Eufy Security Camera Sound Not Working? Fix It Fast

You’re checking your Eufy security camera to hear your child cry, a knock at the door, or suspicious noise—only to find dead silence. The video works perfectly, motion alerts trigger, and older recordings still have sound. But in live view and new clips, your Eufy security camera sound is not working. You’re not alone. This widespread issue has affected Eufy Indoor Cam 2K, Pan & Tilt, E220, C120, and doorbell models since 2023, with no official public fix as of 2025.

Despite hundreds of user reports across Reddit, Eufy forums, and support channels, Eufy has not acknowledged a systemic flaw or released a universal patch. Firmware updates like 2.2.0.0 and 2.3.1.6 are frequently blamed, and HomeKit integration often makes things worse. Customer support typically responds with automated replies or denies the issue exists—especially for out-of-warranty units.

This guide gives you a complete, step-by-step strategy to fix the Eufy security camera sound not working problem. From hidden factory film to firmware rollbacks and HomeKit conflicts, we cover every proven solution based on real user experiences and verified troubleshooting data.

Confirm What Type of Audio Failure You’re Facing

Before diving into fixes, identify the exact nature of your audio issue. The solution depends on whether the problem is in live view, recordings, or two-way talk.

Live Feed Silent But Recordings Have Sound?

If you can hear audio in old clips but new recordings or live view are silent, the microphone may be disabled in settings or frozen due to a firmware glitch. This is common after automatic updates.

No Sound in Any Recordings?

If all recent recordings lack audio, check if the microphone is turned off in the app. Also consider firmware corruption or hardware failure—especially if multiple cameras fail simultaneously.

Two-Way Talk Works One Way?

If you can speak through the camera but can’t hear responses (or vice versa), the mic or speaker is partially disabled. Try toggling both audio settings off and on.

Static, Popping, or Wind-Like Noise?

This could indicate power instability, interference, or firmware corruption. Try replacing the power adapter and rebooting the camera.

🔍 Check the audio waveform: In the Eufy app, open a recent motion clip. If the timeline shows no audio wave, the mic is likely disabled or malfunctioning.

Remove Factory Protective Film from the Microphone

One of the most overlooked causes: clear plastic film covering the microphone at the factory.

How to Locate and Remove It

The microphone is a tiny pinhole, usually near the lens or on the bottom edge.
Shine a flashlight at an angle. A faint shimmer indicates protective film.
Use tweezers or a fingernail to gently peel it off.

✅ Real user result: “I wasted time troubleshooting settings until I realized the plastic covers the mic too. Removed it—sound came back instantly.” – TearDesigner948

This fix has worked for numerous users who missed the nearly invisible cover during setup. Don’t assume your camera was pre-cleaned—always inspect.

Enable and Re-enable the Microphone in the Eufy App

Even if the mic appears enabled, a firmware glitch may have disabled it silently.

Step-by-Step: Turn Microphone On

Open the Eufy app.
Tap your affected camera.
Go to Settings > Audio Settings.
Ensure Microphone is toggled ON.
Also check Speaker if two-way talk is failing.

❗ Critical mistake: Just because recordings exist doesn’t mean audio is active. Silent recordings mean the mic is off.

Perform a Soft Reset of the Mic

Toggle Microphone OFF.
Wait 10 seconds.
Toggle Microphone ON again.

✅ User success: “After disabling and re-enabling the mic, sound returned better than before.” – bgreenstone

This simple reset reinitializes the audio driver and has fixed the issue for many users after problematic updates.

Restart the Camera and Eufy App

A quick reboot clears temporary software hangs that can mute audio.

Power Cycle the Camera

Unplug the camera for 30 seconds.
Plug it back in.
Wait for the LED to stabilize (about 1–2 minutes).
Reopen the Eufy app and test audio.

Force-Close and Reopen the App

iOS: Swipe up from bottom, swipe app away, relaunch.
Android: Go to Settings > Apps > Eufy > Force Stop, then reopen.

⏱️ Total time: Under 2 minutes. Low effort, high chance of success.

Update or Rollback Firmware

Firmware is the most likely culprit. Versions 2.2.0.0 and 2.3.1.6 are widely reported to break audio.

Check Your Firmware Version

In the Eufy app, go to Device Settings > Device Info.
Note the Firmware Version.

High-Risk Versions:

2.2.0.0
2.3.1.6
2.1.9.7, 2.1.9.9

Many users report audio loss immediately after these updates.

Install Latest Firmware (If Available)

Go to Device Info > Check for Update.
Install if an update is pending.

⚠️ Warning: Updating may not help—and could make things worse if the latest version has the bug.

Request Firmware 2.1.8.4 from Eufy Support

This older version has restored audio for many users.

