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

Subject: [PATCH] ALSA: hda - Add probe_mask default for Toshiba laptop with ALC268
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.
