I see no relevant commits regarding HD-audio (at least for ALC889) between these two points except for "Make converter setups sticky". And, the fact that /dev/audio works implies that the PCM stream works basically. So, I have no idea for now. It might be outside the sound stack. I'll try the latest tree on my machine whether I can reproduce the problem. thanks, Takashi
