This is a Windows setting.
In Windows 10, use the Privacy page to choose which apps can use a particular feature. Select Start  > Settings  > Privacy. Select the app and choose which app permissions are on or off. 

We would advise to use the Skype desktop app instead of the browser version. 
Also make sure to download this app from the Skype website rather than from the Windows App store. 
 

Check the image orientation in the application that you are using the webcam with. This setting is either normal or mirrored. 

Please note that in some meeting applications the "selfview" (or preview) may be flipped but the other participant(s) in the meeting will see it the correct way. 

We recommend to check the following:

• Microphone privacy settings: Check if the microphone allows apps to access the microphone
• Default device: Check if the microphone has been selected as the default sound input device on the computer
• Windows Update: Check if Windows is up-to-date via windowsupdate.com

Try the product on another device, does the microphone function on another device?

- Make sure that webcam has been correctly installed
- When using Windows 10: Make sure the webcam (and if applicable, its microphone) are allowed in the Privacy settings to be used by the application
- In order to use the webcam with a program, we would advise you to select the Trust webcam as the default video and audio recording device in the configuration menu from the software you are trying to use the webcam with.
- For more information, please refer to software’s user information or contact the manufacturer for specific troubleshooting, which is usually available via the website of the manufacturer.
