Thanks.  Nothing jumps out at me.

Is there always trouble, or only when docked or after a suspend/resume
cycle?  Can you hear sound through headphones?  Does fiddling with any
of the knobs in alsamixer help?  (You may have to press F6 first to
make sure you are setting the controls for the ALSA device rather than

Like the rest of the codecs, the sigmatel code has had some work done
upstream recently, so if you get a chance to try v3.3-rc2 or later,
that would also be useful.

It works like this:

 1. Grab a copy of the source:

	git clone \
	cd linux

    Or if you already have a copy, update it:

	cd linux
	git fetch origin

 2. Check out Linus's "master" branch:

	git checkout origin/master

 3. Configure:

	cp /boot/config-$(uname -r) .config; # stock configuration
	make localmodconfig; # optional: minimize configuration

 4. Build and test:

	make deb-pkg; # optionally with -j<n> for parallel build
	dpkg -i ../<name of package>

If it fails in the same way, please report upstream to
alsa-devel@alsa-project.org, cc-ing linux-kernel@vger.kernel.org,
Takashi Iwai <tiwai@suse.de>, and either me or this bug log so we can
track it.  Be sure to mention:

 - steps to reproduce the problem
 - symptoms, how they compare to what you expected, and how that
   indicates a problem (should be simple here)
 - which kernel versions you tested
 - alsa-info.sh output, as attachment or link
 - any other weird symptoms
 - a link to this bug log for the full story

On the other hand if it doesn't fail, we can try to figure out what
patch fixed it.
