When you're ready to join a video call and see the dreaded "Google Meet can't use microphone" message, it can stall your productivity. This issue typically stems from blocked browser permissions, incorrect system audio settings, or hardware conflicts.
Most audio drivers on Windows operate on an "exclusive mode" principle. If another application—Zoom, Teams, Discord, or even a browser tab playing YouTube—has already "locked" the microphone driver, Google Meet’s request to the browser will be rejected.
Sometimes, the browser's helper processes or an update to the browser binary can invalidate previous permissions. The OS sees the "new" version of Chrome as a different entity and revokes microphone access without a clear notification, leaving Google Meet unable to request the stream.

One of the most common reasons for microphone failure in modern computing is the "Privacy by Design" approach adopted by OS manufacturers.
While the immediate reaction is often to blame the hardware or the internet connection, the reality is far more complex. Google Meet operates within a browser environment, sandboxed by layers of operating system security. When the microphone fails, it is rarely a simple malfunction; it is usually a breakdown in the chain of custody between the physical hardware, the Operating System (OS), the browser, and the web application.
