I installed this on my fedora 13 (x86_64), but it does not record any voice. I installed the 64-bit plugin RPM from here: http://www.google.com/chat/video/download.html. The plugin was installed and Firefox restarted. I have verified that the plugin is enabled and shows up under about:plugins.
Additionally I also tried it earlier through Windows XP under virtualBox. In bot cases I did verify that my microphone was recognized by Windows and Fedora, by using the voice recorder on those systems.
I can dial, hear the dial tone as well as the other party when he/she answers. I've done a Google search and this seems to be a common problem. My Microphone and headset is a Sound Blaster Areana Surround USB. When I go to gmail/settings/chat it does not recognize the sounds. Here is one of the pages I checked: http://www.google.ru/support/forum/p/chat/thread?tid=0894d226c6a04f35&hl...
