How to increase volume on Xiaomi Redmi Note 8 Pro: from basic settings to hidden features

The Xiaomi Redmi Note 8 Pro is one of the most popular mid-range smartphones, but many users are faced with the problem of insufficient volume of speakers or headphones, especially when listening to music in noisy places, watching videos without external speakers or while calling. In this article, we will discuss all possible ways to increase the volume on your device, from standard settings to hidden functions of the engineering menu.

It’s important to understand that the volume limits on the Redmi Note 8 Pro are not just set by the manufacturer: too high a sound level can damage the speakers or hearing. However, if you are confident in your actions and are willing to take risks, some methods will make it possible to squeeze the most out of the hardware of the smartphone. We will also consider safe alternatives – for example, the use of external amplifiers or specialized applications.

This article is suitable for both beginners and experienced users: there are simple solutions (equalizer adjustment) and advanced (system file editing).

1. Basic volume settings in the MIUI system

Before resorting to radical methods, check the standard sound parameters in MIUI. Often the problem is solved in just a few taps.

Open Settings β†’ Sound and vibration. Here you will find sliders for adjustment:

  • πŸ”Š Media Volume – responsible for music, video, games;
  • πŸ“ž Loudness of the call – regulates the sound of incoming calls;
  • πŸ”” Volume of notifications – for message signals and alerts;
  • 🎧 Headphone volume – a separate regulator for connected wired/Bluetooth-device.

Note the Dynamic Volume Control option (could be called Adaptive Sound in newer versions of MIUI). If it is enabled, the system automatically lowers the volume in quiet rooms - turn it off for stable sound.

⚠️ Note: Some of the Redmi Note firmware 8 The maximum volume of the media is limited at the level 70-80% This is done to protect the equipment, and exceeding this threshold can cause distortion of the sound.

Also check if Do Not Disturb or Quiet Mode is activated in the notification curtain, which can block the sound completely or minimize it.

2. Equalizer and sound effects setup

The Redmi Note 8 Pro has a system equalizer built in to amplify the individual frequencies and make the sound louder (by raising high or low tones).

Settings β†’ Sound and vibration β†’ Equator

Here are some presets worth trying to increase volume:

  • 🎡 Rock – enhances the medium and high frequencies, makes the sound more β€œbreakthroughΒ»;
  • 🎀 Pop – raises vocals and upper frequencies, useful for music;
  • 🎧 Headphones – optimized for wired headsets;
  • πŸ”Š Custom - manually lift sliders on 3-6 dB 100 Hz – 1 keto.

Also, check out the Mi Sound Enhancer option, which is available in the same settings and allows you to:

  • πŸ”Ή Strengthen the bass;
  • πŸ”Ή Expand the stereo effect (useful for headphones);
  • πŸ”Ή Optimize the sound for a specific genre of music.

If the system equalizer seems weak, install a third-party application, such as Equalizer FX or Wavelet (requires root for full functionality), which offers more flexible settings and can increase volume by 10-15% due to software processing.

To quickly open the equalizer while listening to music, tap the speaker icon in the notification panel and hold it for 2 seconds.

3.Use of the engineering menu (without root)

The Engineering Menu is a hidden settings section where you can manually adjust the hardware settings of your smartphone, including the volume of the speakers. On the Redmi Note 8 Pro, it is accessed via standard code ##36446337## (EngineerMode).

After you enter the code, select Hardware Testing β†’ Audio. Here you are interested in the following options:

  • πŸ”Š LoudSpeaker Mode - external speaker test. Check the maximum level (max vol value);
  • 🎧 Headset Mode – settings for headphones;
  • πŸ“ž Receiver Mode – Volume of Speaking Speaker;
  • πŸ”„ Type – Choose Media for Multimedia or Ring for Calls.

In Volume, you will see the current volume values (0 to 255). By default, the maximum is usually set to 160-180. Do not raise the value above 200 - this can cause distortion or damage to the speakers. The optimal range for experiments is 180-190.

⚠️ Warning: Changes to the engineering menu are not saved after the device is restarted. To fix the new settings, write down their values and re-enter them every time you turn on the smartphone. Also avoid changing the Impedance settings (resistance) - this can cause the speakers to fail.

If the sound is hoarse or intermittent after the changes, return the values to the standard (usually 160 for media and 128 for calls).

What to do if the engineering menu is not opened?
If the code ##36446337### doesn't work, try alternatives: 1. #4636## β†’ go to the Phone Information tab β†’ Select Test β†’ Audio. 2. Install the MTK Engineering Mode app from Google Play (requires permission to access system settings). 3. Update the firmware - in older versions of MIUI, some codes may be disabled.

4. Volume up through configuration files (requires root)

For users with unlocked bootloaders and root rights, the most effective method available is editing the system files responsible for volume limits, which gives a constant result, but requires caution.

You'll need:

  • πŸ“± Root access (for example, via Magisk);
  • πŸ› οΈ Root-enabled file manager (e.g., Root Explorer or Solid Explorer);
  • πŸ“ Backup of original files (required!).

Instructions:

  1. Open the file manager and go on the way: /system/vendor/etc/ Find the file. mixer_paths.xml (or mixer_paths_tasha.xml firmware).
  2. Copy the file to a secure location (e.g., on the SD-map).
  3. Open it in a text editor (like QuickEdit).
  4. 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!).
  5. Save the file and restart the device.

For headphones, look for the <path name="headphone"> block and edit similar settings. After the changes, the volume will increase by 15-25%, but be prepared for possible distortions at the maximum level.

⚠️ Attention: Incorrect editing mixer_paths.xml This can cause a complete loss of sound or looping of the system boot. If the smartphone stops turning on after the changes, restore the original file through the system. TWRP.

