It will be created on demand when sound application will try to open it 
directly. Also it may be set as default with hw.snd.default_unit sysctl 
described in man sound.

Indeed. First one is HDMI on video and second on motherboard. The old

work better. It could be ported to 7-STABLE without any modifications.
