🔊 Sound & Audio Problems
When your phone stops making sound — no ringtone, no voice during calls, or music gone silent — it feels like being cut off from everyone who matters.
Common symptoms include:
No sound during calls or media playback
Can’t hear callers unless on loudspeaker
Distorted, crackling, or low speaker sound
People can’t hear you (microphone not working)
Bluetooth or earphones not detecting properly
What’s likely happening:
These issues often come from damaged speakers, clogged audio mesh, faulty microphone circuits, software bugs, or water corrosion affecting the audio IC or connector flex.
Expert Tip:
Avoid poking the speaker or microphone holes with pins or needles — it can push dirt deeper or tear the internal mesh. Try restarting your phone in “safe mode” to rule out app conflicts before visiting a technician.

If you're experiencing any of these symptoms, your phone has a speaker, earpiece, or microphone issue:
You play music, watch videos, or receive calls, but hear absolutely nothing:
Loudspeaker silent – No ringtone, no YouTube audio, no WhatsApp voice notes
Earpiece silent – During phone calls, you hear nothing but caller hears you fine
Both speakers dead – Total audio blackout on your phone
Common scenarios:
Phone fell in water/rain (most common cause)
Dropped phone and sound stopped immediately
Sound worked fine yesterday, dead today for no apparent reason
Volume indicator shows bars moving, but no actual sound
This suggests speaker hardware failure, audio IC damage, or water damage to audio circuits.
⏱️ Typical repair time: 1-2 hours | Success rate: 94% | Most common fix: Loudspeaker or earpiece replacement
You can hear the other person perfectly, but they constantly say:
"Hello? Are you there?"
"I can't hear you, you're breaking up"
"You sound like you're underwater"
"It's just muffled noise"
Tests that confirm mic issue:
Voice recordings sound silent or distorted
WhatsApp voice notes don't work
Siri/Google Assistant can't hear you
Video recordings have no audio
What causes mic failure:
Dust/debris blocking mic hole (tiny hole at bottom of phone)
Water damage to microphone membrane
Physical damage from drops
Audio codec IC failure on motherboard
⏱️ Typical repair time: 1-2 hours | Success rate: 91% | Most common fix: Microphone replacement or cleaning
Sound comes through, but quality is terrible:
Crackling/static – Like listening to broken radio
Robotic voice – Sounds digitized or choppy
Buzzing/humming – Constant background noise
Popping sounds – Random loud pops during audio playback
Volume fluctuates – Gets loud then quiet randomly
When it happens:
During phone calls (earpiece or loudspeaker)
Playing music or videos
Recording voice notes or videos
Using speakerphone
Common causes:
Blown speaker – Speaker cone damaged from max volume or water
Loose internal connection – Flex cable partially disconnected
Audio amplifier IC failure – Chip that boosts audio signal
Software/firmware glitch (less common, but possible)
⏱️ Typical repair time: 1-3 hours | Success rate: 89% | Most common fix: Speaker replacement or audio IC repair
You plug in wired headphones and:
No recognition – Phone doesn't acknowledge headphones plugged in
Sound still plays through speaker instead of headphones
Intermittent detection – Works if you wiggle jack or hold at angle
"Headphone mode stuck" – Phone thinks headphones plugged in when they're not (opposite problem)
For 3.5mm headphone jack phones:
Jack is dirty, corroded, or damaged
Internal pins bent or broken
Water damage to jack assembly
For Lightning/USB-C phones (no headphone jack):
Charging port issue (since audio goes through same port)
Adapter not working
Software not recognizing audio accessory
⏱️ Typical repair time: 1-2 hours | Success rate: 93% | Most common fix: Headphone jack replacement or port cleaning
People can barely hear you during calls:
You have to shout for them to hear
They say you sound "far away"
Voice notes record but very quiet
Video recordings have no/weak audio
What's usually wrong:
Blocked microphone hole – Lint, dust, case covering hole
Water-damaged mic membrane – Works but sensitivity reduced
Partially failed microphone – Component degrading
Software audio gain issue (rare)
Quick test:
Remove phone case
Open Voice Memos/Recorder app
Speak normally 1 foot from phone
Play back recording
Should be clear and loud → If not, hardware issue
⏱️ Typical repair time: 1-2 hours | Success rate: 92% | Most common fix: Microphone replacement or deep cleaning
Modern phones have multiple speakers:
Bottom loudspeaker (main speaker for media, speakerphone)
Top earpiece (for phone calls, also acts as second stereo speaker on some models)
Common scenarios:
Earpiece works for calls, but loudspeaker is silent
Loudspeaker works for media, but earpiece dead (can't hear callers)
Stereo sound only comes from one side (iPhone X and newer)
This is actually good news – confirms audio circuits work (one speaker functional), just one speaker component failed.
