Hi Alejandro,

To help identify the cause, could you please confirm the following:

Is the Poly C5220 microphone not working only in Teams, or does it also fail in other applications such as Voice Recorder?
In Teams, under Settings > Devices, is the Poly C5220 selected as the microphone device?
Does Teams show any microphone activity when you speak during a test call?
Are you connected directly to the computer, or through a docking station or USB hub?

As a first troubleshooting step, please go to Teams > Settings > Devices, select the Poly C5220 as your microphone, and run a Test Call. If the test recording does not capture your voice, try disconnecting and reconnecting the headset to a different USB port and test again.

Please let me know the results, and we can process further from there. Once I have a clearer understanding of your current situation, I’ll be happy to assist you with greater accuracy. Please feel free to share any additional details you believe are relevant. Screenshots are especially helpful and much appreciated.

Thank you for your patience and your understanding. If you have any additional questions, please feel free to reach out.

I'm looking forward to your reply.
