Hi. Some days ago I installed F16. Downloaded Java, Opera, Clementine and Flash Player. The problem is that I can't hear anything from my speakers unthil i plug in the headphones. After that the speakers play well. After unplugging headphones, the speakers again are muted. IMO it should be other way - if headphones are plugged in, then mute speakers. But it is: if headphones are plugged in, then unmute speakers. Does anyone know what to do with this?
