OBS Microphone Has No Input

Prove the microphone signal before changing OBS sources, mixer routing or audio monitoring.

Evidence first

What the independent test changes

If DeviceOK passes

A DeviceOK input signal strongly suggests the microphone/browser path works; OBS source/mixer routing becomes the likely layer.

If DeviceOK fails

If DeviceOK sees no input, troubleshoot the microphone connection, mute and OS permissions first.

Safe sequence

Check these in order

  1. 1

    Run DeviceOK Microphone Level Test and confirm live input.

  2. 2

    In OBS, verify the correct audio input source/device is selected.

  3. 3

    Check the OBS Audio Mixer for mute/level state.

  4. 4

    If DeviceOK works but OBS does not, focus on OBS source selection/routing before drivers.

Verify

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.
