This application  BY DEFAULT  changed my volume from MUTE to an exceptionally loud volume and broadcasted some very misunderstandable conversation. THIS IS NOT ACCEPTABLE BEHAVIOR FOR A VOIP CLIENT TO DO BY DEFAULT. Mumble is about privacy and security  and not only that  I felt that changing my volume was a violation of my wishes as the user. I had not changed any settings in your application  this happened automatically. Please change this behavior  I don't know if it's a bug  or what... but I am no longer a happy user of your application. How can I trust that this won't happen again?
