Audio issues during a call — choppy sound, echo, sudden silence, distorted voices — are almost always related to your internet connection or device. Go through the points below in order.
1. Slow or unstable internet connection
This is the most common cause of distorted audio, delays and interruptions. The Romulus app needs at least 1 Mbps of upload speed per device to work properly.
How to check: run a speed test at fast.com or speedtest.net. Check the upload value — if it is below 1 Mbps per device, the connection is not sufficient.
How to fix: contact your internet provider or try a different connection. Avoid using Romulus on crowded WiFi networks (e.g. public hotspots) or on 3G mobile connections.
2. Weak WiFi signal
An unstable WiFi signal causes micro-interruptions in the call that come through as choppy audio or sudden silences.
How to check: check the WiFi signal bars on your device. If the signal is low, this is likely the cause.
How to fix: move closer to the router during the call. If possible, connect your computer directly to the router with a cable — a wired connection is always more stable than WiFi.
3. Other apps or downloads running during the call
If you are streaming video, downloading files, or running updates while on a call, these activities consume available bandwidth and reduce audio quality.
How to check: check whether any downloads, streams, or updates are running on your device or on other devices connected to the same network.
How to fix: pause or close any other applications using the internet for the duration of the call.
4. Microphone or headset issues
Sometimes the problem is not the connection but the audio device. A microphone that is not correctly selected, or a faulty headset, can cause low, distorted, or missing audio.
How to check: check the audio settings in the Romulus app or your operating system to see which microphone is selected. If you have multiple audio devices connected, the wrong one may be selected.
How to fix: select the correct microphone in the settings. Try different headphones or the device's built-in microphone to determine whether the issue is hardware-related.
5. App not up to date
An outdated version of the Romulus app can cause audio issues or unexpected behaviour.
How to check: check whether an update is available for the Romulus app in the App Store (iOS), Google Play (Android), or on the Romulus website (desktop).
How to fix: update the app to the latest version and restart it. If the issue persists after updating, try clearing the app cache — see the dedicated article for the steps.
