Speaker Not Working or No Sound: How We Fix This

You play a video and hear nothing. Calls go through but the other person cannot hear you, or you cannot hear them. No sound from your phone can stem from several different faults, and at Pro-Logic Technologies, we diagnose speaker and audio faults accurately before recommending any parts replacement.

The Phone's Audio Components

Most smartphones have multiple audio components:

• Earpiece speaker — the small speaker at the top of the phone used during regular calls.
• Loudspeaker — the main speaker at the bottom or back used for media, speakerphone, and ringtones.
• Microphone — captures your voice during calls, videos, and voice messages.

A fault in any one of these produces different symptoms, which helps us pinpoint the issue quickly.

Common Causes of No Sound

• Debris blocking the speaker grille — dust, lint, and pocket debris can clog the speaker grille to the point where almost no sound passes through.
• Stuck in headphone mode — dirt or debris in the headphone jack (on phones that have one) can make the phone think headphones are connected, routing audio away from the speaker.
• Damaged speaker component — physical damage from a drop, or water ingress, can physically damage the speaker membrane or coil.
• Software audio routing error — OS bugs or app conflicts can cause audio to be routed incorrectly or muted entirely.
• Speaker connection fault — the speaker's flex cable or connector can work loose internally.

Step 1: Software and Settings Check

We check for software mutes, Do Not Disturb mode, media volume levels, and Bluetooth audio routing. We also test whether audio is present through headphones — if it is, the fault is in the speaker pathway, not the audio system overall.

Step 2: Grille Cleaning

We clean speaker grilles thoroughly. A clogged grille is responsible for muffled or absent sound far more often than people expect. Safe, thorough cleaning often restores full volume without any repair.

Step 3: Speaker Replacement

If the speaker component itself is damaged, we replace it with a correctly matched unit. Speaker replacement is typically a straightforward repair at Pro-Logic Technologies.

Bring your silent phone to Pro-Logic Technologies — we will have it sounding clearly again.
