Thank you Januz. Amixer I think is works correct with terminal (now I does'nt look), but in future better to work hardware volume button my multimedia keyboard and my laptop computer (this hardware buttons works with prewious Ubuntu versions).
I think my problem produced a pulseaudio bug, now I going boot Karmic live cd to do requested tests. You wroted: "I also experienced very fast responsiveness while using Orca with Mozilla Firefox included in Karmic." Yes, I see this and I very happy when I see this quick response.
