I am running Skype on DEBIAN Wheezy with Gnome 3.0. If I use Skype normally, I have sound from Skype but the microphone is apparently muted. If I open "gnome-control-center sound" (right-click on volume control icon and select preferences) and then start a call, the microphone works correctly in Skype. Starting pavucontrol from the command line and leaving it open has the same effect. I do not have to change any settings, just have a sound preferences (not SKYPE preferences) window open. This works even if the window is minimized. Here is the sequence: 1. Start Skype 2. Start a Skype test call 3. Can hear sound, but mike seems muted. 4. End call 5. start "gnome-control-center sound" (use 'ps aux' to see it). 6. Start Skype test call 7. Everything works 8. End call The important thing is the "gnome-control-center sound" is running when the call is initiated. So the easy work-around is just to start it when I start my session and minimize it, then everything works. I would like to avoid have to do that. Any suggestions about where to start looking for a solution are welcome. Bill West --
