Thanks for reporting it.  Can you test with Takashi Iwai's for-next
branch?  It works like this:

 0. Prerequisites:

	apt-get install git build-essential

 1. Get the kernel source tree, if you don't already have a copy
    with history.

	git clone \
	  git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

 2. Retrieve the sound tree:

	cd linux
	git remote add -f sound \
	  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

 3. Check out the for-next branch and test.

	git checkout sound/for-next
	cp /boot/config-$(uname -r) .config; # current configuration
	make localmodconfig; # optional: minimize configuration
	make deb-pkg; # optionally with -j<num> for parallel build
	dpkg -i ../<name of package>
	reboot

Please also attach output from "alsa-info.sh --no-upload" on an
affected and an unaffected kernel, so we can get to know your
sound card better.  The alsa-info.sh script can be found at [1].

Sincerely,
Jonathan
