Recently my internal laptop microphones completely stopped working. it was fine during 14/9/2026 but after messing with FL Studio for awhile, my Microphone refuses to pick up any audio at all. Ive gotten microsoft support today but none worked. This is driving me crazy, any suggestions?

    If this does not work, please try downloading and installing the latest Chipset driver and BIOS update from the manufacturer's support page and let me know how it goes.

    You likely have installed KB5124008 update. Some other users reported similar issue after that update. So you can uninstall KB5124008 update to fix the issue that it causes. The KB5124008 update fixes a large number of vulnerabilities, including actively exploited zero‑days. Uninstalling it significantly reduces your security posture, so you should only uninstall and test if microphone (or other critical features) doesn't work and you need them. Here are the release notes: https://support.microsoft.com/en-us/servicing/os/windows-11/2026/09/kb5124008-windows-11-24h2-25h2-security-update

    In case you want to uninstall:

    1. Open Settings > Windows Update > Update history > Uninstall updates.
    2. Uninstall KB5124008
    3. Pause Windows Update so it doesn’t get reinstalled, and resume it later when Microsoft has fixed it in an upcoming update.

    Hi, good day!

    Since Microsoft Support has already tried some troubleshooting steps, could you share which solutions you've attempted so far? This will help me avoid repeating the same steps.

    Also, could you provide your laptop's make and model and confirm whether the internal microphone works in other apps, such as Voice Recorder?

    Press Start then search msinfo to open System Information

    Please take a screenshot of the resulting window and post it in your next response.

    I look forward to your update and am willing to collaborate with you until we resolve the issue. Keep me posted by clicking "Add comment" below.
