2. Reinstall Slack

IObit Uninstaller

If Slack couldn’t find your microphone, perhaps the problem is related to the application itself. Sometimes your installation can get corrupted, and in order to fix the problem, it’s advised that you reinstall it.

There are several methods that you can use to reinstall an application, but the most effective one is to use an uninstaller software tool.

In case you don’t know, uninstaller software is an application that can remove any software from your PC, along with all of its files and registry entries.

If you’re looking for a reliable choice, we suggest that you try IObit Uninstaller. As a result, it will completely remove the application and prevent leftover files from interfering with your system.

If Slack couldn’t find your microphone, perhaps the problem is the microphone. To fix this problem, it’s advised that you test your microphone in other applications.

If your microphone works in Steam, Skype, or any other application, the problem isn’t related to the microphone, and most likely the microphone isn’t properly configured in Slack.

4. Check if your microphone is set as the default recording device

  1. Right-click the volume icon in the bottom right corner of the Taskbar. Choose Open Sound settings from the menu.
