What the independent test changes
If DeviceOK receives normal microphone audio, a completely dead microphone is unlikely; focus on Zoom device selection, Zoom/OS permission and routing.
If DeviceOK cannot receive audio either, troubleshoot detection, mute, connection and OS microphone access before Zoom-specific settings.
Check these in order
- 1
Run DeviceOK Microphone Test and confirm a live input signal.
- 2
In Zoom Audio settings, confirm the intended microphone is selected rather than a monitor, webcam mic or disconnected headset.
- 3
Use Zoom's built-in Test microphone flow and listen for the replay.
- 4
If DeviceOK works but Zoom does not, check Zoom's microphone permission at the operating-system level before changing drivers.
Retest instead of guessing
After changing one setting, run the independent DeviceOK test again before moving to a more invasive step. This preserves evidence and avoids changing multiple variables at once.
