Looks strangely, but  vid=0x10573055 codec  is a software modem (as i know), 
At second attempt audiohd driver found ALC880 codec correctly . (vid=0x10ec0880)

JDS  shown mixer applet fine :) , but system doesn't produce any sound, gnome-sound-properties frozen after attempt to play test sounds. After it i found following  message on syslog:
--------------------------------------------------------------------------------------------------------------------------------
Jul 30 12:14:53 dp audiosup: [ID 243822 kern.warning] WARNING: audiohd0: start_play() failed to get play sample.
--------------------------------------------------------------------------------------------------------------------------------
Any ideas are greeted

Thanks,
Dmitry
