While poking through the registry trying to find a way disable Automatic Gain Control (AGC) for Polycom RealPresence Desktop (version 3.3.0.50871) video conferencing software, I stumbled upon a different registry key that addresses another annoying problem and that is to keep RPD from minimizing itself to the taskbar. Low and behold, it doesn’t appear that there is a setting associated with this registry key inside the program to disable this functionality either.

As a side note, I did have to open a support request with Polycom over the AGC issue as it automatically takes over the audio recording interface even after disabling all of Windows control over the settings and it negatively impacts conference quality. Because the software automatically dials down the input level of the recording interface, the user then has to yell just to be heard, which only further possibly causes the input level to go down even more, without ever adjusting the audio level back up. Currently, there is no way to turn this off, so it will probably end up as a feature request for the next software release.
