Fix microphone issues in Teams and apps that won't launch

Introduction

If your microphone is not working properly during Microsoft Teams calls and you also cannot launch other applications on your computer, this guide can help you narrow down the cause and try common fixes. These issues are often related to device settings, app conflicts, or a system restart being needed.

Issue description

This troubleshooting guide covers two related problems: microphone issues in Teams calls and problems opening other applications on your computer. In some cases, both symptoms may be caused by the same system issue, such as a temporary software conflict, a permissions problem, or a computer that needs to be restarted.

Signs

• Other people cannot hear you in Teams calls
• Your microphone sounds distorted, very quiet, or cuts in and out
• Teams does not detect the correct microphone
• Applications fail to open when you click them
• Your computer seems slow, frozen, or unresponsive

Basic troubleshooting steps

Start with these simple checks before moving to more advanced steps.

1. Check that your microphone is properly connected.

2. Make sure the microphone is selected as the active input device in Teams and in your computer’s sound settings.

3. Confirm that the microphone is not muted on the headset, keyboard, or in Teams.

4. Close Teams and any other open programs, then restart your computer.

5. Try opening the other application again after the restart.

6. If Teams still does not work correctly, reinstall the Teams application.

Advanced troubleshooting steps

Step 1: Verify microphone permissions and device settings

Check your operating system’s privacy or sound settings to make sure Teams is allowed to use the microphone. Then confirm that the correct microphone is selected and that input levels are not set too low.

Step 2: Restart the computer

A restart can clear temporary software conflicts that affect both audio devices and application launching. Save any open work, restart the computer, and test Teams and the other application again.

Step 3: Reinstall Teams

If the microphone issue continues only in Teams, uninstall and reinstall the Teams application to replace any damaged files or settings.

Step 4: Check for software conflicts

If other applications still will not open, look for recently installed software, security tools, or background programs that may be interfering with normal system behavior. Try closing unnecessary programs and testing again.
