How to tune the keystroke sound on the Xiaomi Redmi 9 keyboard: the complete guide

The audio signals when typing on Xiaomi Redmi 9 is not just a nice thing, but an important feedback element that helps control input. However, many users are faced with the fact that the keyboard sound suddenly disappears, does not work correctly or does not turn on after a system update. In this article, we will discuss all the ways to adjust the sound effects for standard and third-party keyboards, as well as consider typical problems and their solutions.

The Redmi 9 feature is that the audio settings may vary depending on the version of the MIUI and the keyboard used (built-in Gboard, SwiftKey or proprietary Mi Keyboard).We will dwell on each option in detail so you can choose the best one for yourself, you will learn how to change the volume of the keys sounds regardless of the overall volume of the device and why sometimes the sound only works in some applications.

Why is there no sound on Redmi 9 when typing?

The lack of sound when you press keys is one of the most common problems, and there are several reasons, and most of them are easily remedied:

• 🔇 The sound turned off in the keyboard settings is the most obvious reason that many people overlook.
• 🔊 Total media volume at zero – keyboard sounds are classified as “media”, so their volume depends on this regulator.
• 📱 Failure after update MIUI — Often the sound settings are reset when switching to a new firmware version.
• 🎹 Third-party keyboard conflict – if you use Gboard or SwiftKey, their settings may overlap system settings.
• 🚫 Do Not Disturb – In some modes of operation (for example, “Meeting” or “Sleep”), the keyboard sounds are automatically turned off.

Before you start setting up, check if the sound works in other applications (for example, in a player or when playing video). If there is no sound at all, the problem may lie in the speaker or volume settings. If there is sound, but not when typing, move to the next sections.

⚠️ Note: On Redmi 9 with custom firmware (like LineageOS or Pixel Experience), the path to keyboard settings may be different. In this case, use the universal methods in the "Configuration through the Engineering Menu" section".

How to turn on the keyboard sound in the standard Mi Keyboard

The Mi Keyboard is installed by default on all Xiaomi smartphones, including the Redmi 9.

1. Open any typing application (such as Messages or Notes).
2. Touch the gear badge (⚙️) on the keyboard to open its settings.
3. Go to Sound and Vibration (or Keyboard Settings → Sound depending on the MIUI version).
4. Activate the keyboard switch.
5. If you wish, choose a tune from the options offered (usually available 3-5 sounds).

If the keyboard settings do not have the "Sound" option, try an alternative path:

Settings → System and device → Language and input → Virtual keyboard → Mi Keyboard → Sound and vibration

In some versions of MIUI 12-14, the audio settings can be hidden deeper, and if you don’t find the right item, update the keyboard via Google Play or reset it to factory settings (reset option in the keyboard menu).

Make sure that the volume of the media is not at zero.

Check if the "Do Not Disturb" mode is on.

Restart your smartphone if the sound disappears after the update-->

Customize the sound in Gboard and other third-party keyboards

If you use Gboard (a keyboard from Google) or other alternatives like SwiftKey, the process of turning on the sound will be different. Consider Gboard, as it is the most popular third-party keyboard among Xiaomi users:

1. Open any text field and call the keyboard.
2. Press the gear icon (⚙️) keyboard.
3. Select Settings → Sound when pressed.
4. Activate the switch and select the sound you like (there are 4 options available in Gboard).

For SwiftKey, the path will be as follows:

SwiftKey settings → Sound and vibration → Keyboard sound

An important caveat: if you have multiple keyboards installed at the same time, the audio settings may conflict, for example, if the Mi Keyboard has sound on and Gboard doesn't, then the behavior will be unpredictable when you switch between them, and we recommend choosing one keyboard and disabling the rest in the system settings:

Settings → System and device → Language and input → Virtual keyboard → Keyboard management

⚠️ Note: In Gboard, the default key sounds are tied to the system media volume, but their level can be adjusted separately in the keyboard settings (Speech Volume).This is useful if the overall sound on the phone is loud and the keyboard is too quiet.

How to change the volume of keyboard sounds separately from the total volume

One of the little-known features of MIUI is that it can independently adjust the volume of the keyboard, which is especially useful if you want the sound of the presses to be quieter than music or notifications, and you can do this in two ways:

Method 1: Through audio settings (for MIUI 12 and later)

1. Go to Settings. → Sound and vibration.
2. Click on Additional Settings (or Advanced Settings).
3. Choose Media Volume.
4. In some versions, there will be a separate slider for keyboard sounds.

