomi Mi Portable Speaker) are connected via Bluetooth or through a 3.5mm connector.
- π± Sound forwarding β in the settings Special features can enable audio output to Bluetooth-device by default.
- π Update of the firmware - in new versions MIUI Sometimes they optimize sound profiles. Check for updates in Settings. β The phone. β Updating the system.
For users who often call in noisy places, a noise-cancelling headset (such as the Xiaomi AirDots Pro) will not only improve audibility, but also reduce the load on the built-in speaker by extending its life.
If the problem is the distortion of the sound (crackling, wheezing), it's possible that the speaker is physically damaged, and in this case, only a replacement will help.
- Play the test track with a pure tone of 1 kHz.
- If the sound is intermittent or with artifacts, the speaker is faulty.
- If the sound is clean but quiet, the problem is with the firmware settings or limitations.
7. Frequent mistakes and how to avoid them
When trying to turn up the volume, users often make critical errors that lead to failure.-5 Failures and ways to prevent them:
Error 1: Setting the maximum values in the engineering menu
Many people immediately put all sliders on 160-200, hoping for maximum effect. The result is: the speaker overheats, the membrane is deformed, irreversible distortions appear. So, increase the values gradually, in steps of 5-10, and test the sound after each change.
Mistake 2: Using applications with questionable permissions
Some "sound boosters" request access to the SMS, Not only is it a privacy risk, but it's also a sign that the app isn't working with audio drivers, it's just filtering. Solution: use only proven software from official sources (Google Play, XDA Developers).
Mistake 3: Neglecting backup before modifications
Editing mixer_paths.xml Or firmware custom recavery without backup can lead to "bricking" the device. Solution: before any changes, create a backup through the device. TWRP Or Mi Flash Tool.
Error 4: Replacement of speaker without compatibility check
Installing a speaker with 4 Ohms impedance instead of a regular 8 Ohm will overload the amplifier and potentially cause the sound chip to fail, so choose speakers with identical parameters or use a matching resistor.
Mistake 5: Ignoring hardware constraints
The Redmi Note 5 has a weak audio tract β the maximum power of the amplifier is 1.2 watts. Attempting to squeeze more will lead to clipping and damage to the circuit. Solution: if you want a loud sound, consider buying external acoustics or changing the device to a model with stereo speakers (for example, the Redmi Note 10 Pro).

Most of the sound problems on the Redmi Note 5 are software-solved. Hardware modifications are only justified if you are willing to risk losing the device or spending money on repairs.
