I'm a complete newbie in linux, so I already feel bad for what I'm going to ask ...
You once said in this forum ...

Open Mplayer, Right click on screen, select Audio, choose alsa, Select Video x11, close
When Mplayer opens in Firefox to view streaming video, audio, you "might" have to repeat the process.
My problem also started with "Error opening/initializing the selected video_out (-vo) device" when trying to run a *.avi movie with the Mplayer. However, now that I changed some stuff in the Mplayer according to your hint, I get "Could not open/initialize audio device -> no sound." Indeed, I can't hear a thing anymore. Even the videos on youtube have become quiet. Amarok doesn't want to start anymore and the Totem Movie Player has to be closed by brute force (this I noticed for the first time when I wanted to run the *.avi file mentioned above ... meanwhile Mplayer is my default *.avi player). The thing is that initially things seemed to work fine (the Mplayer plugin, *.mp4 movies, sound with Amarok, it was OK).
I have a Dell Inspiron 6000, in case that helps.
Could you or, of course, anybody else help me out here
