Microphone on logi HD1080p camera not working

I swapped a motherboard on an office Windows 11 workstation. Everything works fine with this motherboard except for the microphone on the logitech HD1080p camera. The camera itself does work. This camera/mic worked fine with the previous motherboard. A camera worked fine with this motherboard when in a different computer. In Device Manager the microphone driver is listed as "C615 HD WebCam", not HD1080p. So, I removed that driver, then rebooted. When it came back up the same C615 drive reappeared.

Per a web suggestion I tried changing the camera to a different USB port and powering off/on. That didn't help.

I also tried running the 'Sound Recorder' app, but it said, "No Audio Input available."

What else can I do to get this microphone to work? Thanks

    Welcome to Microsoft Q&A!

    Thank you for providing the detailed information.

    Since the webcam's video function is working but Sound Recorder reports "No Audio Input available," Windows is recognizing the camera portion of the device but does not appear to be detecting the webcam's microphone.

    Please try the following troubleshooting steps:

    1. Verify that the microphone is detected by Windows

    • Go to Settings > System > Sound > Input.
    • Check whether the Logitech webcam microphone appears in the list of recording devices.
    • If it appears, select it and run a microphone test.

    2. Check microphone privacy settings

    • Go to Settings > Privacy & security > Microphone.
    • Ensure that:
      • Microphone access is enabled.
        • Let apps access your microphone is enabled.
          • Let desktop apps access your microphone is enabled.

    If these settings are disabled, Windows may prevent the webcam microphone from being detected or used by applications.

    3. Check Device Manager for the webcam audio device

    • Open Device Manager.
    • Expand Audio inputs and outputs and sound, video and game controllers.
    • Look for a USB Audio Device, Logitech microphone, or any device with a warning icon.
    • If no audio device appears, select Action > Scan for hardware changes.
    • If the webcam audio device is present, uninstall it, select Attempt to remove the driver for this device, and restart the PC. Windows should reinstall the device automatically.

    4. Install the latest motherboard drivers

    Because the issue began immediately after the motherboard replacement, install the latest from the motherboard manufacturer's support site:

    • Chipset drivers
    • USB controller drivers
    • Audio drivers

    An outdated or missing chipset/USB driver can prevent the webcam's USB audio interface from enumerating correctly, even while video continues to function.

    5. Show hidden devices

    • In Device Manager, select View > Show hidden devices.
    • Remove any grayed-out or stale webcam and USB audio entries, then reconnect the webcam and allow Windows to rediscover it.

    6. Test using the Microsoft in-box driver

    • Logitech webcams are generally UVC/UAC-compliant devices and normally work with the drivers included in Windows.
    • If Windows is using a vendor-specific driver, try updating the device and selecting the standard USB Video Device driver where available.
    • Please notes that switching to the built-in UVC driver can resolve certain webcam-related detection issues.

    Given that:

    • The webcam and microphone worked on the previous motherboard,
    • The webcam works correctly on another computer, and
    • Windows is reinstalling the same webcam device after removal,

    I would focus on the motherboard chipset/USB drivers and whether the webcam's USB audio device appears in Device Manager. If no audio device is detected at all, Windows is likely failing to enumerate the microphone portion of the webcam rather than there being an issue with the Sound Recorder application itself.

    Since the camera works but Windows reports No Audio Input available, focus on microphone privacy, input selection, and driver re-detection.

    1. Check microphone privacy in Windows 11:
      • Go to Start > Settings > Privacy & security > Microphone.
      • Turn on Microphone access.
      • Turn on Let apps access your microphone.
      • Turn on Let desktop apps access your microphone.
      • If the webcam includes a microphone, also go to Start > Settings > Privacy & security > Camera and make sure Camera is turned on.
    2. Check whether Windows can see any input device:
      • Go to Start > Settings > System > Sound.
      • Under Input, select the microphone if it appears.
      • Use Start test, speak normally, then Stop test and Play to verify capture.
      • If no microphone appears there, Windows is still not detecting the webcam microphone as an input device.
    3. Force hardware re-detection in Device Manager:
      • Try the webcam in a different USB port again.
      • Open Device Manager.
      • Look under Sound, video and game controllers for audio devices.
      • If the webcam audio device is missing or incorrect, select Action > Scan for hardware changes.
      • Restart the PC and test again.
    4. Reinstall the audio device driver:
      • In Device Manager, expand Sound, video and game controllers.
      • Right-click the webcam-related audio device and select Uninstall device.
      • Select the checkbox to remove the driver for the device, then uninstall.
      • Restart the computer.
      • If Windows does not reinstall it automatically, return to Device Manager and select Scan for hardware changes.
      • Then right-click the audio driver and select Update driver.
    5. If the webcam is external, rule out port-level detection issues:
      • Connect it to another USB port.
      • If needed, test it on another device to confirm the microphone hardware still enumerates correctly.

    The C615 HD WebCam name by itself does not confirm a failure. The more important symptom is that Windows shows no audio input device. If the microphone still does not appear after privacy checks, uninstall/reinstall, scan for hardware changes, and driver update, Windows is not detecting the webcam microphone portion correctly on that workstation.
