How to really increase the volume of the speaker on Xiaomi Redmi Note 8T: from MIUI settings to engineering menu

Xiaomi Redmi Note 8T is one of the most popular smartphones in the budget segment, but many users experience the quiet sound of a conversational speaker during calls. The problem is especially relevant in noisy rooms or when using hands-free. In this article, we will discuss 7 working ways to increase the volume, including hidden MIUI settings, engineering menus and hardware solutions without the risk of damaging the device.

It's important to understand that the Redmi Note 8T's volume limit is not just a problem, it's a protection against sound distortion and overheating, but if you're willing to take a little risk (or even do without it), our methods can help you get 20-40% louder when talking, start with the safest options and gradually move on to the advanced ones.

1. Check basic sound settings in MIUI

Before you go to the engineering menu or install third-party apps, make sure that the problem is not in the standard settings. On the Redmi Note 8T with MIUI 12-14, there are several options that can quietly turn down the volume:

• 🔊 Do Not Disturb: Check if it is activated in the Sound and Vibration settings → Even in "Alarms Only" mode, the volume of calls can go down.
• 📞 Voice amplification: in the menu Settings → Special facilities → Enable the option "Amprovement of voice during the call".
• 🔄 Resetting sound settings: sometimes resetting to factory settings helps → System system → Resetting settings → Resetting the sound settings.

Pay special attention to the sound profile. The Redmi Note 8T can default to either Quiet or Normal, switch to Loud in the audio settings, and check if there are volume limits on apps like Google Phone (if you use it instead of a standard caller).

💡

If the speaker's volume goes down spontaneously after the bell, it could be a contamination of the speaker's grid, and clean it carefully with a soft brush or compressed air, which often solves the problem without software intervention.

2.Use of the Engineering Menu (MTK Engineer Mode)

The Redmi Note 8T is built on a Qualcomm Snapdragon 665 chipset, but unlike many other Xiaomi smartphones, its engineering menu is available through standard code. This allows you to manually increase the volume of the speaker without root rights. Important: the wrong settings in the engineering menu can lead to audio distortion or damage to the speaker!

Instructions for increasing volume:

1. Open the Phone app and enter the code ##36446337# (or ##ENG##).
2. Go to Hardware Testing → Audio → LoudSpeaker Mode.
3. Select Sph (Speak Speaker) and set the Level value to a maximum (usually 160 or 255).
4. Save the settings and restart the phone.

If the sound is hoarse or distorted after the changes, return the Level to 140-150. The optimal value for the Redmi Note 8T is 150-160, but it can vary depending on the batch of the device. Remember: increasing the volume above 160 is fraught with physical damage to the speaker!

Make sure that the battery charge is > 50%

3. Sound amplification applications: what really works

There are hundreds of apps on Google Play that promise to increase the volume of the speaker, but 90 percent of them are empty. We tested the top-end solutions on the Redmi Note 8T and we selected 3 really working ones:

The best result was shown by Precise Volume, but it must be allowed to work through ADB:

adb shell pm grant com.photonconnect.pvolume android.permission.WRITE_SECURE_SETTINGS

Once you install the app, open it, select Call Volume and set the value 10-15 units above the standard maximum.If the sound starts to "tear up," reduce the value by 2-3 units. Samsung's SoundAssistant works well on MIUI 12, but can conflict with system updates.

4. Modification of files mixer_paths.xml (advanced)

This method requires an unlocked bootloader and root rights, but it gives the most stable result. mixer_paths.xml Contains volume limits for all Redmi Note audio devices 8T. Its editing allows you to remove software restrictions, but with incorrect actions you can lose the sound at all.

Step-by-step:

1. Install Root Explorer or Solid Explorer with root support.
2. Cross the path. /vendor/etc/mixer_paths.xml And back up the file.
3. Find the following lines: <path name="handset-mic"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Replace value="84" with value="92" (maximum for Redmi Note 8T).
4. Save the file, set the rights to 644, and restart the phone.

