Whatever works!  Though I can't make a plausible connection of how
those two facts lead to sound for you.  :-)

It's been awhile since I monitored alsa closely, but then ICH9 was the
cutting edge.  Probably ICH12 is now. :-)

Lots of opinions there.  And as you can see from the comments, there
are as many viewpoints about sound in linux as there are users of sound
in linux.  The trouble is that sound is a desktop function, and the
money is all made in servers.  So how likely is it that sound will get
the resources?  ;-)

Given modern hardware and changes in the kernel I don't know that alsa
is the best way to do sound in linux, but it is the most comprehensive
and complete right now, and as it exists in linux serves my purposes,
so I don't worry too much about those deep architectural issues.