Make a backup of the original mixer_paths.xml

Check root rights (Magisk must be active)

Use a text editor without formatting

Not exceed the value of value = 95

Prepare. TWRP repair-->

5. External amplifiers and accessories

If software methods don’t work, consider hardware solutions that are safer for your smartphone and often provide better sound quality.

Here are some proven options:

Accessory typeExamples of modelsVolume up.Price (roughly)
Portable Bluetooth amplifierFiiO BTR3, SoundMagic A30+30-50%2 000 – 5 000 β‚½
Wireed headphone amplifierFiiO A1, Topping NX1S+40-60%1 500 – 4 000 β‚½
External speaker with AUXJBL Go 3, Xiaomi Mi Portable Speaker+100% and higher1 000 – 3 000 β‚½
Active headphones with enhanced bassSony WH-CH710N, Xiaomi Hybrid Pro+20-30%3 000 – 8 000 β‚½

The Redmi Note 8 Pro is particularly relevant to Bluetooth amplifiers, as they do not require root and connect in seconds. For example, the FiiO BTR3 supports aptX HD and can output audio directly from the phone without loss of quality.

If you need maximum volume to listen to music in noisy places (such as the subway), look for passive noise-canceling inserts like the Xiaomi Hybrid Pro HD. They fit tightly to the ear canal and block out external noises, allowing you to listen to music at a lower volume.

πŸ’‘

External amplifiers not only increase the volume, but also improve the sound quality due to built-in DAC (digital-analog converters).

Problems with speakers: diagnostics and repair

If the volume suddenly drops or the sound becomes hoarse, the problem can be a hardware malfunction.The Redmi Note 8 Pro is known for several typical speaker defects:

  • πŸ”Š Grid pollution speaker - dust and pile build up over time, lowering volume. Clean the hole with a soft brush or compressed air;
  • πŸ’§ Moisture infestation - even a little humidity can cause contacts to corrosion. If the phone falls into the water, it requires disassembly and cleaning;
  • πŸ”Œ Oxidation of plume contacts is a common problem after a year of operation, solved by soldering or replacing the plume;
  • πŸ”„ Software failure – sometimes helps resetting settings to factory (Settings) β†’ The phone. β†’ Resetting settings).

To check the performance of the speakers:

  1. Connect headphones – if the sound in them is normal, the problem is in the external dynamics;
  2. Record a video with the sound on and play it back – if there is no sound, the microphone or plume is defective;
  3. Call your phone from another device – if the person you are talking to hears you poorly, the problem is in the conversational speaker.

The cost of repair speaker in the service center:

  • πŸ”§ Replacement of external speaker: 800–1,500 β‚½;
  • πŸ”§ Replacement of the plume (together with the speaker): 1,200–2,000 β‚½;
  • πŸ”§ Cleaning from moisture/dust: 500–1000 β‚½.

⚠️ Warning: If you decide to clean the speaker yourself, do not use sharp objects (needles, toothpicks) - they can damage the membrane.

7. Alternative methods: applications and chips MIUI

If you don’t want to dig into settings or risk hardware, try these simple solutions:

  • 🎡 Amplifiers: Volume Booster – Increases volume by 20-30% by software processing; Equalizer + β€” combines equaliser and booster; ViPER4Android β€” Powerful audio processor (requires root).
  • πŸ”Š The function of "Smart Assistant" in MIUI: Activate Settings β†’ Special facilities β†’ Smart assistant. β†’ This will increase the volume of notifications and calls for people with hearing impairments.
  • 🎧 Bluetooth 5.0 and aptX codec: If you use wireless headphones, turn on the aptX codec or AAC For better quality and volume, go to Settings. β†’ Connected devices β†’ Headphone settings.

For music lovers, Dual Audio (available in MIUI 12+) will be useful, allowing you to connect two Bluetooth devices at the same time (e.g. headphones and a speaker) and play audio on both. Activated in Settings β†’ Bluetooth β†’ Dual Audio.

If you often listen to music via Bluetooth in your car, turn off the Absolute Volume feature in the Bluetooth settings, allowing you to adjust the volume directly from the tape recorder, rather than from your smartphone.

FAQ: Frequent questions about volume on Redmi Note 8 Pro

πŸ”Š Why After Updating MIUI loudness has become quieter?
In newer versions of MIUI (especially MIUI 12.5+), Xiaomi has tightened the limits on maximum volume to protect speakers: Try: Reverse to the previous firmware version; Use the engineering menu for manual tuning; Install custom software (such as Pixel Experience).
🎧 Can I increase the microphone volume during calls?
Yes, for this: Open the engineering menu (##36446337##); Go to Audio β†’ Normal Mode β†’ Mic; Increase the Mic Volume values (maximum 255, but not recommended above 200). Also check if the microphone hole is covered with a cover or film.
πŸ”‹ Does the increase in volume affect battery consumption?
Yes, but not much. At maximum volume, speakers consume 5-10% more power than average, but the main expense goes to processing the audio processor, especially if you use amplifiers or equalizers. Tip: turn off unnecessary sound effects in Settings β†’ Sound β†’ Additional to reduce the load.
πŸ› οΈ Can you repair the speaker yourself?
Theoretically, yes, but in practice, it's risky. The Redmi Note 8 Pro speaker is soldered to the plume, and you need to replace it with: a soldering station; a new speaker (article: 18050-0837-00); Tweezers and a T3 screwdriver. Without soldering experience, you risk damaging the plume or the motherboard. Better contact the service.
πŸ“± Why the sound is quieter in headphones than on the speaker?
This is normal behavior for most smartphones. Manufacturers limit the volume in headphones to protect hearing. To make up the difference: Use low impedance headphones (16-32 ohms); Activate the equalizer and raise high frequencies; Connect an external amplifier (such as the FiiO A1).
