David, tried your trick with snd-hda-tools. Headphones turned on, they are working perfectly, but in alsamixer they're still disabled. Moreover, i could not block speakers to isolate sound from them, so sound goes to them and to headphones simultaneously. Here is additional info: headphones turn off if i touch any of the following options in alsamixer (they all listed in playback): * front mic * line * CD (i don't have cd-rom) * mic * smart 5.1 - this option can only mute and unmute. In this case, sound in headphones can be restored only with snd-hda-tools. I'll attach my alsa info with working headphones just in case. PS: in windows 7 headphones are working, but automatic detection in front jack is corrupted. There i turned off detection and switch default output device between speakers and headphones.
