USB mic not working after BIOS update

Hi. I'm on Windows 11. I have an MSI motherboard and a 13th Gen Intel i7 13700KF processor. And I have a simple Logitech USB headset.

I did a BIOS update last night because of the Vmin Shift Instability issue. After the update, my headset mic stopped working. The headset speakers work just fine, but the mic doesn't. Windows registers the device in both Device Manager and Sound Settings. It shows the microphone as enabled and working properly. However, if I try to use it in Discord or Windows Sound Recorder, it says "no audio input device detected". To make sure it wasn't a hardware issue, I tested this headset on my laptop (Windows 10) and the microphone works just fine.

I've tried uninstalling the headset mic and speakers in Device Manager, unplugging the headset, rebooting my PC, and plugging the headset back in. I've tried changing the USB port it's plugged into. I checked for driver updates and installed what came up. I ran DSIM repair, I did a sfc scan. And yes, I checked to make sure the mic isn't muted - it's not. Nothing has fixed it. I was bumping up against the "reinstall Windows" last resort, but I really don't want to do that if I can help it...

Which is when I remembered that I have a FIFINE USB microphone collecting dust in my closet, so I decided on a whim to plug that in and see if it worked. To my surprise, it DOES. So right now, it seems like Windows hates my Logitech headset's microphone specifically, which is truly absurd. I'm at a loss here.

Any ideas?

    Since the headset is detected, the speakers work, and another USB microphone works on the same PC, start with the Windows input path rather than reinstalling Windows.

    1. Confirm the Logitech mic is the active input device.
      • Go to Start > Settings > System > Sound.
      • Under Input, in Choose a device for speaking or recording, select the Logitech headset microphone.
      • Open its properties with the > button.
      • Under Microphone test, select Start test, speak, then Stop test and Play.
      • If the recorded sample is empty, continue with the steps below.
    2. Recheck microphone privacy permissions.
      • Go to Start > Settings > Privacy & security > Microphone.
      • Turn on Microphone access.
      • Turn on Let apps access your microphone.
      • If Discord is the main failing app, make sure that app is enabled in the list.
      • Also turn on Let desktop apps access your microphone.
      • Then test again in Sound Recorder first, and after that in Discord.
    3. Run the built-in recording troubleshooter.
      • Go to Settings > System > Sound.
      • Scroll to Advanced.
      • Run Input devices under Troubleshoot common sound problems.
      • If needed, open All sound devices under Advanced for additional options.
    4. Reinstall the audio device entries again, but remove all related audio devices under the audio controller section too.
      • Right-click Start > Device Manager.
      • Expand Sound, video and game controllers.
      • Right-click each audio device related to the headset/audio stack and select Uninstall device.
      • If offered, check Attempt to remove the driver for this device.
      • Restart the PC.
      • After restart, if Windows does not restore them automatically, in Device Manager right-click Sound, video and game controllers and select Scan for hardware changes.
      • Then right-click the audio driver and select Update driver.
    5. Make sure Windows is fully updated and any pending restart is completed.
      • Go to Start > Settings > Windows Update > Check for updates.
      • Install available updates.
      • If Update and restart appears in the Power menu, use it.
    6. Restart the Windows audio services.
      • Search for services from the taskbar.
      • Restart these services:
        • Windows Audio
        • Windows Audio Endpoint Builder
        • Remote Procedure Call (RPC)
    7. If the headset is Bluetooth, re-pair it. If it is wired USB, keep testing different USB ports.
      • The current symptoms do not match the documented Intel dTPM USB issue exactly, because another USB microphone works, but if the headset is USB and the problem began right after firmware changes, a simple unplug/reconnect and reboot is still a valid workaround.
    8. If Windows still shows the Logitech microphone as present but apps report no input, an in-place repair install is the supported last resort before a full reset.
      • The referenced Microsoft Q&A resolution for broad USB device/driver corruption is an in-place upgrade using the latest Windows 11 ISO while keeping files.
      • This reinstalls Windows without requiring a wipe.

    The strongest clues here are:

    • the Logitech mic is detected but produces no usable input,
    • the headset works on another PC,
    • a different USB microphone works on this PC.

    That points more to a Windows input/permission/driver-state problem for that specific device path than to a failed headset or a general USB failure.

    Hi!

    Please provide the full model name of your motherboard as well as your headset. This information is important.

    • Press WINDOWS + R > Type "msinfo32" > Send me a screenshot of the "System Summary" page.
    • The "System Summary" page includes the version of the BIOS currently installed, which will also be important.
    • Press WINDOWS + R > Type "winver" (no quotes) > Take a Screenshot of the Window and send it to me

    Hi Ashley,

    Since the Logitech headset microphone works on another PC, another USB microphone works on this PC, and you’ve already reinstalled the device, changed USB ports, updated drivers, and run SFC/DISM.

    Given that the issue appeared immediately after updating the BIOS on your MSI PRO Z690-A WIFI, you should check the MSI support page for this exact motherboard next. Compare the installed A.N0 BIOS with the currently available BIOS releases and review the release notes for any USB/audio-related changes. Also install the current motherboard chipset drivers directly from MSI if they are newer than those presently installed.

    If the behavior remains specific to the Logitech headset after that, I’d recommend contacting MSI Support with the BIOS version and the before/after behavior. That would help determine whether there is a BIOS/USB compatibility issue before making major changes to Windows.

    I hope this helps narrow the investigation without putting you through an unnecessary Windows reinstall.
