Summary

This guide helps you troubleshoot and resolve: How to fix audio echo and feedback when using a speakerphone in meeting rooms. Follow the steps below to fix the issue.

Common Causes

Audio echo and feedback during conference calls can be distracting and make meetings difficult to follow. These issues are typically caused by microphone and speaker placement, hardware conflicts, or incorrect audio settings in Microsoft Teams and Zoom. This guide provides steps to identify and resolve echo when using a speakerphone in your meeting room.

Quick Fix Steps

1. Move the speakerphone away from walls, windows, and other reflective surfaces.
2. Ensure the microphone is not pointing directly at the speaker.
3. Lower the speaker volume to reduce the chance of audio looping back into the microphone.
4. Restart the speakerphone and reconnect it to your computer.
5. Check that only one microphone and one speaker are active in your meeting app.

Detailed Instructions

Optimise Speakerphone Placement

Physical placement is the most common cause of echo. Sound from the speaker can be picked up by the microphone, creating a feedback loop.

• Place the speakerphone in the centre of the table, away from laptops and monitors.
• Keep the device at least one metre away from glass walls or whiteboards.
• Avoid placing the speakerphone inside an enclosure or under a table.

Configure Audio in Microsoft Teams

1. Open Microsoft Teams and select the Three dots (...) next to your profile picture.
2. Choose Settings, then select Devices from the left menu.
3. Under Audio devices, ensure your speakerphone is selected for both Speaker and Microphone.
4. Make a test call to verify the audio quality.

Configure Audio in Zoom

1. Open the Zoom desktop app and click your profile picture, then select Settings.
2. Click Audio in the left sidebar.
3. Select your speakerphone from the Speaker and Microphone dropdown menus.
4. Click Test Speaker and Test Mic to confirm correct device selection.

Troubleshooting

Check for Duplicate Audio Devices

Having multiple microphones or speakers active can cause echo. For example, your laptop's built-in microphone and your speakerphone microphone may both be enabled.

1. In your meeting app, verify that the same speakerphone is selected for both input and output.
2. On Windows, right-click the speaker icon in the taskbar and select Open Sound settings.
3. Under Input and Output, ensure only your speakerphone is active.
4. On macOS, go to System Settings > Sound and check the Input and Output tabs.

Update Firmware and Drivers

Outdated speakerphone firmware can cause audio processing issues.

1. Visit the manufacturer's website for your speakerphone model.
2. Download and install the latest firmware or driver update.
3. Restart your computer after installation.

Tip: Use a headset in smaller rooms if you cannot position a speakerphone away from reflective surfaces.

Caution: Do not connect multiple speakerphones to the same computer for a single call. This will almost certainly cause echo and feedback.
