I cannot get any audio from Firefox in any format (Flash, .wma, mp3, online radio, etc). I have tried the suggestions on the help page concerning the volume mixer, updating flash, etc. I did notice that Firefox and the Plug-in container do not even show in the volume mixer. Windows Media Player stopped working on this computer not long after I got it, that is not a real concern though. Itunes plays just fine. I am using Vista Home Premium SP2. Any suggestions?
