Thanks for the patches.  They are all well formatted now.

I applied your patches except for 17, 
	ALSA: HDA VIA: Add 2nd S/PDIF out for VT1708S and VT1702
as Robert reported a regression.

This is likely because of the behavior change by this patch.  Now
the second SPDIF has to be specified manually with the explicit
substream number.  This itself is fine, but I see the problem with
pulseaudio, for example.  There is no good way to specify this substream
automatically for PA with some symbols like "spdif" or "hdmi".

This is basically a problem of the current ALSA core and HD-audio core
implementation.  So, we should solve all together.

On most machines, it's not too big deal to have it the secondary digital
as a slave.  If this really matters, we can add another hint to make
the individual digital substreams conditionally.

Anyway, please check the latest sound GIT tree (or alsa-driver snapshot)
whether it works.  I only tested the compilation, so far.
