Is anyone else having problems with the Test mic and speaker function in the Microsoft Teams desktop app?

I’m using a headset and it works perfectly with YouTube and other audio, but the Teams test isn’t working. I also tried a different pair of earphones and had exactly the same issue.

I’m wondering if this is a temporary Teams bug or a known issue affecting other users, or if it’s just something on my side. I have an actual Teams meeting coming up, so I’m a little concerned, although I’m hoping the audio will work normally during the meeting.

Has anyone else experienced this recently?

    Hello !

    The AI answer is correct : there's no known bug about Teams' test call feature.

    Just to clarify : which version of Microsoft Teams are you using currently ? Is it the personal version (with a personal Microsoft account) or a business/school account (provided by your workplace) ?
    The "test call" feature does not exist yet in the free version of Teams.

    If you're using a Windows PC, make sure you've selected the correct headset in the Teams settings panel, and not a software proxy like Intel Smart Sound. If you're using a Mac, check in the System Settings if you're not blocking Teams from playing/capturing sound.

    Please let me know if you have any other question !

    The context does not identify a current known bug specifically affecting the Test mic and speaker feature in the Teams desktop app.

    Supported facts:

    • Teams provides Make a test call in Settings and more > Settings > Devices to test microphone and speaker setup before a meeting.
    • The test call feature is available in English only.
    • The test call feature is unavailable on Teams for web.
    • Microsoft recommends using the latest version of Teams and the latest Windows or macOS updates.

    Since the headset works in other apps, the documented checks are:

    1. In Teams, go to Settings and more > Settings > Devices.
    2. Under Audio settings, confirm the correct Speaker and Microphone are selected.
    3. Run Make a test call again.
    4. If the device does not appear, reconnect it. For Bluetooth devices, make sure the device is charged and not connected to another device, then reconnect it.
    5. In Windows, check Settings > Privacy & security > Microphone and make sure:
      • Microphone access is on
      • Let apps access your microphone is on
      • Microsoft Teams (work or school) is on
      • Let desktop apps access your microphone is on
    6. In Windows, check Settings > System > Sound and verify the correct input and output devices are selected and unmuted.

    A similar Q&A example in the context shows one case where low Teams audio was caused by having the mic input and listening speaker assigned to the same device, and changing the mic input resolved it.