Contact Eufy via live chat or email (support@eufy.com).
Ask: “Can you push firmware 2.1.8.4 to my camera? I lost audio after the last update.”
Some support agents will manually apply it.

✅ User result: “Eufy support applied 2.1.8.4 manually. After re-enabling mic, sound came back.” – BopNiblets

Not all users get this version—depends on agent and region.

Remove HomeKit Integration Causing Audio Conflict

Apple HomeKit is a major trigger for Eufy security camera sound not working.

Audio Works in HomeKit But Not Eufy App?

This is a known conflict:
– Adding the camera to HomeKit can disable the mic in the Eufy app.
– Re-adding it may permanently break audio in Eufy.

Fix: Remove from HomeKit

Open Apple Home app.
Long-press camera > Remove Accessory.
Confirm deletion.
Reboot the camera.
Test audio in the Eufy app only.

✅ User result: “After removing from HomeKit and re-adding in Eufy app, sound was loud and clear. Adding back to HomeKit broke it again.” – FilthyCriminal66

Workaround: Use Eufy App as Primary

If you need both apps:
– Set up the camera only in Eufy app first.
– Test audio.
– Then add to HomeKit without re-adding in Eufy.
– Monitor for audio drop after updates.

⚠️ Risk: Future firmware updates may still break sync.

Factory Reset the Camera

If other fixes fail, reset the camera to factory defaults.

How to Reset

Locate the Sync button (small pinhole).
Press and hold for 10 seconds.
Release when LED flashes red or you hear a beep.
Camera will reboot and reset.

Re-add the Camera

In the Eufy app, go to Add Device.
Follow setup steps.
Verify microphone is enabled during setup.
Test audio immediately.

⏱️ Time required: 5–10 minutes.
✅ Success rate: High for isolated failures.

❌ Note: If multiple cameras lose audio at once, it’s likely not hardware—focus on firmware or network.

Replace the Power Adapter

Weak power can destabilize audio components.

Use a 5V 2A Power Supply

Try a USB fast charger (5V 2A) instead of the original adapter.
Ensure the cable is undamaged and fully plugged in.

✅ User result: “Replaced original adapter with 5V 2A unit—audio came back.” – Tall_Tarmarind

🔍 Why it works: Underpowered units may not supply enough current for the microphone array.

Fix Phone-Level Audio Settings

The problem might be your phone, not the camera.

Android: Check Notification Sound

Go to Settings > Apps > Eufy > Notifications.
Tap Eufy Motion Alerts.
Ensure Sound is enabled (not set to “None”).
Disable Battery Optimization for Eufy app.

iOS: Update to Latest Version

Some users fixed audio by updating to iOS 17.1.1.
Go to Settings > General > Software Update.

✅ User result: “No firmware updates, but after iOS update, sound works in both apps.” – merlin_zaraza

❗ No Android OS fix confirmed, but clearing app cache may help.

Clear App Cache (Android)

Settings > Apps > Eufy > Storage.
Tap Clear Cache.
Reopen app and test.

Test on Another Device

Isolate whether the issue is camera-side or playback-side.

Try On:

Another phone
Tablet
Computer (via Eufy website or HomeBase)

If sound works on one device but not another:
– Problem is device-specific.
– Focus on reinstalling the app or adjusting OS settings.

🔁 User experience: “Uninstalled and reinstalled app—fixed for one day, then failed again.” – Dav2031
→ Suggests temporary software glitch.

What to Say

“My Eufy camera has no audio in live feed or recordings. I’ve tried resets, re-enabling mic, and checking settings. Multiple users report this after firmware 2.3.1.6. Can you push firmware 2.1.8.4 manually?”

What to Expect

Automated replies: “We’re reviewing with product team…”
Denial of issue: “No known defects”
Warranty denial: Units over 1–3 years often denied help

❌ User frustration: “Told warranty expired. No solution. That’s a shame for a 3-year-old camera.” – Valden7

Escalate

Reference Reddit threads or Eufy forums.
Mention multiple cameras failed.
Request replacement unit if under warranty.

Long-Term Reliability and Alternatives

Is This a Design Flaw?

Users report:
– Power supplies failing
– Microphones degrading over time
– Audio disappearing across 7+ cameras

“They are all junk. Power supplies go bad. Also have no sound issues in multiple cameras because that also fails over time.” – gerard_k_

This pattern suggests component or firmware flaws, not random failure.

Brand Trust Erosion

No transparency
Delayed fixes
Poor support for older units

“Watching my baby cry with no sound. Eufy’s reputation going to crap.” – DesignerWarning2929

For baby monitoring or safety-critical use, consider switching brands.

Reliable Alternatives

Google Nest Cam: Strong firmware, reliable audio
Arlo Pro 5: Consistent two-way talk, better support
Ring Indoor Cam: Alexa integration, stable audio

Final Checklist: Fix Eufy Camera No Sound
