Why Xiaomi Redmi 8 might be missing sound and how to fix it

Xiaomi Redmi 8 is a popular 2019 model that is still in use today for its balanced performance and reliability. However, even time-tested gadgets have software failures, and one of the most common problems is the sudden disappearance of sound. Users face the speaker not working while calling, music is quiet, and system notifications remain silent.

In this article, we’ll look at all the ways you can turn on your Redmi 8, from checking the obvious parameters to diagnosing hardware components, how to turn back the volume of calls, restore media playback, and what to do if your smartphone goes deaf after the MIUI update. And if the problem is more serious than it seemed, we’ll give you recommendations for further action.

Before you start settings, make sure that the problem is not related to physical damage. For example, if the smartphone fell or came into contact with moisture, the sound may disappear due to damage to the speaker or plume. In such cases, it is better to contact the service center immediately. If there is no external cause, follow our instructions in order.

💡

If the smartphone does not respond to the power button, try to pinch Volume up + Power for 20 seconds - this will force the device to restart.

3. Diagnostics of hardware problems

If the software methods didn't work, it's worth checking the physical condition of the speakers and connectors. On the Xiaomi Redmi 8, the sound is output through two speakers: the main (bottom) and the conversational (top).

• 🔈 Check the main speaker: Turn on music or video and put your ear on the bottom of your smartphone. If there's a sound but it's very quiet, it may be clogged with dust. Carefully clean the holes with a soft brush or compressed air.

• 🎧 Test through headphones: Connect wired or wireless headphones. If they have sound in them, but not through the speakers, the problem is precisely hardware.
• 🔌 Check the 3.5mm connector (if any): Sometimes the smartphone "thinks" that the headphones are connected and turns off the speakers. insert and remove the headphones several times or clean the jack from dust.

1. Open the Phone app.
2. Press three points (⋮) top-right.
3. Select Settings → Smart response and turn off the function.

5. Software update and reset to factory settings

If the sound is lost after updating MIUI or installing a new application, the problem may be a software conflict.

• 📲 Remove recent apps: Remove programs that were installed before the problem occurred (especially if they requested access to a microphone or speakers).

If the microphone is running in the recorder but doesn't work while calling, the problem is with the phone app or network settings. Try using alternative call software (like Google Phone).

7. When to contact the service center

If none of these methods worked, it's probably a hardware problem, and here are some signs you should call in the experts:

⚠️ Warning: If the smartphone fell into the water or was subjected to a strong vibration (for example, in a pocket while running), the speaker or microphone could suffer mechanical damage.

• 💧 Liquid intake: Even if the smartphone did not sink, condensation or moisture could oxidize the contacts.
