Microphone issues in Zoom can prevent you from participating effectively in online meetings, webinars, and virtual classes. On Windows 11, the problem may appear as no audio input, others being unable to hear you, or Zoom failing to detect your microphone entirely. Even if your microphone works in other applications, it may still fail specifically within Zoom due to permissions or configuration settings.
Since Zoom relies on both Windows system permissions and in-app audio settings, a misconfiguration at either level can block microphone access. Fortunately, Windows 11 provides built-in controls that allow you to verify and correct microphone permissions, device selection, and driver issues.
This guide explains how to fix microphone not working in Zoom on Windows 11 using structured troubleshooting steps.