⏱️ Typical repair time: 1-2 hours | Success rate: 95% | Most common fix: Replace the dead speaker only
Your phone got wet (rain, spill, drop in sink) and now:
Sound works but sounds "underwater"
Volume is much quieter than before
Crackling when speaker plays
Intermittent audio (works sometimes, not others)
What happened: Water entered speaker/mic chambers. Even if phone still works, moisture affects:
Speaker membrane – Can't vibrate freely when wet
Microphone membrane – Sensitivity drastically reduced
Audio port contacts – Corrosion causing poor connection
🚨 CRITICAL: Even if sound "kind of works," water damage is progressive. Corrosion spreads over days/weeks and will eventually cause complete failure.
⏱️ Typical repair time: 2-4 hours | Success rate: 78% (if treated within 24 hours) | Most common fix: Speaker/mic replacement + motherboard cleaning
Understanding the real causes helps you make smart repair decisions:
What it is: Your phone has tiny electromagnetic speakers (similar to miniature stereo speakers):
Loudspeaker (bottom): For ringtones, music, videos, speakerphone calls
Earpiece (top): For regular phone calls held to ear
How speakers work:
Electrical audio signal sent to speaker
Electromagnet vibrates speaker membrane (cone)
Vibration creates sound waves you hear
How speakers get damaged:
Water/liquid exposure – Membrane absorbs water, can't vibrate properly; corrosion on contacts
Playing at max volume repeatedly – Membrane tears or cone separates from coil
Physical drops/impacts – Speaker knocked loose from mounting or internal wire breaks
Dust/debris accumulation – Blocks speaker mesh, reduces volume over time
Age and wear – Membrane degrades after years of use
Symptoms of blown speaker:
No sound at all (complete failure)
Distorted/crackling sound (partial tear)
Very quiet even at max volume (blocked or damaged membrane)
Buzzing/rattling sound (loose component)
The fix: Speaker replacement. Speakers are modular components that unplug from motherboard, making replacement straightforward.
💰 Typical cost:
Loudspeaker replacement: R300-R600
Earpiece speaker replacement: R300-R550
Both speakers: R550-R950 (combo discount)
Data safe? Yes, 100% – speakers are separate components
What it is: Your phone typically has 3-4 microphones in different locations:
Primary mic (bottom): Main mic for calls, voice recordings
Secondary mic (top): Noise cancellation during calls
Back mic (near camera): For video recording audio
Front mic (near earpiece): Some models have additional front mic
How microphones work: Sound waves hit membrane → Membrane vibrates → Converted to electrical signal → Processed by audio codec chip
How microphones fail:
Water damage – Most common cause; water damages sensitive membrane
Dust/lint blocking mic hole – Tiny hole (1mm) easily blocked
Physical impact – Dropping phone damages delicate membrane
Corrosion – Moisture causes rust on contacts
Manufacturing defect – Some phone models have known mic issues (especially certain Samsung, Huawei models)
Symptoms by mic type:
Primary mic dead: People can't hear you during calls; voice notes don't work
Secondary mic dead: People hear background noise during calls (noise cancellation broken)
Back mic dead: Videos have no sound; front camera videos work fine
All mics dead: Suggests audio codec IC failure on motherboard (more serious)
The fix: Microphone replacement. Like speakers, mics are modular components on flex cables.
