What do you mean "breaking voice"? Please be more specific.
Run alsa-info.sh with --no-upload option, and attach the generated file. This will contain the detailed hardware information. The script is found at http://www.alsa-project.org/alsa-info.sh
Is this a regression from the older kernel? If yes, please run alsa-info on both working and non-working kernels and attach the both outputs. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
Also, try the latest sound git tree whether the problem persists on the latest version.
You can find some other information on ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.pdf
