2] Check the microphone app

Some microphone OEMs offer software to enhance their functionality and add more features. Some microphones auto-unmute as soon as someone starts speaking.

If your microphone has something similar, check the app settings to see if there are auto-unmute or level-related checks that could affect the mute.

Disable any unnecessary applications that might interact with your microphone.

Also, check background apps in Settings > Apps > Installed apps or Privacy & security > Microphone to ensure only trusted apps have mic access.

Navigate to:
Computer Configuration > Administrative Templates > System > Device Installation > Device Installation Restrictions
Enable the setting:
- Prevent installation of devices not described by other policy settings
- Prevent installation of devices that match any of these device IDs (specific to your microphone’s hardware ID)

If possible, connect your microphone to another PC running a different version of Windows to determine if the issue persists. This can help identify if the problem is specific to your current PC configuration.

If none of the above solutions work, contact microphone’s customer support for further assistance. They may have additional insights or firmware updates to resolve the issue.
