Xiaomi’s Redmi Note series has traditionally been known for its excellent value for money, but Redmi Note 8 owners often face a situation where the speaker volume or headphone output is not enough. This can happen for a variety of reasons, from the software limitations of regional firmware versions to the customization of the audio codec in the Android system.
Fortunately, the MIUI operating system that runs the device provides the user with advanced options for fine-tuning the audio stream. Unlike many other manufacturers, Xiaomi allows you to interfere with the sound engine, change the parameters of the equalizer and even accessing hidden engineering menus. Volume increase is not just a digit increase in the slider, but complex work with the software.
In this guide, we’ll look at all the legal and safe ways to make headphones louder and richer.We won’t recommend installing questionable modified firmware that could disrupt your device. Instead, we’ll focus on the standard features, hidden developer settings, and proven apps from Google Play that will make the most of your Xiaomi Redmi Note 8.
Basic Volume and Multimedia setting
Before you go to complex manipulations, you need to make sure that all the basic settings are done correctly. Often users forget that Android has a volume level divided into several independent channels. For media content (music, video, games), a separate slider responds, which can not be twisted to the end, even if the call rings loudly.
Press the side volume button and notice the scale that appears. There should be an arrow or setting icon on the left or right of it. When you click on it, you will see the separation of channels. Make sure that the Media slider (or Music) is raised to its maximum position. It is also worth checking whether Do Not Disturb or Quiet Mode mode is activated, which can programmatically limit the maximum sound level.
The important aspect is the quality of the connection. If you use a Bluetooth headset, make sure that the Bluetooth settings include the option "Absolute Volume Level". This synchronizes the phone and headphone sliders, allowing you to control them together. For wired headphones, check if the plug is tightly inserted into the 3.5 mm connector, as the oxidation of the contacts can create resistance and reduce the signal level.
- 🎧 Check that the type of device “Hearphones” is selected in the sound settings, not “Dynamic».
- 🔊 Make sure that in the player application (YouTube, Spotify, Yandex.Music) your own volume slider is also twisted to the maximum.
- 📱 Reboot the device to reset temporary audio drivers that may have “hanged».
💡
Use the original 3.5mm USB-C adapter if your Redmi Note 8 doesn't have a minijack or it's faulty. Cheap Chinese counterparts often don't have a built-in DAC (digital-to-analog converter), resulting in a quiet and hoarse sound.
Use of the built-in MIUI equalizer
The MIUI shell on the Redmi Note 8 hides a powerful sound tool, the system equalizer, which many users ignore when relying on music app settings, but the system equalizer processes sound at a lower level, affecting the entire audio stream of the device regardless of the application running.
To access these settings, go to the Settings menu, then select Sound and Vibration. At the bottom of the screen or in the optional settings menu (three dots or gear), look for Sound Effects**. Here you will find some preset profiles like Pop, Rock, Jazz, but we are interested in manual settings.
Choose a user profile or Custom profile. You will see a frequency graph. To increase perceived volume without distortion, it is recommended to slightly raise the average frequencies (about 1 kHz) and high frequencies. Low frequencies (bass) should not be raised too high, as this can cause "porridge" in sound and clipping on budget headphone speakers.
⚠️ Warning: Don’t push all the equalizer sliders to maximum position, which will lead to digital distortions (wheezing), which will not only worsen the sound quality, but can also damage the membrane of the headphones due to overload.
Also on the audio effects menu is often the option "Mi Sound Enhancer"**. If your region allows it to be used (not available in some versions for RF / CIS without changing the region), be sure to activate it. Select the type of headphones ("Normal headphones" or "Earbuds-in-ears"), so that the system applies the optimal algorithm for signal amplification.
☑️ Equalizer setting
Configure through the Engineering Menu (CIT)
One of the most effective ways to increase volume on Xiaomi devices is to adjust the levels of gain in the engineering menu, which allows you to change the software limit of maximum volume set by the manufacturer for a specific region. However, this requires caution, since you interfere with the low-level settings of the audio codec.
To enter the engineering menu on Redmi Note 8, open the Phone app and enter a special code: ##6484##. This will trigger the CIT (Customer Interactive Test) mode. In the test list that opens, you need to find the item associated with the sound, usually called "Media"**, "Speaker" or "Headset." In different versions of MIUI, the numbering of the items may differ, so look carefully.
