there are configure options to specify the header files for
alsa-kernel. one is --with-kernel and another is --with-soundbase.
the former specifies the top path of 2.6 kernel source tree, and the
header files in that tree will be used. the latter specifies directly
the path of alsa-driver's include directory.
for example,
./configure --with-kernel=/my/src/linux-2.6.0-test9
./configure --with-soundbase=/somewhere/alsa-driver-1.0.0/include
when no these options are given, the standard path,
i.e. /usr/include/sound will be searched.
these options are necessary only for (some of) alsa-tools. usually,
applications don't need (and shouldn't) access to the kernel header
files.
