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

Some Toshiba laptops have another ALC268 codec on slot#3 that conflicts with the primary codec. The codec#3 is for the digital I/O, and should be fixed by the driver, but it'd need a bunch of changes.
So, let's fix the probe problem temporarily by setting the default probe_mask value.
