Talk speaker on Xiaomi does not work: all the reasons and how to fix

Have you noticed that the person you are talking to has stopped hearing you while you are on the phone, and the voice commands of the Xiaomi AI Assistant are ignored? Or maybe the speaker makes strange wheezing while you are talking and the sound is gone? Problems with the speaker (or microphone) on Xiaomi devices are one of the most common malfunctions, but in 80% of cases it can be fixed by yourself without going to the service center.

In this article, we will look at all possible causes, from simple errors in settings to hardware breakdowns, as well as give step-by-step instructions for diagnostics and repairs. Particular attention will be paid to the Redmi Note 10/11/12 models, POCO X3/X4, Mi 11/12 and smart speakers Xiaomi Smart Speaker, where the problem occurs most often. If after reading you still do not find a solution, at the end of the article there is an FAQ with answers to rare cases.

1. Check basic settings: sound and microphone

Before disassembling the phone or carrying it for repair, make sure that the problem is not in the software settings. Often users accidentally turn off the microphone during a call or activate modes that block the sound.

Start with the simplest:

• 🔊 Volume level: Press the up/down volume buttons during the call - it's possible the sound is just set to a minimum. On some Xiaomi models, the volume control of the conversational speaker is separated from the media sound.
• 🎤 Microphone during call: tap the microphone icon on the call screen (if it is crossed out, the microphone is turned off.
• 📵 Do Not Disturb Mode: Check if it is activated in the settings (Settings) → Sound. → Do not disturb. This mode can block both incoming calls and microphone operation.

If after these manipulations the problem remains, move to the next step: on models Xiaomi 12T and Redmi Note 12 Pro+ there is a bug when after updating MIUI microphone turns off in the background – in this case, only resetting the audio settings (more about this below) will help.

2.Diagnostics of hardware problems: speaker vs microphone

Many users confuse a speaker malfunction (the interviewer can't hear you) with a speaker problem (you can't hear the person you're talking to) to determine exactly what's broken, run a simple test:

1. Check the microphone: record a voice message on WhatsApp or Recorder, and if the recording is silent, jammed or absent, the microphone is a problem.
2. Speaker check: call another phone and turn on speakerphone. If there's a sound, the speaker is working, if not, it's malfunctioning.

Also pay attention to the side symptoms:

• 🔇 Wheezing / crackling in dynamics - a sign of moisture or mechanical damage to the membrane.
• 🌊 Echo during a conversation – may indicate a noise reduction malfunction or a conflict with the headset.
• 🔌 The speaker works only on speakerphone - a typical symptom of a disconnected conversational speaker (on the phone). POCO F3 redmi K40 This is a common problem after falls).

3. Software glitches: resetting settings and updates

If the hardware diagnostics didn't reveal any problems, the software is to blame.

• 🐞 baga MIUI After the update (especially relevant) MIUI 13/14 old-model).
• 📱 Conflict of apps using a microphone (e.g. Google Assistant and Xiaomi) AI simultaneously).
• 🔄 Failure in the sound settings after connecting Bluetooth headset.

Decisions:

1. Resetting sound settings: Settings → System → Resetting settings → Resetting sound settings This will return all volume, notifications and microphone settings to factory.
2. Cleaning the cache of applications related to sound: Settings → Applications → Application Management → [Select Phone, Google, Mi AI] → Storage → Clear the cache
3. Related: Retreat of the update MIUI (If the problem has occurred after the update): 💡Before rolling back, make a backup of the data in Settings → The phone. → Backup! Settings! → The phone. → Updating the system → Click on the version. MIUI 10 times → Choose the old firmware

On Xiaomi Smart Speaker, similar problems are solved by rebooting through a button on the case (hold 10 seconds) or resetting to Mi Home (Device Settings → Additional → Reset).

4. Conflicts with headsets and Bluetooth devices

One of the most insidious reasons is when the phone forgets to switch from a Bluetooth headset to a built-in microphone/speaker, which is especially true for models with Qualcomm Snapdragon (such as the POCO X3 Pro or Redmi K50), where audio drivers sometimes get bugged.

