Users experiencing issues with their microphone unmuting itself on Windows can try the following solutions:
1. Check the physical mute button for functionality.
2. Review the microphone app settings for auto-unmute features.
3. Disable exclusive mode by accessing sound properties and unchecking the option for applications to take exclusive control.
4. Adjust the Communications setting in sound properties to "Do nothing."
5. Test the microphone on a different PC to determine if the issue is specific to the current configuration.
6. Contact microphone support for additional assistance or firmware updates.
Additionally, third-party software like Zoom or Skype can alter microphone settings, and voice-activated applications may automatically unmute the microphone to listen for commands.
