Hello, Ron Johnson & Nigel Henry & Andrei Popescu & Star Liu. Thank you 
very much for sound that has begun to work yet.
I have include myself to 'audio' group, install 'alsa-utils' package (with dependencies and recommends) (while configuring them in Debconf, I select ALSA system). Then I ran 'alsamixer' where unmute sound. After it sound began to work.
P.S. I decided not to configure ALSA with 'alsaconf' because I have not very old kernel. Please, correct me if I have done something bad.
