USB headset microphone disappears after Teams update

Minimal guidance for messy support realities.

Scenario

A user still hears audio through a USB headset, but the microphone vanishes from app input choices after an update.

Recommended Resolution Path

  1. Check Windows sound input devices and privacy permissions outside the meeting app first.
  2. Review whether the headset enumerated as a new device after firmware or driver changes.
  3. Test the headset on another USB port and another workstation to rule out hardware failure.
  4. If only one app misses the mic, clear its cached device preferences and retest.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
