I installed Mumble on 3 of my computers today. I installed the server on my laptop at first. When I tested it out, I could hear myself coming through my son's PC speakers when I was talking on my main PC across the room. I had to put in the IP address of the computer that was running the server to connect to it. Thinking I had figured things out, I decided to install the Mumble server on my file server PC since it is hardwired to the network. I then connected all the PCs to that Mumble server, and although I can see the users are all connected, no one can hear me when I'm talking. Any ideas?
