Sound problems on Xiaomi devices are one of the most common malfunctions users experience, ranging from accidental button pressing to software failure. In this article, we will explore all the possible ways to turn on the sound on the brand’s smartphones, tablets and TVs, and how to diagnose the problem and avoid it in the future.
It's important to understand that the algorithm depends on the type of device and its model, for example, on the Redmi Note 12 and Mi 11 Ultra, the audio settings may be slightly different, and on Mi TVs the interface is completely different, and we tried to cover all the current scenarios so that you can quickly return the sound without going to the service center.
If after reading the article the problem remains - check if it is not due to hardware malfunction (for example, damage to the speaker or connector).
1. Check the basic sound settings on Xiaomi smartphones
Before you start complex manipulations, make sure that the sound is not turned off at the software level, most often users accidentally press the volume button or activate the "Do Not Disturb" mode.
Here's what you need to do first:

- 🚫 Turn off Do Not Disturb mode in the notification curtain or through Settings → Don't disturb.
If you don't have a sound after that, move on to the next section, and also look at the sound profile, which may be Quiet or Meet mode, which limits the volume.
⚠️ Note: On some models (e.g, POCO F5) The default volume buttons only regulate the volume of the call, not the media. To change this, go to Settings. → Sound. → Loudness of buttons and select "Multimedia".
2. Enable sound through the engineering menu (for advanced users)
If standard settings don't work, you can try activating the sound through an engineering menu, which is suitable for advanced users, as incorrect actions can lead to failures.
Instructions for smartphones:

- You will be taken to Engineer Mode. Go to Hardware Testing → Audio.
- Select Normal Mode and check all available speaker tests (Speaker, Receiver, Headset).
- If there's a green checkmark next to the speaker, the hardware is in good working order.
On Mi TVs, the engineering menu opens differently:
- 📺 On the remote, simultaneously press the Menu buttons. + Up (shooting) for 5 seconds.
- 🔧 In the menu, select Factory Settings. → Audio Test and start the speaker check.
⚠️ Warning: Do not change other options in the engineering menu unless you are sure of their purpose.This may lead to loss of warranty or unstable operation of the device.
☑️ Checking the sound through the engineering menu
3. Resetting the sound settings to factory
If the sound is gone after a system update or application installation, resetting the sound settings will help, which does not affect personal data, but returns all volume and notification parameters to factory values.
For smartphones:
- Go to Settings → System → Additional → Resetting settings.

For Mi TVs:
- Open Settings → Device → Reset and Recovery.
- Select Reset sound settings (some models may not have this item – then complete the reset).
After reset, check the sound in different applications: YouTube, Miusic or a standard player. If the problem remains, it may be the software's fault.
What if the reset didn't help?
4.Sound problems on Xiaomi TVs: specific solutions
Mi TVs and Redmi Smart TVs have their own nuances with sound, often with HDMI settings, optical output or external speakers.
Checklist for diagnosis:

If the TV is connected to a sound bar or receiver via HDMI ARC, try:
- Disconnect and reconnect the HDMI cable.
- In the settings of the TV, enable the option HDMI CEC (Settings → HDMI CEC).

6. Hardware malfunctions: when without service can not do
If none of the software methods worked, the problem is probably hardware, and here are the signs that it's time to bring the device to service:
- 🔊 No sound in all modes (calls, multimedia, alarm clock), but the speakers work in the test in the engineering menu.