After the modification, check the sound in a quiet room. If you have wheezing, go back to 90 or 88. This method gives you a 30-40% increase in volume, but it is not recommended for beginners - an error in the syntax of the file will lead to loss of sound.

5. Hardware solutions: cleaning and replacement of the speaker

If software methods fail, the problem may lie in the physical state of the speaker. On the Redmi Note 8T, two hardware malfunctions are common:

• 🧹 Clogging of the mesh speaker: dust and dirt reduce volume by 15-20%. Cleaning with a soft brush or compressed air can return the original volume.
• 🔧 Contact detachment dynamics: when the contacts fall, they can move away from the board.
• 🔊 Dynamic wear: over time, the membrane loses its elasticity; replacement with the original speaker (article) MDY-007) worth ~500-800 ruble.

For self-cleaning dynamics:

1. Turn off the phone and remove it. SIM-map.
2. Carefully tuck the speaker grid with a plastic card (it is on clips).
3. Remove the dust with a brush or tweezers. Do not use metal objects!
4. Blow the speaker with compressed air (a canister for cleaning equipment).

If the sound hasn't improved after cleaning, contact the service.Replace the speaker with the Redmi Note 8T borrower 20-30 It takes minutes and doesn't require a complete disassembly of the phone. 300 ruble.

💡

Before cleaning the speaker, make sure to check if there is a film or cover on the phone that covers the sound holes, which often cause a "quiet" sound.

6. Alternative methods: headphones and Bluetooth

If you can not increase the volume of the speaker, consider workarounds:

• 🎧 Wired headphones with a microphone: even budget models (for example, Xiaomi Basic) will give a clearer sound than the built-in speaker.
• 🔗 Bluetooth headset: devices like Redmi AirDots or Haylou GT1 protocol AAC, hearable.
• 📱 Speaking to the second phone: connect the Redmi Note 8T Bluetooth to another smartphone and use its speakers.

For owners of the Redmi Note 8T with MIUI 13+, there is another life hack: turn on the dual speaker in the audio settings. While the main speaker remains the same, connecting the second (multimedia) speaker to voice calls can improve audibility.

1. Go to Settings → Sound and vibration → Additional settings.
2. Activate the option of Dual speaker for calls (if it is available in your firmware version).

This method does not increase the volume of the speaker directly, but distributes the load between the two speakers, which improves the perception of sound in noisy conditions.

💡

If you make frequent calls in your car, use the magnetic holder of your smartphone next to the duct, and the sound from the speaker will be amplified by the resonator generated by the airflow.

7. firmware of the custom core (for enthusiasts)

The most radical way is to install a custom core like FrancoKernel or ElementalX, which allows you to fine-tune the sound parameters.

• Unlocked loader
• Installed TWRP
• Experience with firmware

Advantages of the custom core:

• 🔊 Ability to increase the volume to 120-130% standard
• 🎛️ Set up an equalizer for a conversational speaker
• 🔋 Optimizing energy consumption during calls

Risks:

• 🚨 Loss of guarantee
• 🔊 Possible distortions of sound
• 📱 Risk of "bricking" of the device

If you decide to do this, follow the instructions in the 4PDA forum for Redmi Note 8T (theme "Firmware for Redmi Note 8T"). The recommended core is ElementalX, as it has a built-in Flar2 Sound Mod.

⚠️ Attention: Installing a custom core will void Xiaomi's warranty. Before firmware, make a full backup through TWRP Make sure the kernel version is compatible with your firmware MIUI.

FAQ: Frequent questions about volume increase

If none of these methods worked, it's worth considering hardware diagnostics. On the Redmi Note 8T, the problem of quiet speaker is often related to the oxidation of contacts on the motherboard - this is treated only in the service center. Remember: safety is more important than volume - do not increase the values above the recommended values, so as not to damage the speaker forever.
