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

Xiaomi Redmi Note 8T is a popular smartphone with good sound, but many users complain about a quiet speaker while listening to music, watching videos or talking. The reasons can be different from factory restrictions to pollution of the speaker. In this article, we will discuss 7 working ways to increase the volume without harming the device - from basic settings to hidden functions of the engineering menu.

It's important to understand that the volume is not just a function of software constraints, but also of hardware. For example, the Redmi Note 8T's lower speaker is responsible for low frequencies, and the upper speaker is responsible for high frequencies. If one of them is clogged with dust or damaged, the sound will be muted even at maximum settings. So check the physical condition of the device before changing the parameters.

We will not be looking at radical methods like flashing or changing speakers, but rather at safe and reversible solutions, all of which have been tested on current versions of MIUI 12/13/14 and do not require root rights, except for one (specified separately).

1. Check current sound settings

Before you change anything, make sure that the problem is not the basic settings, and often users simply don't notice that the volume is limited at the system or application level.

Open the Settings β†’ Sound and vibration and check:

  • πŸ”Š Media volume - slider should be at maximum. - Redmi Note 8T It is divided into Media and Calls, and they should be regulated separately.
  • 🎡 Equalizer -- turn it on and select the preset Bass or Rock to amplify the low frequencies, which won't increase the overall volume, but will make the sound richer.
  • πŸ“± Do Not Disturb Mode - if it's activated, the sound can automatically mute. Turn it off or set exceptions.
  • πŸ”• Adaptive sound - function in MIUI, It automatically adjusts the volume to the noise around it. Sometimes it doesn't work properly, try turning it off.

Also check the settings in specific applications. For example, YouTube or Spotify may have its own volume control, which override system settings. In messengers (WhatsApp, Telegram), the volume of notifications and calls is separately set.

If the earphones are switched on, check the settings for Settings β†’ Sound β†’ Automatic Sound Switching. Sometimes the system mistakenly determines the connection of accessories.

Cleaning of speakers from dust and debris

One of the most common causes of silent sound is contamination of the speakers. On the Redmi Note 8T, the bottom speaker is located next to the USB-C connector, where dust, pile from your pockets, or particles from your case easily get into, and the top speaker (conversational) can also get clogged over time.

How to clean:

  1. Take a soft toothbrush with a short bristles (or a special brush for the technique). Carefully walk through the speaker grilles without pressing hard.
  2. Use a compressed air canister (sold in electronics stores) Hold it vertically 5-7 cm from the speaker and make short presses.
  3. For persistent contaminants, you can use isopropyl alcohol (70%+) and a cotton swab. Wet the stick, squeeze the excess fluid and gently wipe the grille. Don't pour alcohol directly onto the speaker!

After cleaning, check the sound by playing a low-frequency test file (e.g. bass music). If the volume has grown, the problem was pollution. If not, move on to the following methods.

What happens if you clean the speaker with a wet wipe?
Using wet wipes (even "for engineering") can cause moisture to enter the speaker, causing membrane corrosion or short circuiting. Isopropyl alcohol evaporates quickly and leaves no trace, so it is safer.

3.Use of the engineering menu (without root)

Xiaomi hides some of the audio settings in the engineering menu, which you can access without root rights, but you need to change the settings carefully - incorrect values can worsen the sound quality or cause distortion.

Instructions:

  1. Open the Phone app and enter the combination: ##36446337## Once entered, the EngineerMode (MTK) menu will open.
  2. Go to the Hardware Testing β†’ Audio section.
  3. Select LoudSpeaker Mode (for the main speaker) or Headset Mode (for headphones).
  4. In the Value field next to Max Vol, increase the value by 5-10 units from the current one (for example, from 160 to 170).
  5. Press Set, then restart the phone.

When you change the settings, check the sound at different frequencies. If you have wheezing or distortion, return the previous values. Also note that after resetting the settings or updating the MIUI, the parameters of the engineering menu are reset.

