What you’re seeing
- Colleagues on a Teams call say they cannot hear you, even though you can hear them.
- The microphone level bar in Teams does not move when speaking.
- Teams shows a message that no microphone was found, or uses the laptop's built-in mic instead.
- The headset mic works in other apps or on another computer, but not in Teams.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Teams is set to a different microphone than the headset, often after the headset was reconnected.
- Windows privacy settings block Teams or desktop apps from using the microphone.
- Bluetooth headsets switch to a profile that supports audio playback only, without the microphone.
- The headset's own mute button or boom mic position has muted the microphone.
- Audio drivers or headset software from Jabra, Poly or Logitech are outdated or conflict with Teams.
- New Teams and classic Teams store device settings separately, so changes in one do not carry over.
Why it matters
Teams calls are where sales, support and internal decisions happen. When a microphone fails, meetings start late, customers are kept waiting and staff have to dial in by phone or switch devices. Repeated audio problems make the business look unprepared to clients. For support teams handling calls all day, a broken mic can take a person out of the queue entirely until it is fixed.

A certified engineer diagnoses it
A vetted, US-based systems engineer claims your ticket, usually within minutes during business hours, and investigates over a secure remote session you can watch and end at any time.
Fixed and verified with you
The engineer resolves the root cause and confirms with you that it’s working. You don’t just get a workaround, and you get a plain-English summary of what was wrong.

Frequently asked questions
Why does the mic work in Zoom but not Teams?
Each app picks its own audio device and permissions, so Teams may simply be using the wrong input or blocked by a setting.
Is our headset broken?
Usually not, especially if it works elsewhere. Settings, drivers or Bluetooth profiles are more common causes.
How quickly can it be fixed?
Often in a single remote secure session with a certified US engineer, from $99, and you pay only when resolved.
