This is usually a driver-selection or USB device detection issue, not a permanent mute problem. When the webcam is connected, Windows may switch audio handling, fail to load the expected audio device correctly, or trigger a USB audio problem.
Try these steps in order:
- Check whether the main audio device is being disabled
- Open Device Manager.
- Expand Sound, video and game controllers.
- If the laptop audio device appears, right-click it and select Enable device if that option is available.
- If the device does not appear, select View > Show hidden devices, then Action > Scan for hardware changes.
- Check sound settings after plugging in the webcam
- Select Start > Settings > System > Sound.
- Make sure the output and input devices are not disabled in Device properties.
- Also check the taskbar Speakers icon > Open Volume mixer and confirm nothing is muted.
- Set the correct playback device as default
- Open Control Panel > Hardware and Sound > Sound.
- On the Playback tab, select the laptop speakers or the intended audio device.
- Choose Set as Default Device.
- This is important because USB devices can cause Windows to prefer a different audio endpoint.
- Reconnect the webcam and test another USB port
- Disconnect the webcam and reconnect it.
- If the issue continues, connect it to a different USB port.
- Microsoft documents that some USB audio/video devices can malfunction depending on the USB connection path, and reconnecting or changing ports can help.
- Update or reinstall the audio driver
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the laptop audio device and select Update driver > Search automatically for drivers.
- If that does not help, uninstall the audio device and restart the PC so Windows reinstalls it automatically.
- Save open work before restarting.
- Install the latest manufacturer drivers
- Install the latest audio driver from the ASUS support site for the exact laptop model.
- If the webcam has its own driver or firmware package, install that before reconnecting it.
- Microsoft also documents that installing the device-specific driver before connecting a USB audio device can prevent Windows from choosing the wrong default driver.
- If the laptop is Intel-based, test for the documented USB issue
- A known issue affects some Intel systems with 500, 600, or 700 series chipsets that use a discrete TPM (dTPM).
- Symptoms can include USB audio or video devices glitching or stopping.
- The documented workaround is to unplug and reconnect the device, and if needed restart the PC.
Most likely causes in this scenario:
- Windows is switching the default audio device when the webcam is attached.
- The ASUS audio driver is being disabled or not reloaded correctly when the USB webcam initializes.
- The webcam or USB controller is triggering a USB audio/video device issue on that hardware.
If the problem only happens with this webcam, the most targeted fix is:
- update the ASUS audio/chipset drivers,
- install any webcam-specific driver first,
- then reconnect the webcam on a different USB port,
- and re-check the default playback device.