And if you go into the audio test menu, you'll see some sliders or Gain input fields, and we're interested in the parameters that produce the sound on the headphones (Headset/Headphone). These are usually levels for different modes, like "Normal," "Headset," "Handsfree," and increasing the values in these fields directly raises the maximum volume threshold.
| Parameter (Gain) | Description | Recommended action |
|---|---|---|
| Headset Gain | Total volume for wired headphones | Increase by 5-10 units |
| Media Volume | Multimedia flow level | Check and maximize |
| Call Volume | Volume of the interlocutor (does not affect the music) | Don't touch unnecessarily |
| Alarm Volume | Loudness of alarm clock | Can be increased separately |
⚠️ Warning: Write down the initial values before you change! If you raise gain too much, the sound will become hoarse, and in the worst case, you can burn the audio codec or the headphone speaker.
After changing the values, remember to click the button "Set"**, "Apply" or "Save" (name depends on the menu version), otherwise the changes will not take effect.Reboot the device after the procedure is mandatory for the correct initialization of new parameters by the audio driver.
What if the code doesn't work?
Sound amplifiers for Android
If MIUI is not enough, third-party apps from the Google Play store come to the rescue. They work as a software amplifier, passing an audio signal through their filter before sending it to the output. There are several proven solutions for Xiaomi Redmi Note 8 that work stably on Android 9 and 10.
One of the leaders in this niche is the Precise Volume app, which allows you to create detailed volume profiles for each application separately, you can set the amplification of +20% or +40% for a YouTube or VLC player, leaving system sounds at a standard level, which gives flexibility that is not available in standard settings.
Another popular option is the Volume Booster GOODEV, which is minimalist and lacks advertising in the basic version, and has one main slider that increases the overall volume of the system, and although it is simple, it does a good job, but requires careful use.
- 🔊 Super Volume Booster: Simple app with the ability to increase volume to 100% above normal.
It’s important to understand that using such applications increases the power consumption of the processor, as it requires constant processing of the audio stream in real time. On the Redmi Note 8 with its Snapdragon 655 processor, this can lead to slightly faster battery discharge during long-term music listening.
💡
Third-party boosters are a temporary solution, and they can conflict with the MIUI system equalizer, so it is recommended to disable the built-in sound effects before installing them.
Activation of Dolby Atmos and Third Party Codecs
While Xiaomi doesn’t always pre-install Dolby Atmos on all Redmi models, Note 8 owners can often activate this feature or its counterparts through third-party modules or developer settings. surround sound technologies often include dynamic rationing algorithms that make quiet sounds louder and louder ones cleaner.
To activate advanced audio functions, you can try to go to the Developer Menu. To open this item, you need to quickly click on the build number in the About Phone section 7 times. In the developer menu, find the audio-related section and look for options like “Enable absolute volume” or Bluetooth codec settings (AAC, aptX, LDAC).
Turning on an aptX or LDAC codec (if your headphones support these standards) can dramatically improve Bluetooth audio transmission. These codecs transfer more data, allowing the system to more effectively manage dynamic range, making sound subjectively louder and richer without loss of quality.
Also worth mentioning are Magisk modules like the Dolby Atmos Port, but installing them requires unlocking the bootloader and obtaining Root rights.This is an advanced level of modification that may take away your warranty, but gives you full control over the smartphone audio system, allowing you to implement a full-fledged Dolby Atmos from other Xiaomi devices.
⚠️ Note: Installing modules through Magisk and unlocking the bootloader will drop all data from the phone. be sure to make a full backup before starting such procedures.
Optimization of audio quality and streaming
Sometimes the problem is not volume, but the original quality of the audio file. If you listen to low-bitrate tracks (for example, 128 kbps), they can sound quiet and flat even at maximum volume. High bitrate (320 kbps or FLAC) contains more dynamic information, which allows the equalizer and amplifier to work more efficiently.
In the settings of streaming services (Yandex.Music, Spotify, VK Music), make sure that you choose high quality playback. In mobile traffic, applications often automatically reduce the quality to save data, which directly affects the volume and saturation of the sound. Switch the setting to High or Lossless.
For local files, use players with built-in amplification, such as VLC for Android or PowerAmp. In PowerAmp settings, you can turn on direct DAC control (if supported) or configure Preamp in the equalizer, which will give an additional volume gain before the main amplifier.
