In this article, we will discuss the possible causes for “Reolink two-way audio not working” and provide some effective solutions to fix the issue.

Reolink Two-way Audio Not Working: Causes

Here are some of the most suspected causes of ‘Reolink Audio Not Working’:

1. Volume Slider is not Up

The reason your Reolink two-way Audio is not working might be as simple as not turning your volume up. Firstly, the volume at the bottom of the Live View page may be done or muted.

Also, the volume of computer or phone may not be turned up to maximum. Do well to double-check.

2. Audio Record Is Not Enabled

There’s always an option to either toggle on or off Reolink’s audio recording feature. When it is disabled, you will hear no sound during video live view and playback. It may sound really glaring, but do well to confirm under the settings of Reolink Client software or on the mobile app.

3. Bad Proximity

If you are speaking on the App/Client side too far away from the microphone, it may result in low or no audio. Also, placing the camera at a height above 9 feet or being obstacles may result in poor transmission of audio.

3. Incompatible Resolution

This only applies if you are using the Reolink PoE NVR (they are like DVDs, but are used to connect multiple cameras). Specific versions of the Network Video Recorder (NVR) can only provide audio if the right output resolution is picked for it during set up.

Should the resolution be mismatched, the Reolink would produce no sound at all. We discuss how to solve this issue under the fixes.

4. Outdated App and Camera Firmware

Make sure you are using the latest version of the Reolink app on your smartphone as this may cause compatibility issues. Also, check if your Reolink camera has the latest firmware installed.

5. Reolink Just Needs a Reset

If you’ve been using your camera for some time now, a bug or error might have occurred in one of its many processes resulting which might have affected the audio. Resetting it helps you get it back to default.
