Microphone picking up desktop sound

Hello Luthfi Amir Suhaimi,

Thanks for reaching out here in the Microsoft Answers Community.

We are unable to determine the issue, as there are multiple ways to achieve this.

Try disabling stereo mixing first. To do so, press Windows+R and enter "mmsys.cpl". Go to the "Recording" tab, and if there is a "Stereo mix" microphone, disable it, and see whether the issue persists.

If there is no such devices, it could be set up by third-party applications. You can try performing a clean boot first to rule out the influence of third-party software, and see whether the issue persists.

To do so, right-click Start->Task manager. Go to the "Startup" tab, and disable all startup items. Then, press Windows+R and enter "msconfig". Go to the "Services" tab, select "Hide all Microsoft services", and then select "Disable all". Select Apply and reboot. See whether the issue persists.

Please refer to this support article for details, and how to pinpoint the application causing the issue.

Disclaimer: A "clean boot" starts Windows with a minimal set of drivers and startup programs.

It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.

These steps of "clean boot" might look complicated at first glance; however to avoid any trouble for you, please follow them in order and step-by-step, so that it will help you get back on track.

We look forward to your response.
