I am new to second life. When I walk around I can sometimes hear voices talking (sounds like other users chatting with each other, or music playing. This is not like when I go to a place that has music playing (e.g. I went to an Alice In Wonderland themed place and it had background music). I even hear the voices when I am on an island which has no other people on it. This fades in and out randomly. I have tried turning off sound completely with the icon in the top right. I have also tried going to preferences, Sound & Media and unticking Steaming music, media and voice chat. Still I hear the voices and music every now and then. Turning sound off stops background noises like the sea, streams, birds etc but not these voices. I know they are something to do with second life, not another program on the PC, because the people mention second life. Please help because this is driving me crazy!!!!!!!!
