Why the standard volume on the Redmi Note 8 Pro may be disappointing
Owners of the Xiaomi Redmi Note 8 Pro often face the problem of insufficient loudness of speakers โ especially when listening to music in noisy rooms or during calls. The manufacturer limits the maximum sound level for security reasons (risk of damaging the speakers) and compliance with EU regulations. However, these restrictions are not always justified: the hardware of the smartphone is capable of more.
The MTK Engineer Mode is a hidden tool based on the MediaTek Helio G90T chipset that allows you to bypass software constraints. But it's important to understand that changing the sound parameters can overheat the speakers, distort the sound at high frequencies or even physically damage the membrane. This article will help increase the volume without critical consequences if you follow the instructions strictly.
Before you start settings, check:
- ๐ Clean speakers (dust and dirt reduce volume by 20-30%)
- ๐ฑ The relevance of the firmware (in older versions) MIUI The engineering menu may not be available)
- ๐ง Quality of audio files (beat tracks sound quieter)
Preparing for the Engineering Menu: What You Need to Know
The engineering menu on the Redmi Note 8 Pro is a low-level tool for diagnosing and calibrating hardware components. It's not designed for the average user, so:
- ๐ ๏ธ No official support: Xiaomi is not responsible for damages after menu changes.
- ๐ Risk of resetting settings: Some settings may reset after rebooting.
- ๐ Loss of warranty: If the smartphone fails, the service center will refuse repairs under warranty.
Before entering the menu, back up important data (contacts, photos, messages) via Settings โ About Phone โ Backup. Also make sure the battery is above 50% โ this will eliminate sudden shutdown during settings.
Backup data | Charge phone to 50%+| Check the clean speakers | Make sure the firmware is up-to-date-->
โ ๏ธ Warning: If the speaker starts wheezing or making extraneous noises after the changes to the engineering menu, return the standard settings immediately. Continued use in this mode will lead to irreversible damage to the acoustic system.
Step-by-step: how to log into the engineering menu on Redmi Note 8 Pro
There are two ways to open the engineering menu on the Redmi Note 8 Pro:
- Open the Phone app, type ##3644633## and press the call. After a short download, the MTK Engineer Mode menu will open.
- Through Settings: Go to Settings โ About Phone, tap 7 times on the MIUI Version. Go back and a new section will appear Additional โ For Developers โ Engineering Menu.
If none of the methods worked:
- ๐ฑ Update the firmware to the latest version MIUI (Engineering menu may not be available in custom assemblies).
- ๐ง Install the app MTK Engineer Mode from Play Market (requires superuser rights).
- ๐ Check if the developer rights are disabled in Settings โ Additionally. โ For developers.
After a successful login, you will see a menu with tabs Hardware Testing, Telephony, Connectivity, etc. To customize the sound, you need a tab Hardware Testing โ Audio.

If the engineering menu opens in Chinese, change the system language of the phone to English and translate the menu interface.
Setting the volume of the speakers: what parameters to change
In the Audio Engineering menu section, the following options for volume setting are available:
| Parameter | Description | Recommended value | Risks. |
|---|---|---|---|
| Speaker Mode | Dynamic mode (multimedia, calls, alarm clock) | Media (for music) | No. |
| Type | Type of configuration (hardware/software) | HW (Hardware) | With SW, changes will reset after rebooting |
| Level | Volume level (0-160) | 120-140 (max. safe limit) | Over 150 โ Risk of distortion |
| Max Vol. | Maximum volume limit | 140-150 | Over 155 - overheating dynamics |
Algorithm of changing parameters:
- Choose Speaker Mode โ Media.
- Install Type โ HW.
- In the Level field, type 130 (start with this, then test the sound).
- Press Set to save.
- Check the sound on different tracks (bass, high frequencies).
Critical value for Redmi Note 8 Pro: limit of 150 units, exceeding this threshold by more than 10% leads to nonlinear distortion and risk of physical damage to the speaker membrane after 2-3 months of intensive use.
What if the sound becomes hoarse after the change?
Alternative ways to increase volume without an engineering menu
If working with an engineering menu seems risky, consider these methods:
Sound amplifiers applications:
- ๐ต Volume Booster (Play Market) โ Increases volume 20-30% software-based processing.
- ๐ Equalizer FX โ allows you to adjust the equalizer and increase low / high frequencies.
- ๐ฑ Mi Sound Enhancer (built-in) MIUI) โ activated in Settings โ Sound. โ Improvement of sound.
MIUI settings:
- Activate Settings โ Sound โ Volume amplification in headphones (works for speakers as well).
- Turn on Settings โ Special features โ Sound amplification (increases the volume of system signals).
- Turn off Settings โ Sound โ Safe Volume Mode (limits maximum level).
Physical methods:
- ๐งน Clean the speaker with a soft brush or compressed air (dust blocks up to 30% of sound).
- ๐ถ Use a case with an acoustic resonator (increases the volume by 10-15%).
- ๐ Check the battery: at a discharge below 15% MIUI automatically reduces volume.
โ ๏ธ Note: Voice Booster, Speaker Boost applications often contain ads or require root rights. Install them only from official sources (Play Market) and check reviews. Some utilities can damage the speaker due to improper signal processing.
Frequent Mistakes and How to Avoid Them
Users often make these errors when setting volume through the engineering menu:
1. Too drastic an increase in the level
- ๐ซ Error: Set Level = 160 at once.
- โ Solution: Increase volume in stages (10 units) by testing the sound after each step.
Ignoring dynamic modes
- ๐ซ Error: Change Level for all modes (Media, Ring, Alarm) at the same time.
- โ Solution: Set each mode separately, for example, you can set the Alarm Level. = 140, and for music (Media) 130.
Annexes not verified
- ๐ซ Error: Installation of sound amplifiers from unverified sources (APK-file).
- โ Solution: Only use apps from the Play Market with a rating above 4.5 and installations >100K.
4. Neglect of testing
- ๐ซ Error: Do not check the sound at different frequencies after the changes.
- โ Solution: Play bass, medium and high frequency tracks. If you get wheezing or distortion, reduce your Level to the lower end of the spectrum. 5-10 unit.
๐ก
The most common error is changing the Type setting from HW to SW. In this case, the settings will reset after the reboot, and the user will think that the changes have not survived.
How to return standard settings if something goes wrong
If after changes in the engineering menu there are problems (wheezing, lack of sound, distortion), follow the following steps:
Reset via engineering menu:
- Return to MTK Engineer Mode โ Audio.
- Select the desired mode (Media, Ring, etc.).
- Set Level = 100 (standard value).
- Press Set and restart the phone.
2. Resetting the sound settings in MIUI:
- Go to Settings โ System โ Resetting settings.
- Select Reset Sound Settings (does not affect personal data).
- Confirm the action and wait for the process to be completed.
3. Complete reset of the phone (in extreme cases):
- ๐ Save all important data.
- ๐ฑ Go to Settings. โ The phone. โ Resetting settings.
- ๐ Choose Delete all data and confirm.
โ ๏ธ Attention: If the sound has not recovered after resetting, the problem may be hardware. In this case: Check the speaker for physical damage (bloating, cracks). Connect the headphones - if the sound is normal, the problem is dynamics. Contact the service center (repair speaker on Redmi Note) 8 Pro is worth it. ~1500-2500 ruble).
