Why Your Mic Works in Discord but Not Zoom (2026 Guide)
Quick answer: When your mic works in Discord but not Zoom (or the other way round), the problem is almost always inside the app that fails — a muted setting, the wrong input device selected, or a missing permission — not the microphone. Prove the mic itself is fine with the microphone test, then fix the app.
Each app has its own input
Zoom, Discord, Teams and Chrome each remember their own microphone selection, independent of Windows. After a device change or an update, one app may still point at an old or disconnected input while another picks the right one. Open the failing app's audio settings and explicitly choose your current microphone, then use its built-in mic test.
Check the per-app permission
On both Windows 11 and macOS, permissions are granted per app. A recent update can revoke access for one program while leaving others untouched. On Windows, check Settings, Privacy & security, Microphone, including the desktop-apps toggle. On macOS Tahoe, check System Settings, Privacy & Security, Microphone.
The exclusive-mode conflict
If one app is holding the microphone in exclusive mode, another app trying to use it at the same time gets silence. On Windows, open the mic's Advanced properties and untick "allow applications to take exclusive control." This is a frequent cause of the "works in one app, dead in the other" pattern, especially when both apps are open together.
Isolate it cleanly
The fastest diagnosis is the microphone test: if your level meter moves there, the mic and driver are healthy and the fix is entirely inside the app. From there, our step-by-step guide on a mic not working on Zoom covers the exact settings to change.
