So this morning I went into a mumble server that I normally go into and I find that I can't hear anyone. When I spoke to them through the mic, they all told me that they heard me. One solution that I tried was to reconfigure the audio using the audio wizard. The first test that comes up is supposed to have a sample voice, but I heard nothing. This problem most likely occured last night when I forgot to turn mumble off, and my mother was using the computer. She didn't know what was going on so she restarted the computer. I don't really know if that is the problem. Thanks.
