How to fix constant echoing in R.E.P.O. voice chat

If you're hearing echo in R.E.P.O. voice chat, try these steps: 1. Lower mic sensitivity and speaker volume in Sound settings. 2. Use headphones instead of speakers. 3. Disable audio enhancements like echo cancellation in R.E.P.O. 4. Ensure only one microphone is active in system settings.

If you're experiencing constant echoing in R.E.P.O. voice chat, it can disrupt communication and gameplay. Here are effective methods to resolve the issue:

The operating environment of this tutorial: MacBook Air, macOS Sonoma

1. Adjust Microphone and Speaker Settings

Improper microphone sensitivity or speaker volume can cause audio feedback, leading to echo. Reducing input and output levels can minimize sound loops.

• Open System Settings and navigate to Sound.
• Under the Input tab, lower the microphone sensitivity and disable "Use ambient noise reduction" if enabled.
• In the Output tab, reduce the speaker volume to below 80% to prevent sound from being picked up again.

Ensure your microphone is not set to "Boost" mode, as this amplifies background noise and increases echo risk.

2. Use Headphones Instead of Speakers

Using external speakers allows your microphone to pick up audio output, creating a feedback loop. Switching to headphones isolates the audio path.

• Connect a wired or Bluetooth headset to your device.
• Go to Sound settings and set the headset as the default output device.
• Verify the microphone input is still assigned to your preferred mic, not the headset unless intended.

Wearing headphones significantly reduces the chance of audio leakage and echo during voice transmission.

3. Disable Audio Enhancements in R.E.P.O.

Some voice chat applications include audio processing features like echo cancellation or noise suppression that may malfunction and cause echo instead of preventing it.

• Launch R.E.P.O. and access Voice Chat Settings.
• Locate the Audio Processing section and turn off options such as "Echo Cancellation," "Noise Suppression," or "Automatic Gain Control."
• Restart the voice chat and test for echo.

Disabling conflicting audio enhancements can eliminate software-induced echo loops.

4. Check for Multiple Active Input Devices

Having more than one microphone or input source active simultaneously can cause overlapping audio signals, resulting in echo.

• Go to System Settings > Sound > Input.
• Ensure only one microphone is selected and all others are disabled.
• If using an external mic, disconnect unused audio peripherals.

Only one input device should be active at a time to prevent audio duplication and feedback.
