Finnaly I managed to switch subwoofer on with hda_analyzer tool. Here exatct steps to make subwoofer on
Node[0x16] PIN - Output amplifier - Val[1] - unmute, check Widget Control - OUT Node[0x14] PIN - Check Widget Control -IN Node[0x0e] AUD_MIX - Input amplifier - Val[3] - unmute Node[0x0b] AUD_MIX - Input amplifier - Val[11] - unmute and set its slider approximately to the middle (this controls volume of subwoofer) All above make it to switch on. Node[0x0d] AUD_MIX - Input amplifier Val[3] - this checkbox amplifies suboofer and improve a little sound quality. I don't know how to make this adjustments to apply automatically as on system reboot everything restores back to the state of disabled suboofer But there is some problem still exist. As that as I noted soobwoofer sounds not actually as it suppose to be. It plays full range of frequencies and as I hear it parallelled to right channel. When I change balance to left it silence along with rigth channel. In Windows it plays only low frequences and sounds independently from front speakers' balance. I will continiue my attempts with that. Also there is a MusicNow application (analog of ExpressGate) which boots instantly and provides web surfing and music playing capabilities. It is based on Splashtop OS. This OS based on linux and it boots from Window partition.
