The Xiaomi Redmi Note 8 Pro is still one of the most popular smartphones among price-performance users. However, many owners are faced with the quiet sound of a conversational speaker — a problem especially relevant in noisy rooms or when using hands-free. In this article, we will examine all possible ways to increase volume, from standard MIUI settings to deep modifications of the system.
It's important to understand that quiet sound can be caused by software constraints (the manufacturer deliberately lowers the volume for safety) and hardware problems - a pollution of the speaker or a malfunction of the plume. Before you start settings, check whether the cover or protective film blocks the speaker hole. If the problem persists, read on.
1. MIUI Standard Settings: What You Can Do Without Root
To start with the simplest methods that do not require superuser rights and do not affect the warranty. MIUI offers several built-in tools for adjusting the sound, but they often go unnoticed.
The first thing to check out is the Sound Amplifier mode in the special features settings, which is designed for people with hearing impairments, but also suitable for increasing the volume of a speaker:
- 📱 Open the Settings. → Special facilities → Sound amplifier
- 🔊 Turn on the slider and adjust the gain level (optimally — +5 dB)
- 🎧 Activate the option "Amprovise the sound in the headphones" (works for the speaker)
Another little-known trick is to change the sound profile. By default, the Redmi Note 8 Pro uses a Balanced profile, but some regional firmware has a Loud profile:
- 🔧 Go to Settings. → Sound and vibration → Sound profile
- 🔉 Select Loud (if not, see the next section)
- 🔄 Restart the device to apply changes
2. Engineering menu: hidden parameters of sound
The Redmi Note 8 Pro, like other Xiaomi smartphones, has a hidden engineering menu where you can manually adjust the settings of the speakers. This method does not require root rights, but requires caution - incorrect settings can lead to distortion of the sound.
To open the engineering menu:
- Open the Phone app and enter the combination: ##36446337###
- Select Hardware Testing → Audio → LoudSpeaker Mode
- In the Speaker section, find the parameters: Max Vol - maximum volume (increase by 2-3 units) Gain - amplification (optimally: +6 dB)
Save the settings and restart the phone
Important: values above +8 dB can cause sound distortion and overheating of the speaker. On the Redmi Note 8 Pro, the safe limit is +6 dB for a conversational speaker.
Record the current settings (take a screen picture)
Do not exceed the recommended values (+6 dB)
Do not change the microphone parameters (the quality of communication may deteriorate)
Reboot your phone after the changes-->
Modification of system files (root required)
If standard methods have failed and the warranty on the phone is over, you can try editing system files, which requires root access and backup.
The main file responsible for volume restrictions — /system/vendor/etc/mixer_paths_tasha.xml. It's got maximum values for each type of speaker. 8 Pro are relevant to the following parameters:
| Parameter | Current value | Recommended value | Description |
|---|---|---|---|
| RX1 Digital Volume | 84 | 90 | Digital volume of the conversational speaker |
| RX2 Digital Volume | 84 | 87 | Digital volume of multimedia dynamics |
| Speaker PA Gain | 3 | 5 | Dynamic amplifier boost |
For editing:
- Install Root Explorer or Mixplorer with root rights
- Find the file along the way. /system/vendor/etc/mixer_paths_tasha.xml
- Make a backup copy of the file (copy it to the SD-map)
- Edit the values according to the table above
- Save the file, set the rights 644 (rw-r--r---)
- Reboot the phone.
If the sound has become worse after the changes:
- Return the standard settings to the engineering menu
- Restore the original file mixer_paths_tasha.xml
- Reset the sound settings to Settings → Applications → App management → Sound (Reset button)
💡
On the Redmi Note. 8 Pro safe sound amplification without risk to the equipment - up to +6 dB in the engineering menu or before 90 unit mixer_paths.xml. Exceeding these values leads to distortion and possible failure.
