Quick answer: Enable acoustic echo cancellation on the capture path, add noise suppression and a gate, and detect feedback loops to auto-suggest headphones or duck output.

Echo in voice chat is almost always speaker audio bleeding into an open mic and being retransmitted. Without acoustic echo cancellation everyone hears a delayed copy of themselves. Enabling AEC on capture is the core fix.

How to fix it

1. Enable acoustic echo cancellation

Route the mic through an AEC stage (built into WebRTC and most voice SDKs) that subtracts the known playback signal from the capture, removing the looped-back voices.

2. Add a noise gate and suppression

A gate that only opens above a speaking threshold, plus noise suppression, keeps low-level speaker bleed from ever crossing into the transmitted stream.

3. Detect loops and nudge headphones

If you detect sustained correlated output-in-input, surface a one-time prompt suggesting headphones or automatically lower output volume while that player speaks.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

The errors you never hear about are the ones quietly costing you players. Visibility turns them into a worklist.
