Resolution

A detected microphone should appear in Microsoft Teams in Settings > Devices > Microphone.

If you have a microphone or device with one attached to your PC and None is listed in the Microphone section, you will need troubleshoot this issue either with your microphone, audio headset, or the PC it is connected to.
