HI! It's working for now! What I've done - Open file in console by command: sudo gedit /etc/modprobe.d/alsa-base.conf
and added to the end of file a line: options snd-hda-intel model="lg" Instruction finded here "http://help.ubuntu.ru/wiki/alsa" May be problem was caused by updating from Ubuntu10.10 instead of clean install OS. This string was persist in file(in Ubuntu 10.10- string was added manually) before update to Ubuntu 10.04 beta2, and after update OS - sound disappear. So I have been comment this line, reboot and nothing change, then I made this post. Today trying to help my self I uncomment this line, reboot and it help. It's seems to me everything is work.
