The best way to check whether your snapshot tarball is the latest one
is to see alsa-driver*/HEAD and alsa-driver*/alsa-kernel/HEAD files.
The former corresponds to alsa-driver-build-unstable.git tree, and
the latter to sound-unstable-2.6.git tree.  On web, you can check via
the following URLs:
    http://git.kernel.org/?p=linux/kernel/git/tiwai/alsa-driver-build-unstable.git;a=summary
    http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-unstable-2.6.git;a=summary
Click the top commit entry and compare the commit id there and one in
your HEAD file in the snapshot tarball.

For example, the latest snapshot I uploaded now has alsa-kernel/HEAD:
    a3e1ef74a8ec8b6e3c30f7aa06c5d5d2f2bea7a9 Merge branch 'topic/sbxfi'
