iPhone Speaker or Microphone Not Working? Complete Fix & Repair Guide for iPhone 11 to 18

You pick up an important call and the other person says, "Hello? I can't hear you." Or you press play and the iPhone speaker crackles, sounds muffled or stays completely silent. Audio problems are among the most frustrating iPhone faults because the phone looks perfectly healthy yet cannot do its most basic job. In this guide, we explain how the speakers and microphones in the iPhone 11 to iPhone 18 series work, the 12 most common reasons they stop working, quick tests you can run in two minutes at home, and the repairs we carry out in our Safdarjung Enclave workshop when the fix needs a technician.

How iPhone audio hardware works

Understanding the layout makes troubleshooting far easier. Every modern iPhone has three audio systems:

• Earpiece speaker – the thin grille at the top of the screen. It plays your phone calls and, on current models, also acts as the second channel of the stereo speakers.
• Loudspeaker – at the bottom edge, next to the charging port. It plays ringtones, music, videos, speakerphone calls and alerts.
• Microphones – there are several: one at the bottom for calls, one near the front camera for FaceTime and video calls, and one on the rear near the camera for video recording and noise cancellation.

Each of these is a separate component, so one can fail while the others work. That is why careful testing is the first step to a correct repair.

Two-minute tests that tell you what is broken

Write down which of these fail. That tells you whether the fault is a single speaker, a microphone or something deeper such as the audio chip.

12 reasons your iPhone speaker or microphone is not working

1. The phone is stuck in headphone mode

Sometimes the iPhone thinks headphones are connected when they are not, and routes audio to a non-existent device. Moisture or lint in the port can cause this. You will see a headphone icon next to the volume bar even with nothing plugged in.

2. Silent mode or volume settings

Check the ringer switch (or Action Button on newer models), the Ringer and Alerts slider in Settings → Sounds & Haptics, and whether Focus or Do Not Disturb is turned on. It sounds obvious, but these settings account for a large share of "my speaker is dead" visits.

3. A connected Bluetooth device

If your iPhone is connected to a car, earbuds, a smartwatch or a Bluetooth speaker in another room, calls and music go there instead. Open Control Center and check where audio is playing.

4. Dirt or debris in the speaker grille

Dust, pocket lint and skin oils block the tiny speaker mesh over time. The sound becomes muffled or quiet. A gentle clean with a soft, dry brush can bring it back. Never poke the mesh with a pin.

5. Screen protector or case blocking the openings

A badly cut tempered glass can cover the earpiece grille, and a case with misaligned cut-outs can muffle the bottom speaker or microphone. Remove both and test.

6. Water or liquid damage

Water in the speaker causes crackling, distortion or total silence, often after a delay as corrosion forms. Read how to deal with a water-damaged device before charging or using the phone again.

7. Software glitch or failed update

After an iOS update the audio system can misbehave. Restarting the phone often corrects this. If not, a software repair or reinstall may be needed.

8. Noise Cancellation or accessibility settings

In Settings → Accessibility → Audio & Visual, features such as Phone Noise Cancellation, Mono Audio and Balance can change how calls sound. If one ear or one side seems weak, check the balance slider.

9. A damaged speaker or earpiece component

Drops, age and repeated loud playback can physically damage the speaker cone. The result is crackling, buzzing or no sound at all, even when software settings are correct.

10. A faulty microphone

Mic holes block easily with dirt, or the microphone component fails after a fall or liquid damage. People hear you faintly, or only on speaker, or not at all on WhatsApp calls.

11. A damaged charging port flex cable

On many iPhones the bottom microphone and sometimes the speaker connections run through the same assembly as the charging port. If a damaged port is the cause, both can fail together. See our iPhone charging port repair guide.

12. An audio chip or board fault

If every speaker and microphone is silent, calls show greyed-out speaker and mute buttons, and the phone sometimes shows "Voice memos can't record", the audio codec chip on the logic board may have failed. This needs board-level repair; we call it the "grey speaker button" fault.

What you can safely try at home

1. Restart the iPhone. Switch it off for 30 seconds and turn it back on.
2. Check volume, silent mode and Focus as listed above.
3. Disconnect Bluetooth from Control Center.
4. Remove the case and screen protector and test again.
5. Clean the openings gently with a soft, dry brush or a clean toothbrush with the phone off. Avoid liquids and metal tools.
6. Plug and unplug headphones a few times to reset the audio route if it is stuck in headphone mode.
7. Update iOS from Settings → General → Software Update.
8. Reset all settings (not "Erase All Content") from Settings → General → Transfer or Reset iPhone → Reset. This keeps your data but resets configuration.

If none of these helps, the fault is almost certainly hardware.

Prevent iPhone audio problems

• Use a case with correctly aligned speaker and microphone cut-outs.
• Choose a screen protector that leaves the earpiece mesh open.
• Keep the phone away from water, steam and humid pockets.
• Avoid listening at maximum volume for long periods.
• Clean the speaker openings regularly with a dry soft brush.
• Do not use the phone in bathrooms and kitchens near steam.

If your phone is also hot or shuts down, read iPhone overheating: causes and repair, and if the phone will not start, see iPhone not turning on.

The microphone works in one app but not another: what is going on?

A very common complaint is that "people hear me on normal calls but not on WhatsApp" or "Instagram videos have no sound". When the microphone works in some places and not others, the hardware is usually healthy and the problem is a permission or an app setting:

• Open Settings → Privacy & Security → Microphone and make sure the app is switched on.
• Close the app completely and reopen it. A stuck app can hold the microphone in a busy state.
• Check whether another app, such as a screen recorder or a voice assistant, is using the microphone in the background.
• Turn off Voice Isolation or Wide Spectrum in Control Center during a call and see if sound improves.
• Update the app from the App Store; old versions sometimes break after an iOS update.

If the microphone fails everywhere, including in the Voice Memos app and in video recordings, then the hardware is at fault and needs repair.

Sound is fine on speaker but weak on calls: the earpiece story

Because the earpiece sits right behind the display grille, it picks up dust, hair oil and skin cells quickly, especially if you hold the phone against your face during long calls. Over a year or two the mesh clogs and the voice on the other end sounds distant. We often see this on iPhone 11 and iPhone 12 models that have never been cleaned. A professional cleaning under magnification is inexpensive and brings the volume straight back. If the earpiece also buzzes at high volume, the speaker itself has aged and is replaced.

Also remember that the earpiece doubles as the top stereo speaker on modern iPhones. When it fails, music and videos sound lopsided and thin even in speaker mode, which many people mistake for a "software problem".

Do "speaker cleaning" sounds and water-eject shortcuts really work?

You will find videos online that play a low-frequency tone to "push the water out" of an iPhone speaker, and Shortcuts that do the same. These can help shift a few droplets from the grille after a splash, but they do nothing for corrosion, wet circuits or a damaged component. Use them only for a minor splash, never as a substitute for proper drying, and never when the phone has fallen into a bucket, sea or washroom. If the speaker still sounds wrong after drying, have it checked.

When to stop troubleshooting and visit a technician

• The audio problem started after a drop or water exposure.
• Both the earpiece and the loudspeaker are silent, or the speaker button on calls is greyed out.
• A restart, an update and a settings reset all failed to help.
• People cannot hear you in Voice Memos and video recordings either.
• The sound crackles even at low volume.

Continuing to blast the speaker at full volume to "clear" it can damage a weakened speaker further. A free diagnosis tells you exactly which part is at fault before you spend anything.