💰 Typical cost:
Single microphone: R300-R550
Multiple mics: R600-R900
Microphone flex cable assembly: R400-R700
Data safe? Yes, 100%
What it is: The Audio Codec IC is a chip on your phone's motherboard that:
Converts digital audio (MP3, video soundtracks) to analog signals for speakers
Converts analog microphone input to digital data for recording
Routes audio to correct output (speaker vs earpiece vs headphones)
Controls volume levels and audio processing
Common names: Cirrus Logic codec, Qualcomm WCD codec, Realtek audio IC
How it fails:
Water damage causing short circuit (most common)
Physical impact from drops (micro-fractures in solder joints)
Electrical surge from faulty charger
Manufacturing defect (some phone models have known audio IC issues)
Overheating from prolonged high-volume use
Symptoms of audio IC failure:
All audio dead – No speaker, no earpiece, no mic, no headphone output
Intermittent audio – Works sometimes, dead other times
Distortion on all outputs – Speaker, earpiece, and headphone all crackling
"No audio device found" error in settings
Headphone mode stuck even when nothing plugged in
The fix: Micro-soldering audio codec IC replacement. This is advanced board-level repair:
Requires professional hot air rework station
Stereo microscope work (chip is 4-6mm in size)
Precise temperature control (350-380°C)
BGA reballing (chip has 60-100 tiny solder balls underneath)
Not all shops can do this – requires expert-level soldering skills.
💰 Typical cost: R850-R1,600 depending on phone model | Data safe? Yes, data on separate storage chip
What it is: The 3.5mm headphone jack (on phones that still have one) is a mechanical switch:
When you plug in headphones, metal pins make contact
Contact tells phone to route audio to headphones instead of speaker
When unplugged, spring-loaded pins return to default position
How it fails:
Debris/lint packed inside – Blocks headphone plug from fully inserting
Bent or broken pins – From forcing plug in wrong way or yanking sideways
Corrosion – Moisture causes rust on contacts
Worn spring contacts – After hundreds of plug/unplug cycles
Water damage – Liquid seeps in, damages internal components
Symptoms:
Headphones not recognized
Intermittent audio (works at certain angles)
"Headphone mode stuck" – Phone thinks headphones plugged in when they're not (audio only plays through headphones that aren't there)
One earphone side works, other doesn't
The fix:
Minor: Deep cleaning with compressed air + isopropyl alcohol (R150-R250)
Major: Headphone jack flex cable replacement (R400-R700)
💰 Typical cost: R150-R700 | Data safe? Yes, 100%
What it is: Water/liquid damage specifically affecting audio system:
Liquid enters speaker/mic chambers
Corrosion forms on audio flex cables
Water shorts audio circuits on motherboard
Moisture damages speaker/mic membranes
How liquid enters:
Through speaker mesh (easiest entry point)
Through microphone holes (tiny openings)
Through headphone jack (on older phones)
Through charging port (can affect audio circuits nearby)
Progressive damage timeline:
0-24 hours: Muffled sound, reduced volume (moisture blocking membranes)
24-72 hours: Intermittent audio (corrosion starting on contacts)
3-7 days: Crackling, distortion (corrosion spreading)
1-2 weeks: Complete audio failure (corrosion damages circuits)
Why immediate treatment matters: Even if audio "still works" after water exposure, corrosion is actively spreading and will cause failure within days/weeks.
The fix:
Ultrasonic cleaning to remove liquid/contaminants
Isopropyl alcohol flush of affected areas
Corrosion removal under microscope
Component replacement if damaged (speaker, mic, audio IC)
💰 Typical cost: R600-R2,200 depending on damage extent | Success rate: 75% if treated within 24hrs, drops to 45% after 72hrs
1. Clean Speaker & Microphone Holes (Gently!)
You'll need: Soft-bristled toothbrush (dry), wooden toothpick
Speaker cleaning:
Locate speaker grilles (bottom edge, top earpiece)
Gently brush across grilles with dry toothbrush
Use toothpick to dislodge visible debris (don't push deep)
Test audio after cleaning
Microphone cleaning:
Find mic hole (usually bottom edge, tiny pinhole)
Gently scrape around hole opening with toothpick
Blow across hole to dislodge debris
Test voice recording
Why this works: 40% of "low volume" or "muffled mic" issues are just blocked holes.
