Issue: Webcam and microphone not working in Connect meeting session. However if we use any other user (log in credentials to log in into the system) then it will start working which indicates system, microphone and webcam are working fine.
Reason: The reason can be the flash settings on the specific user. Below is the tag that helps us disabling the microphone and webcam from the system. This tag is stored in mms.cfg file on the location C:\Windows\System32\Macromed\Flash
AVHardwareDisable Lets you prevent SWF files from accessing webcams or microphones.
Resolution: Rename the mms.cfg file or remove the above mentioned entry from the file which disables AV to work.
