Suddenly, I can't talk in SL. This is the first time I experience this problem. I use the same headset, I hear streaming music and other avatars speaking, and I see the white dote over the head, but when I click the talk buttom, the waves doesn't appear, and other avatars can't hear me. I use the same headset for Skype and Audacity with out any problem, and before I had no problems talking i SL. Please help, Yann Soz