⏱️ Takes: 5 minutes | Success rate: 35-40% for partial blockage cases
2. Remove Phone Case & Screen Protector
Some cases have poor cutouts that:
Block speaker grilles (reduces volume by 30-50%)
Cover microphone holes (makes you sound muffled)
Test without case:
Remove case completely
Make test call or record voice note
If audio improves dramatically → case is the problem
3. Check Volume Settings & Audio Balance
For low volume issues:
iPhone: Settings > Sounds & Haptics > Ringer and Alerts (drag slider to max)
Android: Settings > Sounds > Volume (check Media, Call, Ring volumes)
For one-sided audio (stereo issues):
iPhone: Settings > Accessibility > Audio/Visual > Balance (should be centered)
Android: Settings > Accessibility > Hearing > Audio Balance (should be centered)
4. Restart Your Phone (Clears Software Glitches)
Simple restart fixes:
Audio routing errors (sound going to wrong output)
Volume control bugs
Bluetooth conflicts (phone stuck routing audio to disconnected Bluetooth device)
How to restart:
iPhone 8+: Press Volume Up, press Volume Down, hold Side button until Apple logo
Android: Hold Power button, tap Restart
5. Check for Water Damage Indicators
iPhone: Look in SIM card tray – red/pink dot means water damage
Android: Often have indicator near SIM tray or inside USB port
If indicator is red, audio issues are likely water-related → bring to us immediately.
6. Test in Safe Mode (Android Only – Checks for App Conflicts)
Boot to Safe Mode:
Hold Power button
Long-press "Power Off" option
Tap "OK" to reboot to Safe Mode
In Safe Mode:
Test audio (speaker, mic, calls)
If audio works perfectly → a third-party app is causing problems (uninstall recent apps)
If audio still broken → hardware issue
🚫 DO NOT Blow into Speakers/Mic Holes with Your Mouth
Why: Your breath contains moisture. Blowing moisture into electronics causes:
Corrosion on internal components
Liquid damage to membranes
Short circuits
Use compressed air only (or blow gently across hole, not into it).
🚫 DO NOT Insert Metal Objects into Speaker Grilles or Mic Holes
Never use: Needles, paperclips, SIM ejector tool, tweezers
Why:
Punctures speaker membrane (instant permanent damage)
Damages microphone diaphragm
Can short circuit internal connections
Use wooden toothpicks only.
🚫 DO NOT Play Maximum Volume for Extended Periods
Why: Speakers have physical limits. Playing max volume (especially bass-heavy music) for hours:
Tears speaker membrane
Separates voice coil from cone
Causes permanent distortion
Especially damaging: Max volume + bass boost + small enclosed space (bathroom, car)
Keep volume at 70-80% max for speaker longevity.
🚫 DO NOT Submerge Phone to "Clean Speakers" (Even if Waterproof)
Why: Even IP67/IP68 rated phones have limits:
Water resistance degrades over time (seals wear out)
Soap, chlorine, salt water bypass ratings
Submerging forces water past speaker membranes into phone interior
"Waterproof" means survive accidental splashes, not intentional submersion.
🚫 DO NOT Use Rice for Water-Damaged Audio
Why rice doesn't work:
Doesn't actively pull water out of phone
Dust/starch from rice enters phone through speaker/mic holes
Delays proper treatment (corrosion continues spreading)
If phone got wet:
Power off immediately
Don't try to charge or turn on
Bring to us within 24 hours for proper ultrasonic cleaning
🚫 DO NOT Ignore "Headphone Mode Stuck" – It Gets Worse
Why: When phone thinks headphones are plugged in (but they're not):
All audio routes to headphone jack (you hear nothing from speaker)
This usually means moisture/corrosion in headphone jack
Corrosion spreads to nearby circuits if not treated
Temporary workaround: Plug and unplug headphones 10-15 times (sometimes clears stuck switch)
Permanent fix: Headphone jack replacement (R400-R700)

Schedule your repair. Choose preferred time slot.
A: Sometimes YES – if the problem is:
Blocked speaker grilles (cleaning solves it)
Software glitch (restart/reset solves it)
Loose internal connector (reseating solves it)
Corrosion on contacts (cleaning solves it)
We always check these first. If cleaning/reseating fixes it, you pay only diagnostic fee (R150-R250) instead of full component replacement.