πŸ“Š Have you ever used the engineering menu on Xiaomi?
Yeah, for sound.
Yes, for other purposes.
No, I'm afraid to break my phone.
I didn't know he existed.

4.Applicants for sound amplification

If the system settings don't work, you can use third-party apps, and they work on two principles:

  • πŸ“± Amplifiers – increase volume through processing algorithms (e.g., Volume Booster or Equalizer) FX).
  • πŸŽ›οΈ Equators: Adjust the frequency range to make the sound louder at certain frequencies (e.g., Poweramp Equalizer).

Top.-3 Proven applications for Redmi Note 8T:

AnnexTypePlusesCons
Volume Booster GOODEVPower-upSimple interface, works without rootCan distort the sound at maximum
Equalizer & Bass Boosterequalizer10-band equalizer, presets for different genresAdvertising in the free version
ViPER4AndroidAdvanced equaliserMaximum customization of soundRequires root or magisk to work properly

Check reviews before installing – some apps may conflict with MIUI. Also remember: increasing volume through software increases the load on speakers and can reduce their lifespan.

5. Update firmware and reset settings

Sometimes quiet sound is a firmware bug. Xiaomi regularly releases updates for the Redmi Note 8T, where audio drivers correct errors. Check your version. MIUI:

  1. Go to Settings β†’ About the phone β†’ System update.
  2. If you have an update, install it, preferably via Wi-Fi, to avoid interrupting the download.
  3. After the update, reset the sound settings: Settings β†’ Applications β†’ App management β†’ Sound β†’ Storage β†’ Clear the data.

If the problem has occurred after the update, try rolling back to the previous version (if you had a backup) or wait for the next patch.It's also worth checking the regional settings: some versions of MIUI (for example, for the EU) have volume restrictions due to local regulations.

πŸ’‘

Updating your firmware is the safest way to fix sound problems, but always do a backup before installing new versions of MIUI.

6. Checking for hardware malfunctions

If none of these things worked, there may be a hardware problem. The Redmi Note 8T is the one that fails most often:

  • πŸ”ˆ The bottom speaker is responsible for bass and general volume, and when damaged, the sound becomes quiet and empty".
  • πŸ“Ά Audio chip – if the sound is lost completely or distorted in all speakers, the problem may be in the chip.
  • πŸ”Œ Contacts of speakers – oxidation or break of the plume (especially after falls or moisture hits).

How to diagnose:

  1. Connect headphones – if the sound in them is normal, the problem is with the speakers or their connection.
  2. Call your phone from another device – if the person you are talking to hears you poorly, the microphone or audio track is faulty.
  3. Shake the phone next to your ear – if you hear a noise, it is possible that the speaker’s plume has disconnected inside.

If you suspect a hardware malfunction, it is better to contact a service center. Self-repair without experience can aggravate the problem. The average cost of replacing a speaker with a Redmi Note 8T is 800-1500 rubles (depending on the region).

πŸ’‘

Before visiting the service, make a factory reset (Settings β†’ Additional β†’ Recovery and Reset) and sometimes this helps to distinguish a software failure from a hardware failure.

7. Alternative ways to amplify sound

If standard methods do not give a result, you can go for small tricks:

Use of external amplifier:

  • 🎧 Connect your phone to a portable Bluetooth speaker or amplifier (such as the Xiaomi Mi Bluetooth Speaker.
  • πŸ”Œ Use an external DAC (digital-to-analog converter) through USB-C. It will improve the sound quality and will allow you to squeeze the maximum from the speakers.

Settings for specific scenarios:

  • 🎬 For video: on YouTube or Netflix, enable the "Improving Sound" or "Normalizing Volume" option in your playback settings".
  • 🎡 For music: Use apps with support LDAC (e.g. Poweramp for wireless lossless sound transmission.
  • πŸ“ž For calls: activate in Settings β†’ Special facilities β†’ Amplifies the sound (if there is such a point).

You can also experiment with positioning your phone, for example, if you put the Redmi Note 8T screen down on a solid surface, the sound from the bottom speaker will resonate and appear louder (but that’s a temporary solution).
