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.

Frequently asked questions
Why does my mic work in Discord but not Zoom?
Each app remembers its 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.
Can an update revoke microphone access for just one app?
Yes. Permissions are granted per app on both Windows 11 and macOS, so an update can revoke access for one program while leaving others untouched.
What is exclusive mode and how does it silence an app?
If one app holds 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."
How do I tell whether the mic or the app is at fault?
Run a microphone test. If the level meter moves there, the mic and driver are healthy and the fix is entirely inside the failing app.
If you are on a Mac, check which macOS you are heading for
macOS Tahoe is the last version of macOS that runs on Intel Macs. Its successor, macOS 27, was announced at WWDC 2026 and is Apple Silicon only.
This matters for the per-app microphone permissions described below. Because permission is granted per app and not system-wide, Discord having microphone access tells you nothing about whether Zoom does — that is the whole reason one works and the other does not. Both entries live separately in System Settings, Privacy and Security, Microphone.
On Intel Macs, Tahoe is the final macOS release, so the permission behaviour described here is stable for the life of the machine. On Apple Silicon, macOS 27 keeps the same per-app model, so the diagnostic order below does not change.
