Hi all, We have set up a 2 computer accessgrid using Windows(Display) and FC4 Linux (Audio/Video Capture). We have used the AG2.4 toolkit. Right now we are in the NCSA Lobby via the AG connector (good stuff!). The problem is that we can see and hear everyone, but we cannot talk. Attached some screenshots here. Does anybody have any ideas of what could be causing this, and a suggested fix? (The gain for talk is probably too high, but that's only because RAT is not responsive to the audio input at all.) Thanks, Sherri Li School of Interactive Arts and Technology Simon Fraser University Surrey The only way to discover the limits of the possible is to go beyond them into the impossible. - Arthur C.
