Right, it's no good solution as you expected ;)
The problem is that your patch will disable the all HDMI devices that are
newly supported on 2.6.29.

Is your machine Toshiba X200, found in bug 12735 ??
	http://bugzilla.kernel.org/show_bug.cgi?id=12735

If yes, could you try the patch below?

Also, it'd be helpful if you can try sound git tree (master branch):
    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
that contains the very latest driver.  This should work as is.


thanks,

Takashi
