Slack Huddle Microphone Not Working

Test microphone input independently, then check Slack's huddle audio preferences and operating-system/browser access.

Evidence first

What the independent test changes

If DeviceOK passes

A DeviceOK mic pass makes a total microphone failure less likely; focus on Slack selection and permission.

If DeviceOK fails

If DeviceOK receives no input, troubleshoot the device/OS path first.

Safe sequence

Check these in order

  1. 1

    Run DeviceOK Microphone Test.

  2. 2

    In Slack huddle preferences, select the intended microphone.

  3. 3

    Check OS/browser microphone permission for Slack.

  4. 4

    Use Slack's troubleshooting panel/guidance if the hardware works elsewhere.

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.
