In some cases you might see that a webcam is not redirecting through the HDX Real-Time Feature in XenDesktop. This issue occurs if the web camera does not support switching to the default resolution of 352 x 288. It fails to be enumerated and redirect into the session as the Citrix HDX Webcam device.
I’ve not seen this issue with XenApp 6.5 FP1 yet, but I’ve seen it with some built-in webcams in different laptops.
So, here is how to fix it:
Configure the Citrix HDX Webcam device to switch to a value supported by the device. A common resolution for integrated cameras is 320 x 240.
Value Name: DefaultHeight
Data Type: REG_DWORD
Value (decimal): 240
