How to increase the volume of the speaker on Xiaomi through the engineering menu: a safe way

Are you tired of the quiet sound in the Xiaomi Redmi Note 12 or POCO X5? Is the music in the headphones stunning, and the speaker barely audible even at maximum? The problem is not always in the hardware - often the restrictions put firmware MIUI. Manufacturers deliberately lower the volume to protect the speakers from overload and comply with local regulations (for example, European standards). EN But if you're willing to take a chance, the engineering menu will get around these limitations.

In this article, you can find a step-by-step photo guide on how to increase volume through hidden settings Xiaomi, Redmi and other devices. POCO. We'll take it:

• 🔓 How to open the engineering menu on different models (including the new Snapdragon 8 Gen 2 and Dimensity 9000 chips)
• 🔊 What parameters are responsible for the volume of the speaker, microphone and headphones
• ⚠️ Risks and how to avoid damage to speakers (spoiler: not all values can be increased)
• 🛠️ What to do if the sound is lost or distortions appear after the changes

Important: The method works on most Xiaomi smartphones with Qualcomm and Mediatek chips, but is not guaranteed on custom firmware devices (like LineageOS or Pixel Experience).If your model is older than 2018 (like Redmi 5 or Mi). A1), Some menu items may not be available.

1. How to open the engineering menu on Xiaomi: 3 working ways

The engineering menu (or Engineer Mode) is hidden from ordinary users, but it can be run through secret codes or applications.

First, check which chip is installed in your device:

1. Open Settings → About the phone → Full spec.
2. Find the processor or platform model.

If you have:

• 🔹 Qualcomm Snapdragon (e.g. Snapdragon) 778G Redmi Note 11 Pro+) — Use the code ##4636## or ##36446337##.
• 🔹 Mediatek Helio/Dimensity (For example, Dimensity. 1080 into POCO X5 Pro - enter ##36446337## or ##8255##.
• 🔹 Don’t know the chip model – try the universal code ##4636## (works on 80% of Xiaomi devices).

Instructions for entry:

1. Open the Phone app.
2. Enter one of the codes above (as if dialing a number).
3. If the code worked, you will see a menu with tabs Information, Battery, Usage statistics, etc.
4. To access the audio settings, go to Hardware Testing → Audio.

If the codes don't work:

• 📱 Install the app MTK Engineering Mode (for Mediatek) or Engineering Mode Shortcut (for Universal Mode).
• 🔧 Use it. ADB-team (required debugging by USB): adb shell am start -n com.android.settings/.DevelopmentSettings Then find the Engineering Mode.

💡

If nothing happens after you enter the code, try typing it in Google’s Phone app (install it from Play Market) rather than a standard call. MIUI.

2. What settings are responsible for the volume of the speaker

In the engineering menu, the sound parameters are divided into several categories.

Note: Min Vol (minimum volume) settings are not recommended to be touched - this can lead to surges in sound when adjusting.

How to find these settings:

1. In the engineering menu, select Hardware Testing → Audio.
2. Next, go to LoudSpeaker Mode (for speaker) or Headset Mode (for headphones).
3. Find the Max Vol parameter and change the value (for example, from 140 to 155).
4. Press Set or Apply to save.

On some models (e.g. Xiaomi) 13T or Redmi K60) path may differ:

• 🔊 Audio → Normal Mode → Type → Media (for multimedia)
• 📞 Audio → Normal Mode → Type → Ring (for calls)
• 🎧 Audio → Headset Mode → Type → Music (for headphones)

Make sure the battery is over 50 times charged%|Back up your audio settings (write down the current values)|Check the speaker for distortion before the changes|Do not increase the value by more than 10-15 units at a time.-->

3. Step-by-step instruction: how to increase the volume of the speaker

Let’s look at the Redmi Note 12 Pro.+ 5G With a Mediatek Dimensity 1080 processor, the steps are similar for other models, but the item names may differ slightly.

Step 1 Open the Engineering Menu

Enter the code ##36446337## → choose MTK Settings → Hardware Testing → Audio.

