Why Won't Two-Way Audio Work on My Arlo Camera?
- Arlo app not granted microphone permission
- Phone volume/mute or Bluetooth routing
- Weak WiFi causing audio dropouts
Problem Description
Two-way audio on your Arlo camera is not working — you can't hear the other person or they can't hear you. Two-way audio requires microphone and speaker permissions to be enabled in the Arlo app and on your phone. The camera's built-in microphone (typically on the front) and speaker need a clear path for audio.
Why This Happens in Real Homes
Two-way audio problems are usually the phone side or the connection, not the camera. The number-one cause is the Arlo app not having microphone permission — without it, the camera can't hear you. After that, a weak WiFi signal makes audio choppy or one-way, since voice needs a steady stream in both directions.
Start by granting the app mic permission and checking your phone isn't muted or routing audio to a Bluetooth device, then improve the camera's signal. Confirm the camera's mic and speaker aren't muted in settings, and use the push-to-talk control as designed — half-duplex audio means you take turns.
Symptoms
- Cannot hear the other person
- They cannot hear you
- No audio at all in live view
- Audio cuts out or lags
- Echo or feedback
- Mic permission prompt
- One-way audio only
- Audio worse on a weak signal
Recognize these? Here's what usually causes it.
Common Causes
- Arlo app not granted microphone permission
- Phone volume/mute or Bluetooth routing
- Weak WiFi causing audio dropouts
- Push-to-talk not held/tapped correctly
- Camera mic or speaker muted in settings
- Two-way audio not supported/enabled on the model
- Latency from a slow connection
- App or firmware out of date
Most fixes happen in the first 3 steps.
Security cameras should be installed at least 8 feet high to prevent tampering. Check local laws regarding recording audio and video. Never aim cameras at neighboring private property. Outdoor cameras should be rated IP65 or higher for weather resistance.

Step-by-Step Solution
Check microphone and speaker permissions
Two-way audio requires your phone to have microphone permission granted to the Arlo app. On iOS, go to Settings, Arlo, and verify Microphone is enabled. On Android, go to Settings, Apps, Arlo, Permissions, Microphone. If the permission was denied, the talk button appears in the app but no audio is transmitted to the camera.
Test the talk button in live view
Open the camera live view in the Arlo app and tap the microphone or talk button. Speak clearly and listen at the camera location. There is a 1-3 second delay between speaking and hearing audio from the camera speaker. If you hear nothing, increase the camera speaker volume in the camera settings. Some Arlo cameras have low default speaker volumes that are hard to hear outdoors.
Fix echo and feedback loops
If you hear your own voice echoing back through your phone, the camera microphone is picking up its own speaker output and sending it back. This happens when speaker volume is too high or the camera is in a small enclosed space. Lower the camera speaker volume or switch to push-to-talk mode (hold to speak, release to listen) instead of full duplex mode if your model supports it.
Check WiFi bandwidth for audio
Two-way audio adds bandwidth requirements on top of the video stream. If your WiFi connection to the camera is marginal (1-2 bars), the audio may cut in and out, have long delays, or not work at all. The video stream gets priority — audio is dropped first when bandwidth is limited. Improve WiFi signal to the camera or reduce video quality to free up bandwidth for audio.
Verify the camera hardware supports two-way audio
Not all Arlo camera models have a speaker. The original Arlo wire-free cameras have a microphone but no speaker — they can pick up audio for recordings but cannot play audio back. Two-way audio requires both a microphone and speaker, which is available on Arlo Pro and later models. Check your camera model specifications to confirm speaker support.
Quick Solutions
Still having issues? This is usually the deeper cause below.
Camera issues that start suddenly almost always trace back to an upload bandwidth drop — run a speed test before assuming hardware failure.
Set up activity zones to monitor only the areas that matter like your front porch and driveway and exclude the street. This dramatically reduces false alerts while ensuring you never miss an actual event at your property.
Live view problems that start suddenly usually trace back to an upload speed drop — the camera itself is fine, the bandwidth path to the cloud isn't.
