Microsoft Teams audio problems can be troubleshooted through the following steps: first check the device settings, make sure that the speaker and microphone are selected correctly and confirm the connection status; secondly, after exiting the meeting, test the audio function on the main interface to determine the source of the problem; finally troubleshoot system permissions, update the driver, replace the socket, or contact IT support to solve the "no audio input/output" problem. Step-by-step operations in sequence can usually effectively resolve common audio failures.

Sometimes when you have a meeting in Microsoft Teams, you suddenly find that you can't make a sound, you can't hear others' words, or you can't hear others' words, which is really a headache. Although these problems are not fatal, they affect efficiency when they encounter them. In fact, many common audio problems are not difficult to solve. The key is to know where to start.

Check whether the device is set correctly

Teams' audio problems are often because the device is not selected correctly. You can check this way:

• Open Teams, click on the avatar in the upper right corner → Settings → Devices
• Make sure that both the "speaker" and "microphone" are selected as the device you want to use (such as external headphones or the microphone that comes with your computer)

Sometimes the system default device has changed, but Teams still uses the old configuration. At this time, manually switching can solve the problem. If you use Bluetooth headsets, remember to confirm the connection status and the volume is not muted.

Exit the meeting before testing the audio

If you test the audio in a meeting, you may be heard by others. It is recommended to exit the meeting first and then perform the following operations:

• Click "Test hearing and microphone" on the Teams main interface
• It will automatically play a prompt to see if it can be heard normally
• Say something to the microphone, the software will detect whether there is an input signal

This test function can quickly determine whether the problem lies in the microphone or speaker. If you don't have a sound while testing, the problem may not be in Teams itself, but in the system-level setup or driver issue.

Don't rush to restart when encountering "no audio input/output"

Sometimes after opening the test page, Teams displays "Microphone not detected" or "Sound cannot be played", so don't rush to restart the software or computer. You can try these steps:

• Make sure the system permissions allow Teams to use the microphone: Go to Windows Settings → Privacy → Microphone, make sure the switch is on
• Update or reinstall the audio driver (especially when using a laptop external device)
• Try replacing the USB socket to troubleshoot hardware compatibility issues
• If it is a company computer, there may be a group policy that restricts audio access. Contact IT support is more effective

Sometimes it is a problem with Windows itself, not Teams's, so the troubleshooting starts with the basics.

Basically, these common investigation directions. The audio problem seems complicated, but most of the time it is because the device is not selected correctly, the permissions are not enabled, or the driver is a little problem. It can be done step by step in order.