Step 2. Select the speaker type

Go to LoudSpeaker Mode (for the main speaker) or Headset Mode (for headphones).

Step 3: Change the volume settings

Find the following points and set the values:

• 🔊 Max Vol (Media) – 155 (was 140)
• 📞 Max Vol (Ring) – 145 (was 130)
• 🎵 Max Vol (Music) – 150 (was 135)

Step 4: Save and restart

Press Set. → exit the menu → Make sure you restart your smartphone. Changes apply after the reboot.

Step 5. Check the sound.

Turn on music or video at maximum volume if you have wheezing or distortion:

• ↩️ Reduce the value by 5-10 units.
• 🔇 Check the speaker for dust or damage.

4 Risks and how to avoid damage to speakers

Turning the volume above the safe limits can physically damage the speaker, especially if it's already worn out or clogged.

• 🔥 Overheating of the dynamic coil → distortion of sound ("wheezing").
• 💥 Membrane rupture → phonophobic.
• 🔋 Increased battery consumption (sound chip works with overload).

How to minimize the risks:

⚠️ Note: Do not increase the Max Vol by more than 15 units from the factory value. For example, if the default is 140, you can set the maximum 155).

Additional precautions:

• 🛡️ Before changing the parameters, check the speaker for dust (blow with compressed air or gently clean with a soft brush).
• 📉 Don’t listen to music at maximum for more than 30 minutes in a row – let’s relax the dynamics".
• 🔄 Regularly return to the factory settings (every 2-3 months) and check whether the sound quality has deteriorated.

If there are any changes after the changes:

1. Reduce Max Vol by 5 units and check the sound.
2. If the wheezing is left, return the factory settings and contact the service (possibly the speaker has already been damaged).

💡

It is safest to increase the volume gradually: first by 5 units, test 1-2 days, then add another 3-5 units if necessary.

5. Alternative ways to increase volume without an engineering menu

If the engineering menu is not available or you are afraid to take risks, try these methods:

1. uniformity settings (Equalizer)

V MIUI There is a built-in equalizer that can amplify the sound:

1. Open the Settings. → Sound and vibration → Sound settings → equalizer.
2. Choose Bass or Rock presets, which amplify the low and medium frequencies.
3. Manually lift sliders 100Hz and 1kHz to +3-4 dB.

2. Sound amplification applications

Some programs increase the volume of software (without changing system files):

• 🎧 Equalizer FX — equalizer with pre-enhancement.
• 🔊 Speaker Boost – Increases volume by 20–30% (not all models).
• 🎵 Sony Music Equalizer – ClearAudio Support+ sound-enhancing.

3. Firmware update

Sometimes low volume is a firmware bug. Check the updates.

1. Go to Settings → About the phone → System update.
2. If a new version of MIUI is available, install it.

4. Cleaning the speaker

A clogged speaker sounds quieter. How to clean:

• 🧹 Use a soft toothbrush (without alcohol!).
• 💨 Blow with compressed air (a canister for cleaning equipment).
• 🚫 Do not use needles or toothpicks – they will damage the membrane.

Frequent problems and their solutions

Problem 1: The sound became hoarse after the volume increased

Reason: the speaker can't handle the load.

• Reduce Max Vol by 5-10 units.
• Check the speaker for physical damage (dust, moisture).

Problem 2: Changes to the engineering menu are not saved

Reason: MIUI It resets the settings after it resets:

• Repeat the changes and restart the phone immediately.
• Use Engineer Mode MTK parameterize.

Problem 3: There is no Audio item in the engineering menu

The reason: your model uses a different path.

• Try the code #8255## (for Mediatek).
• Install the MTK Engineering Mode application.

Problem 4: After the changes, the sound in the headphones disappeared

Reason: Headset Mode settings are down.

• Return Max Vol (Headset) to factory value (120–125).
• Reboot the phone.
• Check the headphones on another device.

💡

If after manipulating the engineering menu, the phone began to brake, reset the cache: turn off the device → Hold the volume up + Nutrition → Choose the Wipe Cache.
