Video conference with presentation

[Tung]

I would like to do a presentation to a local and remote location. My question is how do I get the audio from the presentation to the remote location, and my local TV. I know the VGA does not carrier audio, so I have to use audio in from the VC400. If I do use the line in, will the mic pods still working.? Note, the remote locations have the same video conference system. VC400 with vc120 camera. Thank you for your help.
