The Citrix HDX webcam shows no video when used inside of Google Chrome or Microsoft Teams. It only displays a black screen. If switched to a generic USB channel it functions, but that is not ideal for WAN scenarios. If tested with simple webcam software, the HDX version displays properly, but still does not work in IE/Chrome.

Webcam redirection is not supported in 64-bit applications with XenApp / XenDesktop 7.16 or older. This was fixed on 7.17 and Receiver 4.11 for Windows.

Also, note downloading Google Chrome and installing - you may note that the application appears in the folder:

C:\Program Files (x86)\Google\Chrome\Application

Which would normally indicate that application is 32bit; however, checking Task manager displays as 64bit application:
