Done, but I'm now seeing some type conflict errors when building my userspace 
tools (i.e. after moving to include uapi/sound/asound.h from sound/asound.h).

e.g.

#include <stdlib.h>
#include <uapi/sound/asound.h>

int main ()
{
}

gives :-

gcc uapi-test.c -I ~/source/linux.git/include

                  from uapi-test.c:2:

etc.....

I'm guessing here you have this building already with uapi alsa-lib ? Although 
I cant see any alsa-lib changes in git to use the new header.

Thanks
