iPhone Speaker or Microphone Not Working? Try These Fixes

Callers say you sound far away. Your ringtone is silent. Videos play with no sound, or the earpiece crackles during calls. Audio problems are among the most common iPhone complaints, and many of them can be fixed without a repair. If your iPhone speaker is not working or your microphone has gone quiet, start here.

Know which part is failing

Your iPhone has more than one speaker and more than one microphone:

• Earpiece speaker: at the top of the screen, used when you hold the phone to your ear.
• Loudspeaker: at the bottom, used for ringtones, speakerphone, music and videos. On many models, the earpiece also works as a second speaker for stereo sound.
• Microphones: typically one at the bottom for calls, plus others near the front and rear cameras for video and noise reduction.

Knowing which one is affected makes troubleshooting much faster.

Check the simple settings first

1. Volume: press the volume up button while playing a video, and check the volume slider in Control Centre.
2. Silent mode: check the Ring/Silent switch or, on models that have one, the Action button setting.
3. Bluetooth: make sure the phone is not sending sound to earbuds, a car or a speaker. Turn Bluetooth off briefly to test.
4. Focus and Do Not Disturb: these can silence calls and notifications.
5. App permissions: if the mic only fails in one app, check Settings > Privacy & Security > Microphone.
6. Restart and update iOS.

Clean the speaker and microphone openings safely

Lint, dust and makeup build up in speaker grilles and microphone holes, muffling sound. To clean them:

• Use a soft, dry, clean brush (a new soft toothbrush works) to gently brush the grilles.
• Remove any case or screen protector that might cover the earpiece or mic holes.
• Do not push pins, needles or toothpicks into the grilles, and do not use liquids or compressed air, which can push debris deeper or damage the mesh.

Test each microphone

These quick tests help you pinpoint the problem:

1. Bottom mic: open Voice Memos, record yourself speaking, and play it back.
2. Front mic: record a short video with the front camera and play it back.
3. Rear mic: record a short video with the rear camera and play it back.
4. Speakerphone: make a test call on speaker. If people can hear you normally on speaker but not on a regular call, or the other way around, that points to a specific mic.

If one recording is muffled or silent while the others are clear, that particular microphone or its opening is the problem.

iPhone speaker not working? When it is hardware

Signs you need a repair include:

• Crackling, rattling or distorted sound at normal volume.
• No sound from the loudspeaker even after cleaning and checking settings.
• A greyed-out speakerphone button during calls, which can indicate a deeper audio fault.
• Audio problems that started after a drop or after the phone got wet. If yours got wet recently, read what to do when your iPhone gets wet.

Depending on the diagnosis, a repair may involve replacing the earpiece or loudspeaker, replacing a charging port assembly that includes a microphone, or, in some cases, board-level work on the audio circuit. You can read about that in what is micro soldering and when a device needs it.
