It appears the camera and microphone controls have been deprecated, as they are no longer in the list of controls, and existing controls are no longer working.
Please notify the community before deprecating controls that are being used by customers.
I think this was a misunderstanding. Not all controls are listed under Controls, media and sound controls are under Media on the ribbon.
Perumal helped me find the controls. I was looking under controls when they are under media. So cancel this ask please (can't delete it).