How to check:

• 🎧 Disable all Bluetooth devices and restart your phone.
• 🔌 If you use a wired headset, disconnect it and check the connector for contamination (on Xiaomi, contacts are often oxidized).
• 🔄 Turn on/off the Settings mode → Connected devices → Bluetooth → Additionally. → Absolute volume.

If the problem persists, reset your Bluetooth settings:

Settings → Connected devices → Bluetooth settings → Resetting settings

⚠️ Attention: On some firmware MIUI after the headset is connected through USB-C (Xiaomi Type-C Earphones, for example, shuts down the main microphone permanently until you restart the phone, a bug that Xiaomi hasn't fixed since 2021.

Moisture, dust and mechanical damage

Xiaomi devices (except for the flagship Mi 13 Ultra or Redmi Note 12 Pro+) do not have official water protection according to the IP68 standard. Even short-term moisture ingestion can cause corrosion of contacts of a conversational speaker or microphone.

Signs of moisture intrusion:

• 💧 The screen displays a warning “Moisture in the charging connector” (even if the phone is not sinking).
• 🔊 The sound becomes muffled, wheezing, as if the speaker is "bubbling».
• 📱 The phone overheats in the lower part of the case (there are speakers and microphones).

What to do:

1. Turn off the phone immediately and remove it. SIM-map.
2. Place the device in a silica gel bag (out of a shoe box) for 24 to 48 hours. Don't use a hair dryer or rice! This will only exacerbate corrosion.
3. After drying, check the speaker. If the problem remains, you need a replacement (on the Redmi Note 10 and similar models, the speaker costs ~ 500-800 rubles).

6. Repair with your own hands: when possible

If you're sure that the hardware is the problem, you can fix some of the faults yourself, but remember, disassembling the phone is insecure (if it's still in effect) and can lead to additional breakdowns.

What you can fix yourself:

• 🔧 Clean connectors: If the speaker or microphone is not working due to oxidation, gently wipe the contacts with alcohol (90%+). For hard-to-reach places, use a toothpick.
• 🔩 The lift of the speaker mounts: on Redmi 9A/9C often leaves the plume of the speaker - it can be pressed back (you need a plastic mediator).
• 🔊 Replacement of the speaker grid: if the sound is quiet due to the dust-clogged mesh, it can be removed and washed under a stream of water (pre-disconnecting the phone!).

What can't be done:

• ❌ Disassemble the phone without special screwdrivers (risk of damaging the plumes).
• ❌ Try to solder a microphone or speaker without experience (on boards Xiaomi small contacts that are easy to damage).
• ❌ Use glue or tape to fix parts (this can block the speaker's vibration).

⚠️ Note: On Xiaomi models with IR-A blaster (like the Redmi Note 8 Pro) is often confused with an infrared port. Don't try to clean it with alcohol - these are optical lenses that spoil from liquid!

💡

If you've stopped turning on after you've disassembled, you've probably damaged the battery plume or the display, and you need professional repair.

7. When to contact the service center

There are situations when self-repair is not possible or advisable.

• 🔧 The speaker or microphone is physically damaged (cracks, dents).
• 🔥 On the board, traces of oxidation or burnt elements are visible.
• 📱 The phone does not recognize the speaker even after flashing (fastboot shows speaker error: no device).
• 🔄 The problem only appears under certain conditions (such as high temperature or low battery charge).

Official Xiaomi service centers in Russia:

• 📍 Moscow: 16 Leo Tolstoy St. (at the Afimall shopping center»).
• 📍 St. Petersburg: Ligovsky Prospect., 10/118 (at the Leroy Merlin hypermarket»).
• 📍 Regions: addresses can be found on the website mi.com/ru/service/center.

The average cost of diagnosis is 500-1000 rubles. If the phone is warranty, repair will be free (but the warranty does not apply to damage from moisture!).
