OK, it's a bug in Nvidia HDMI patch.  Fixed now on sound.git tree.

You should check my sound.git tree to get the very latest version.
    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git

The master branch is for the currently developed kernel, i.e. 2.6.28.
The devel branch is for the previous one, 2.6.27.  For tracking the
development, just check one of them.

The real patches are usually committed into topic branches like
topic/hda.  These are merged into appropriate branches.