Method 2: Engineering Menu (Universal Method)

If there is no separate regulator in the standard settings, use the engineering menu:

1. Open the Phone app and enter the combination: ##36446337###.
2. Go to the Hardware Testing → Audio section.
3. Choose Type → Media.
4. In Keyboard Volume, set the desired volume level (0 to 7).

Important: Changes to the engineering menu are applied immediately and do not require a reboot, but when resetting settings or updating the firmware can be reset.

Classic "click" (standard)

Troubleshooting: Keyboard sound doesn’t always work

If the sound of the keyboard appears, then disappears, the problem may lie in the following factors:

• 🔄 Automatic switching of sound profiles to MIUI There is a Smart Switch function that can turn off keyboard sounds in certain conditions (for example, at night or when the battery is low).
• 📴 Application-specific restrictions – some messengers (such as Telegram or WhatsApp) can block keyboard sounds due to their internal settings.
• 🔋 Battery savings – in super-saving mode, keyboard sounds can be turned off automatically.
• 🛠️ Keyboard cache failure – temporary files can interfere with sound effects.

To diagnose the problem:

1. Check if the sound works in different applications (e.g. Messages and Browser).
2. Turn off battery saving mode: Settings → Battery and performance → Battery mode → Standard.
3. Clear the keyboard cache: Settings → Annexes → Application management → [Your keyboard] → Warehouse → Clear the cache.
4. Check the Smart Switch settings: Settings → Sound and Vibration → Smart Switch.

Hidden features: how to make the keyboard sound unique

Few people know, but Redmi 9 not only allows you to play standard keyboard sounds, but also customize them to suit you.

• 🎵 Custom setup — you can replace the standard keys with your own tunes, and you need a.ogg file or a.ogg file.mp3 lasting no more than 1 second.
• 🔄 Different sounds for different keys - in some firmware (for example, MIUI EU) It is possible to assign unique sounds for letters, numbers and symbols.
• 🎚️ Keyboard equalizer – through the engineering menu you can adjust the frequency characteristics of sounds, making them more bass or high-frequency.
• 🔇 Automatically turn off the sound in headphones – you can configure so that the sounds of the keyboard are played only through the phone speaker, but not through Bluetooth headphones.

To set the custom sound:

1. Download or create a sound file (for example, via mp3cut.net).
2. Place the file in /sdcard/Media/Audio/Notifications/ (create it if it doesn't exist).
3. Use an app like Zedge or Ringtone Maker to assign it as the keyboard sound.
4. Reboot your phone to make the changes take effect.

⚠️ Note: When replacing system sounds with custom ones, make sure the files are the correct name and format. Wrong files can cause the keyboard to crash. Recommended format: keypress.ogg for pressing sound and keyrelease.ogg for key release sound.

💡

If you want the keyboard to be heard only by you, plug in your Bluetooth headphones and turn on the Media Audio feature in your audio settings, so that the sound is played only on your headphones without disturbing others.

What to do if the keyboard sound is gone after the MIUI update

MIUI updates often result in a reset of the audio settings. If the keyboard sound stopped working after the update, follow these steps:

1. Check out MIUI version: Settings → About Phone → MIUI version Remember version number (e.g. MIUI Global 14.0.5).
2. Reset keyboard settings: Settings → System and device → Language and input → Virtual keyboard → [Your keyboard] → Reset settings
3. Clear the system settings cache: Settings → Annexes → Application management → Three points (⋮) → Show system-based → Settings → Warehouse → Clear the cache
4. Reinstall Keyboard: If you use Gboard or SwiftKey, uninstall and re-install them via Google Play.
5. Reverse update (if the problem has appeared after the last update): Settings → Annexes → Application management → [Your keyboard] → Three points (⋮) → Remove updates

If none of these methods worked, maybe the new version of MIUI changed the way to audio settings.

• Check the official Xiaomi forum for similar complaints.
• Install the keyboard beta (if available) via Google Play.
• Contact Xiaomi for support with the phone model and MIUI version.

💡

After major MIUI updates (e.g., version 12 to version 13), the audio settings can be transferred to another menu. If you don't find the right item, try searching by settings (the magnifying glass icon in the upper right corner).
