Arlo Audio Not Working? Try These Brand-Specific Fixes

Audio failure on your Arlo camera can be frustrating, but most issues are resolvable with targeted troubleshooting. Common causes include firmware incompatibility, incorrect app permissions, or hardware degradation. By following brand-specific steps such as using the Wi-Fi Troubleshooting Tool in the Arlo Secure app or verifying Battery Health metrics, you can often resolve the issue without professional help. If initial checks fail, proceed to advanced diagnostics or contact Arlo support directly for further assistance.

Quick Fixes for Arlo Audio Issues

These 30-second checks address the most common causes of audio failure:

  • Power cycle your camera: For battery models, remove the battery for 30 seconds then reinsert. For wired models, unplug the transformer for 10 seconds.
  • Restart the Arlo Secure app: Close the app completely, then reopen it and check if audio is restored.
  • Verify LED status: A solid green LED indicates proper power. Blinking amber may signal low battery or connectivity issues.
  • Check power cable/battery: Ensure the battery is fully charged (minimum 20% for battery models) and the power cable is securely connected.
  • Confirm app login: Log out of the Arlo Secure app and log back in to refresh the connection.

Step-by-Step Troubleshooting for Arlo Audio Issues

Check Your Arlo Camera's Wi-Fi Band Settings

Arlo cameras use 2.4GHz or dual-band (2.4GHz + 5GHz) Wi-Fi. For models like the Arlo Essential 2K, which only support 2.4GHz, ensure your router is broadcasting on this band:

  • Open the Arlo Secure app > Device Health > Wi-Fi Settings
  • Select 2.4GHz mode exclusively
  • Disable 5GHz band if enabled If your camera supports dual-band (e.g. Arlo Pro 6), use the Wi-Fi Troubleshooting Tool in the app to identify signal interference. The tool will recommend switching to 2.4GHz if interference is detected.

Update Your Arlo Camera's Firmware

Outdated firmware can cause audio compatibility issues. To update:

  1. Open the Arlo Secure app > Settings > Firmware Updates
  2. If an update is available, tap Update Now
  3. Wait for the camera to reboot and reconnect Ensure your camera is within 10-15 feet of your router during the update process. If the update fails, repeat the power cycle steps from the Quick Fixes section.

Use the Arlo Secure App's Signal Strength Meter

Weak signal strength can degrade audio quality or prevent recording:

  • Open the Arlo Secure app > Device Health > Signal Strength
  • Check the RSSI (Received Signal Strength Indicator) value
  • Ideal signal strength is -60dBm or higher If the signal is weak (-70dBm or lower), move the camera closer to the router or install a Wi-Fi extender compatible with Arlo's 802.11b/g/n standards. For UK homes with solid brick walls, consider using a Mesh Wi-Fi system to improve coverage.

Verify Audio Permissions in the Arlo Secure App

Audio issues can occur if app permissions are disabled:

  • On iOS: Go to Settings > Arlo Secure > Enable Microphone and Camera permissions
  • On Android: Go to Settings > Apps > Arlo Secure > Permissions > Enable Microphone and Camera If permissions are already enabled, try re-pairing the camera via the app:
  1. Open the Arlo Secure app > Devices > Add Device
  2. Follow the on-screen instructions to re-pair
  3. Ensure you select the correct Wi-Fi band during setup

Use the Arlo Secure App's Audio Test Feature

Some Arlo models include an Audio Test feature to verify microphone/speaker functionality:

  • Open the Arlo Secure app > Device Health > Audio Test
  • Speak into the camera's microphone and check if the test audio is captured
  • Play a test tone through the speaker and ensure it is audible If the test fails, the issue may be hardware-related. Proceed to the Advanced Diagnostics section for further steps.

Advanced Diagnostics for Persistent Arlo Audio Issues

Factory Reset an Arlo Camera

If basic troubleshooting fails, perform a factory reset:

  • Arlo Pro 6: Press and hold the Sync button on the camera for 10 seconds until the LED blinks blue
  • Arlo Essential 2K: Press and hold the Pairing button on the top for 15-30 seconds until the LED turns solid blue then blinks amber After resetting, re-pair the camera via the Arlo Secure app as described in the Step-by-Step section. If the issue persists, proceed to the next step.

Export Diagnostic Logs for Arlo Support

If the camera still fails to capture or play back audio, export diagnostic logs:

  1. Open the Arlo Secure app > Settings > Support > Export Logs
  2. Save the logs to your device and email them to Arlo support at https://www.arlo.com/en_gb/support Include details about the audio issue (e.g. "no sound captured during live view"). Arlo engineers will use these logs to identify firmware or hardware-specific issues.

Contact Arlo Support for Hardware Faults

If all troubleshooting steps fail and the camera is over 3-5 years old (battery models) or shows degraded performance in the Battery Health Monitor, contact Arlo support for replacement options. UK consumers have up to 6 years under the Consumer Rights Act 2015 to claim faulty goods.

Understanding the Root Causes of Arlo Audio Issues

Audio failure on Arlo cameras can stem from several factors, including:

  • Firmware incompatibility: Outdated firmware may not support modern audio codecs used by your router or ISP
  • Signal interference: Solid brick walls (common in UK pre-1920s terraced houses) can degrade 2.4GHz signal strength by 10-15dB per wall
  • Battery degradation: Battery-powered models (e.g. Arlo Essential 2K) may fail to capture audio if the battery is below 20%
  • Hardware faults: Physical damage to the microphone/speaker grid or internal components
  • App configuration errors: Incorrect permissions or settings in the Arlo Secure app

Preventing Future Arlo Audio Issues

Regular maintenance can prevent recurring audio problems:

  • Update firmware monthly: Check for updates in the Arlo Secure app under Settings > Firmware Updates
  • Monitor battery health: Use the Battery Health Monitor in the app to track performance degradation
  • Use the Wi-Fi Troubleshooting Tool: Run the tool weekly to identify signal interference
  • Avoid Foil-backed insulation: These materials can block Wi-Fi signals entirely; consult a professional if retrofitting

Full disclosure: we built scOS to address exactly this—the frustration of cameras that depend on Wi-Fi to function. scOS uses permanently powered cameras connected via ethernet, eliminating signal interference and battery degradation risks.

When to Consider Replacing Your Arlo Camera

Audio issues may indicate the end of a camera's lifespan:

  • Battery models: 3-5 years typical. Replace if the battery holds less than 20% charge after 300-500 cycles
  • Wired models: 5-8 years typical. Replace if firmware updates are no longer available
  • Professional installation: Costs £150-£300 per camera for complex setups
  • UK consumer rights: You have up to 6 years to claim faulty goods under the Consumer Rights Act 2015
