| How to Fix Echo and Feedback on Video Calls |
Echo on a video call is one of the most immediately disruptive problems a meeting can have, and the frustrating part is that it's very often not your own fault at all — but knowing how to quickly diagnose whose echo it is saves everyone real time.
Understanding Where Echo Comes From
Echo happens when a microphone picks up sound that already came from the meeting itself — usually a speaker playing another participant's voice — and sends it back into the call. This means echo is almost always caused by whoever's microphone is picking up their own speakers, not by the person who complains about hearing it.
Step 1: Figure Out Whose Echo It Actually Is
Ask everyone on the call to mute one at a time. If the echo disappears when a specific person mutes, the echo is coming from their microphone, regardless of who's complaining about hearing it.
Step 2: If It's You — Check for Multiple Devices Open
The most common cause of self-caused echo is having the same meeting open in more than one place at once — a laptop and a phone both joined, for example. Each device's microphone picks up the other's speaker output.
Fix: Close every extra instance of the meeting except one.
Step 3: If It's You — Use Headphones, Not Speakers
Speaker output being picked back up by your own microphone is the second most common cause.
Fix: Switch to any headphones, even basic wired ones, which physically separates the sound from your microphone's pickup path.
Step 4: Already Using Headphones and Still Hearing Echo
This usually comes down to one of two things: a loose or partially connected headphone jack or Bluetooth pairing letting audio leak to built-in speakers, or a second microphone (like a laptop's built-in mic) still active alongside your headset. Check your call app's microphone selection specifically — as covered in our guide on cameras and devices not being detected correctly, apps sometimes default to the wrong input device even when a better one is connected.
Step 5: If It's Someone Else — What to Suggest
Once you've identified the source through the muting test in Step 1: ask them to check for a second device joined, suggest headphones if they're on speakers, or suggest checking their microphone selection if they're already on headphones.
Step 6: Check the Platform's Echo Cancellation Settings
Most conferencing apps include automatic echo cancellation, but it isn't always tuned aggressively by default. Check your platform's audio settings for a "noise suppression" or "echo cancellation" toggle.
Step 7: Rule Out Room Acoustics
In a room with hard, bare surfaces, sound can bounce enough to resemble echo even with good equipment. This is worth considering only after ruling out every device-level cause above.
Quick Diagnostic Summary
| Symptom | Likely cause | First fix |
|---|---|---|
| Echo disappears when a specific person mutes | It's their setup | Suggest they check devices/speakers |
| Same meeting open on two of your devices | Duplicate device echo loop | Close the extra device's meeting window |
| You're on speakers | Speaker-to-mic feedback | Switch to headphones |
| Echo continues despite headphones | Wrong mic still active | Check mic selection and connection |
If your headset is provided by your employer, check with IT if echo persists, particularly if it may relate to centrally managed audio drivers.
