Reolink Audio Not Working: Quick Fixes for UK Homeowners

If your Reolink camera or doorbell isn’t capturing or playing back audio, start with these immediate checks. These solutions address the most common causes of audio failure without requiring router changes or advanced diagnostics.

Power Cycle Your Device

Unplug your Reolink device from its power source (or remove the battery if it’s battery-powered) for 30 seconds. Reconnect it and wait 1 minute before testing audio again. This resets the device’s internal circuitry and can resolve temporary audio glitches.

Restart the Reolink App

Close the Reolink App completely and reopen it. On iOS, double-press the home button and swipe up to close the app. On Android, swipe up from the bottom of the screen and hold, then swipe the app away. A fresh app launch can re-establish audio connections lost during app updates or crashes.

Check LED Status for Battery Issues

For battery-powered models like the Argus Track, look for a red LED on the device. A red light indicates the battery is low and may have disabled audio features. Charge the battery fully via the Reolink App before testing audio again.

Verify Power Cable and Transformer

For wired models like the RLC-1212A, ensure the power cable is securely connected to both the camera and the transformer. Check the transformer’s voltage at the junction box — it must supply 16-24V AC. Use a multimeter to confirm this; incorrect voltage can cause audio failures even if the camera appears online.

Confirm App Login and Permissions

Open the Reolink App and ensure you’re logged in with the correct account. Navigate to SettingsAccount to verify your login. Additionally, check that the app has microphone and speaker permissions enabled in your device’s settings. On iOS, go to SettingsReolink AppMicrophone and Bluetooth. On Android, go to SettingsAppsReolinkPermissions.

Step-by-Step Audio Troubleshooting

Check Your Reolink Device’s Wi-Fi Band Settings

Ensure 2.4GHz Mode is Enabled

Reolink devices often struggle with audio transmission on 5GHz networks due to higher frequency interference. In the Reolink App, go to Device SettingsWi-Fi and ensure 2.4GHz mode is selected. For models like the Argus Track (dual-band), this setting is critical for stable audio performance.

For Reolink Video Doorbell (PoE)

If your doorbell is on a 5GHz network, switch it to 2.4GHz. The PoE model only supports Wi-Fi (no Ethernet), so ensure it’s connected to the correct band. If you’re unsure which band your router uses, check the Wi-Fi settings on your smartphone — most routers label 2.4GHz and 5GHz networks separately.

Use the Reolink App’s Device Health Feature

Check Signal Strength (RSSI)

Open the Reolink App and navigate to Device HealthSignal Strength. Look for an RSSI value above -70dBm. Values below this indicate weak signal strength, which can cause audio dropouts or complete failure. If the signal is weak, move the camera closer to the router or use a Wi-Fi extender.

Test Push Notifications

In the Reolink App, go to Device SettingsPush Notifications and select Test. This sends a test alert with audio playback to confirm your device is transmitting sound correctly. If the test fails, the issue may be with the audio codec or a hardware fault.

Update Your Reolink Firmware

Check for Firmware Updates

Firmware updates often resolve audio compatibility issues. In the Reolink App, go to Device InfoFirmware Version and compare it with the latest version on Reolink’s support site. If an update is available, navigate to SettingsFirmware Update and follow the on-screen instructions. Ensure your device remains connected to power during the update to avoid corruption.

For RLC-1212A and Argus Track

These models may require a factory reset before applying a firmware update. For the Argus Track, press and hold the Reset button for more than 5 seconds. For the RLC-1212A, hold the Reset button for 10 seconds. After resetting, reconnect the device to your network and proceed with the firmware update.

Model-Specific Audio Reset Procedures

Argus Track (Battery-Powered)

If audio issues persist, perform a full factory reset. Press and hold the Reset button for more than 5 seconds until the LED flashes rapidly. This clears all settings and allows the device to re-pair with your network. After resetting, enable 2.4GHz mode in the Reolink App and ensure the battery is charged to at least 20%.

Reolink Video Doorbell (Wi-Fi Model)

For Wi-Fi models, use a paperclip to press the reset button until a short music tone plays. This resets the device to factory defaults. Reconnect it to your network and ensure 2.4GHz mode is enabled. If the doorbell is on a 5GHz network, switch bands to improve audio stability.

RLC-1212A (PoE Model)

Hold the Reset button for 10 seconds to restore factory settings. This is necessary for PoE models that may have lost audio functionality due to incorrect network settings. After resetting, ensure the transformer voltage is between 16-24V AC and that the device is connected to a 2.4GHz Wi-Fi network.

Port Forwarding and Network Configuration

Check Port Forwarding Settings

If your Reolink camera is on a private network, ensure the necessary ports are forwarded. Common ports for Reolink devices include 80 (HTTP), 443 (HTTPS), 554 (RTSP), and 8000 (Custom). Access your router’s admin panel (usually via 192.168.1.1 or 192.168.0.1) and add these ports to the Port Forwarding section. Ensure the destination IP is set to your Reolink camera’s local IP address.

Disable Router Firewalls

Some routers block traffic from Reolink devices due to firewall settings. In your router’s Advanced Settings, disable any firewall rules that apply to Reolink IP addresses or RTSP protocol. This is especially important for models like the RLC-1212A that rely on RTSP streaming for audio transmission.

Advanced Diagnostics and Support

Access Reolink Device Logs

Use the Reolink App’s Diagnostic Tools

Open the Reolink App and navigate to Device InfoLogs. Look for any error messages related to audio transmission or codec failures. These logs can help identify if the issue is software-related (e.g. incompatible firmware) or hardware-related (e.g. faulty microphone). If the logs are unclear, export them to your device and share them with Reolink support via their website.

For RLC-1212A and Argus Track

These models may require hardware diagnostics. For the Argus Track, use the Push Notification Test in the app to confirm the microphone is functioning. If the test fails, the microphone may be damaged. For the RLC-1212A, use a multimeter to check if the microphone port is receiving power. A lack of power indicates a hardware fault.