Honest diagnosis saves you money.
A: That's a microphone problem (specifically your primary mic at the bottom of the phone).
Speaker = what YOU hear
Microphone = what OTHERS hear
Most likely causes:
Blocked mic hole (clean with toothpick – R150)
Water-damaged mic (needs replacement – R350-R550)
Faulty phone case covering mic hole (free fix – remove case)
Bring it in for free mic test – we'll pinpoint exact issue.
A: NO – it will get WORSE. Here's why:
What's happening inside:
Water/moisture trapped in speaker chamber
Corrosion starting on electrical contacts
Speaker membrane absorbing moisture (swells, can't vibrate properly)
Timeline if you don't get it cleaned:
Day 1-2: Muffled, reduced volume (you're here now)
Day 3-5: Crackling, distortion
Week 1-2: Complete speaker failure
Week 2-4: Corrosion spreads to motherboard (expensive repair)
The fix: Professional ultrasonic cleaning + speaker replacement if needed (R600-R1,200)
Act within 24-48 hours for best results.
A: YES, absolutely. iPhone X and newer models use dual stereo speakers:
Bottom loudspeaker (one channel)
Top earpiece (acts as second stereo channel)
If one side is silent:
One speaker failed (needs replacement R300-R600)
Audio routing issue (software reset might fix)
Audio codec IC partially failed (R1,200-R1,800 repair)
Bring it in for free diagnosis – we'll identify which component failed.
A: Often YES. We specialize in board-level audio repairs that many shops can't do:
Audio codec IC replacement (requires micro-soldering)
Corroded circuit trace repair (requires microscope work)
Multi-point corrosion cleaning (ultrasonic bath + manual cleaning)
We've successfully recovered audio on phones declared "dead" by:
Official manufacturer service centers
Other independent repair shops
"Fast repair" mall kiosks
Bring it in for second opinion – free diagnosis will tell you if recovery is possible.
A: Try this simple test:
Software test:
Restart phone (hold power button)
Test audio after restart
If audio works → was software glitch
If still broken → hardware issue
Hardware test:
Play music/video
Cover bottom speaker with finger
If you feel vibration but no sound → speaker membrane damaged (hardware)
If no vibration at all → complete hardware failure or audio IC issue
Still unsure? Bring it in – our diagnostic test identifies exact cause in 10 minutes (free).
A: Usually YES, but not always. Depends on cause:
Speaker replacement fixes:
Blown speaker membrane (95% success)
Water-damaged speaker (90% success)
Torn speaker cone (95% success)
Speaker replacement WON'T fix:
Audio codec IC failure (needs IC replacement instead)
Corrupted audio drivers (needs software reflash)
Audio amplifier chip damage (needs micro-soldering)
We diagnose first to ensure we're fixing the right component. No guesswork.
A: YES. This happens when:
Mechanical switch stuck inside headphone jack (debris, corrosion)
Moisture/liquid caused contacts to corrode and stay closed
Bent pin inside jack won't return to default position
Fixes:
Temporary workaround: Plug/unplug headphones 10-20 times rapidly (sometimes unsticks it)
Cleaning: Professional cleaning with isopropyl alcohol + compressed air (R150-R250)
Replacement: Headphone jack flex cable replacement if cleaning doesn't work (R400-R700)
Success rate: 92% with cleaning or replacement.
A: NO – 100% data safe. Audio components (speakers, microphones, headphone jack, even audio IC) are completely separate from your phone's storage.
Your data lives on:
NAND flash memory chip (separate from audio system)
SSD storage (on modern phones)
Even if we replace every audio component, your photos, contacts, messages, and apps remain untouched.

