How to increase volume on Xiaomi Redmi Note 8 Pro: from settings to repair

Why the Redmi Note 8 Pro is quieter: the main reasons

Owners of the Xiaomi Redmi Note 8 Pro often face the problem of low loudness speakers - whether while listening to music, watching videos or talking on speakerphone. The reasons can be both software (failures in settings, MIUI restrictions) and hardware (contamination of speakers, wear of the membrane).

The first thing to check is whether Do Not Disturb or Quiet is activated, which automatically reduces the volume of notifications and media, and the problem can also be hidden in the MIUI updates: after some versions, users complain about artificially limiting the maximum sound level, less often the fault becomes damage to the audio chip (for example, after a fall or moisture).

If the sound used to be louder and now it's quieter for no apparent reason, there's a good chance that the speaker pollution is to blame. Dust, pocket pile or small debris will eventually clog the grid, reducing the amplitude of the sound waves, and in such cases, careful cleaning helps — but more on this in one of the following sections.

Method 1: Volume settings using standard MIUI parameters

Before you climb the engineering menu or install third-party utilities, make sure you make the most of the built-in capabilities of the Redmi Note 8 Pro. MIUI has hidden options that allow you to increase volume beyond standard limits.

Open Settings → Sound and vibration and do the following:

• 🔊 Turn off Adaptive Sound: This feature automatically adjusts volume to ambient noise, but often works incorrectly.".
• 📱 Activate "Sound Amplification": in some versions MIUI This option is hidden. To find it, turn on Developer Mode (7 times click on Version). MIUI Under "About Phone" then go back to Settings → Additionally. → For developers and find the item Turn off absolute volume - it must be turned off.
• 🎵 Set up the equalizer: in the section Sound Quality, select the preset "Bases" or "Rock" - they amplify low frequencies, which subjectively makes the sound louder.

If you still don't like the volume after this manipulation, move on to more radical methods, but remember, exceeding the standard volume limits can cause the sound to be distorted and the speakers to wear out faster.

Method 2: Engineering menus – hidden options for amplifying sound

The Engineering Mode is an Android service section where you can fine-tune hardware components, including the audio system, and the Redmi Note 8 Pro is accessed through special code.

Enter the following combination in the "Phone" app:

##36446337##

Then the Engineer Mode menu will open. Go to Hardware Testing → Audio and select:

• 🔧 LoudSpeaker Mode — you can increase the Max Vol value for the speaker — 160, try to install 180-200.
• 🎧 Headset Mode – Similar setup for headphones (relevant if the sound is quiet when connecting wired headsets).
• 📞 Receiver Mode - volume control of the speaker (useful if the interlocutor is not heard during calls).

💡

Before you change the values in the engineering menu, write down the standard parameters on paper. If you see wheezing or distortion after the changes, return the original numbers.

Be careful: Incorrect settings in Engineer Mode can damage the speakers. If the sound becomes hoarse or intermittent after the changes, immediately return the values to the factory.

⚠️ Note: Some Redmi Note 8 Pro firmware may have the engineering menu blocked, in which case try typing code through the Phone app in dial mode rather than search.

Method 3: Apps to amplify sound - top-3 tested utilities

If standard methods don't work, third-party applications will come to the rescue, working on two principles: either amplify the sound programmatically (via equalizer and compressor), or bypass the limitations of MIUI by unlocking hidden volume levels.

To install ViPER4Android on the Redmi Note 8 Pro, you will need:

1. Get root rights (for example, through Magisk).
2. Download the latest version of the driver from the official ViPER's Audio website.
3. Install APK and run the settings through Settings → Sound → Sound effects.

⚠️ Note: Apps like Volume Booster can burn speakers if you use them at maximum settings, and we recommend that you set the volume to no more than 80% of the available limit in the utility.

Method 4: Cleaning the speakers – when the problem is dust

If the sound is quiet and muted, especially at low frequencies, there is a good chance that the speakers are clogged with dust. On the Redmi Note 8 Pro, the bottom speaker (also known as the main multimedia speaker) is the most vulnerable. You can clean it yourself, but you need to do it carefully so as not to damage the membrane.

You'll need:

• 🧴 Isopropyl alcohol (70% and above) - for dissolving contaminants.
• 🖌️ Soft brush (for example, for drawing or cleaning lenses).
• 💨 A compressed air canister (optional, for blowing out dust).
• 📎 Toothpick or plastic spatula - for careful tweaking of the protective net.

Step-by-step:

1. Turn off the phone and remove it. SIM-memory-card.
2. Carefully tuck the speaker's safety net (it's attached to double-sided tape) Don't pull too hard - there's a thin membrane underneath!
3. Wet the brush in isopropyl alcohol and clean the visible contaminants with light movements.
4. Let the alcohol completely evaporate (10-15 minutes), then set the net back, pressing it tightly.

If the sound has not improved after cleaning, the problem may be damage to the membrane (for example, after the fall of the phone) or detachment of the contacts of the speaker.

Method 5: Hardware Repairs – When Nothing Helps

If all software methods have been tried and the cleaning has failed, the problem is likely hardware.

• 🔈 Dynamics - rupture of the membrane or a break in the power wire.
• 🔌 Audio chip – responsible for sound processing, can burn when short circuit.
• 📶 Antenna switch – affects the sound quality during calls (rare, but common).

Diagnosing a malfunction can be based on the following signs:

The cost of repairs varies:

• Replacement of the speaker: 800-1500 rubles.
• Splintering contacts: 1000-2000 rubles.
• Replacement of the audio chip: 3000-5000 rubles. (often unprofitable).

Before you agree to a repair, ask the wizard to conduct a free diagnostic. On the Redmi Note 8 Pro, the audio chip is soldered into the motherboard, and its replacement requires high qualification. If the phone is warranty, contact the official Xiaomi service - self-repair will deprive you of warranty obligations.

💡

If the sound is gone after a phone drop or moisture, do not try to dry it with a hairdryer or rice. immediately turn off the device and take it to the service - corrosion of contacts can worsen in a matter of hours.

Preventing Sound Problems on Redmi Note 8 Pro

To avoid repeated volume problems, follow simple guidelines:

• 🚫 Do not use your phone at maximum volume for a long time – this leads to wear and tear of the speakers.
• 🧴 Regularly clean the speakers of dust (every 3-6 months) with a soft brush.
• 🔋 Avoid battery discharge to 0% – this can cause malfunctions in the audio chip.
• 📦 Store your phone in a speaker-protected case (such as with silicone stubs).
• 🔄 Update. MIUI, But watch out for reviews about new versions - sometimes updates "break" the sound.

If you often listen to music through your phone’s speakers, consider buying an external Bluetooth speaker. Even budget models (like the Xiaomi Mi Portable Bluetooth Speaker) sound louder and better than the built-in speakers, and also reduce the load on the hardware of the smartphone.

For fans of loud sound, portable acoustics with support for Xiaomi HyperCharge are suitable - it is quickly charged and compatible with Xiaomi's proprietary technologies.
