Microphone Not Working in Slack

Slack established itself at the forefront of internal business communications. The platform offers a multitude of features that allow users, teams, and groups to pick the communication channels that best fit their needs. Slack can be easily integrated into a multitude of third-party services such as Dropbox, Google Drive, Trello, GitHub, Zendesk, and more, which facilitates easier adoption into the user's workflow. Furthermore, it is available on all major platforms - Windows, macOS, Linux, Android and iOS.

As with any software product, however, Slack can encounter issues from time to time. One that could be a source of great frustration is the inability of the application to detect the user's microphone. Although it may seem trivial, simply closing Slack and running it back again has been observed to have a high rate of success in fixing the problem. Open Slack, click on the Menu button, go to 'File,' and choose 'Quit Slack.' Now, simply navigate to Slack's shortcut and double-click it.

Make sure that the connected microphone has been set as the default recording device for the system. To check if this is the case, right-click the volume icon on the right side of the taskbar. From the available options, choose 'Sounds.' In the Sound settings window, go to the 'Recording' tab, select your microphone, and click on 'Set as Default.' All that is left is to save the change by clicking on 'Apply' and then 'OK.'

If the issue persists, then it might be a good idea to either roll back or reset your audio driver. Press the Windows key + R on your keyboard. This should open the Run dialog box. Type devmgmt.msc in it and click OK to open Device Manager. In Device Manager, locate the 'Sound, video, and game controllers section and expand it by clicking on the node icon in front of it. Double-click your audio device and go to the 'Driver' tab in its 'Properties' window. Here, you can either click on 'Roll Back Driver' to return to a previous version of the driver or choose 'Uninstall Device' to reset the driver completely. If you choose the Uninstall route, the audio driver will be removed from the computer. Restarting your PC will then force Windows to find the latest version of the driver and initiate a fresh install, hopefully fixing the issue.