Keep volume at 70-80% maximum – Max volume tears speaker membranes over time
Avoid bass-heavy music at max volume – Bass requires more speaker movement (more stress)
Don't play music in dusty/dirty environments – Dust enters speaker grilles and blocks membranes
Use external Bluetooth speakers for parties/loud environments instead of phone speaker
Clean speaker grilles monthly – Soft toothbrush removes dust buildup
Clean mic holes every 2-3 months – Wooden toothpick + gentle scraping
Keep phone in clean pockets – Front pocket collects less lint than back pocket
Remove phone from pocket before sitting – Pressure packs debris into mic holes
Use quality phone cases with proper mic cutouts – Cheap cases block mic holes
Avoid speaking directly into mic hole when recording (1-2 inches away is optimal)
Never use phone in bathroom during shower – Steam = water vapor that enters speakers
Wipe phone dry immediately if exposed to rain/splashes – Don't wait "to see if it dries"
Don't charge phone near water – Accidents happen; keep charging station away from sinks/drinks
If phone gets wet, bring to us within 24 hours – Corrosion prevention is critical
Don't trust "waterproof" ratings after 1+ year – Seals degrade over time
Insert plugs straight, never at angles – Angles bend internal pins
Don't yank headphones out – Pull gently and straight
Keep jack covered when not in use – Dust plug prevents debris entry (R20 at most stores)
Clean jack every 3-6 months – Wooden toothpick + gentle scraping
Avoid cheap headphones – Poor quality plugs damage jack over time
What you need: Soft cloth, bowl of uncooked rice (or better: silica gel packets)
Steps:
Power off phone completely
Pat dry all external surfaces with cloth
Place phone in bowl of rice/silica gel for 4-6 hours (speaker facing down)
After 6 hours, remove and test speaker
If still muffled after 12 hours → professional cleaning needed immediately
Success rate: 30-40% for light moisture
⚠️ Warning: This is temporary emergency fix only. Water damage needs professional treatment within 24 hours.
What you need: Wooden toothpick, flashlight, soft toothbrush
Steps:
Locate microphone hole (usually bottom edge, tiny pinhole)
Shine flashlight at hole – you'll see packed debris
Gently scrape around hole opening with toothpick (don't push deep inside)
Brush across hole with dry toothbrush
Test with voice recording app
Success rate: 40% for blocked mic issues
Time: 5 minutes
When to try: Speaker works sometimes but not always; audio randomly switches outputs
iPhone 8 and newer:
Press and release Volume Up button
Press and release Volume Down button
Hold Side button until Apple logo appears
Android (most models):
Hold Power button for 30 seconds, or
Hold Power + Volume Down for 10 seconds
Success rate: 15% for software-related audio glitches
When to try: No sound from phone speaker, but phone isn't in silent mode
Steps:
Open Settings > Bluetooth
Check if any device is "Connected"
Tap device name > "Forget This Device" or "Disconnect"
Turn Bluetooth OFF completely
Test speaker
Why this works: Sometimes phone stays connected to Bluetooth speaker/headphones even when they're off or out of range. Audio routes to them = you hear nothing from phone.
Success rate: 10% of "no sound" cases
When to try: No ringtone, no notification sounds, but media audio works
iPhone:
Check for moon icon in status bar (Do Not Disturb)
Swipe down from top-right (Control Center)

Sometimes additional speakers for true stereo (rare)
All modern smartphones have 2-4 mics:
Primary mic (bottom) – Main mic for calls and recordings
Secondary mic (top) – Noise cancellation (filters background noise during calls)
Back mic (near camera) – Captures audio for video recordings
Front mic (near screen) – Some models have additional front-facing mic
How noise cancellation works:
Primary mic captures your voice + background noise
Secondary mic captures mostly background noise
Phone's processor subtracts secondary from primary = clearer voice
Why calls are clear in noisy environments – dual-mic noise cancellation!

Truth: This is TERRIBLE advice found on YouTube. It pushes water DEEPER into your phone and causes more damage. Never do this.
Proper water removal: Professional ultrasonic cleaning only.
Truth: Your breath contains moisture. Blowing moisture into electronics causes corrosion. Use compressed air (or blow across, not into).
Truth: Crackling can also be caused by:
Debris on speaker membrane (cleaning fixes it)
Loose connection (reseating fixes it)
Audio IC failure (needs chip replacement)
Software glitch (reset fixes it)
Diagnosis needed before assuming replacement required.
Truth: Audio ICs have separate channels. One channel can fail while other works. This actually confirms IC failure (since speakers themselves are separate components).
Truth: Microphones are modular components easily replaced. Even water-damaged mics are fixable 90% of the time with cleaning or replacement.
