The DeviceID patch for LynxPoint HDA was already included in kernel 3.5. Beyond that, more patches to enable HDMI and DP audio are WIP.
These three patches have been accepted in alsa upstream now: git.alsa- project. org/?p= alsa-kmirror. git;a=commitdif f;h=cb192625233 496ac3d96cce667 ebf4e322dab678

this patch add proper id for Haswell HDA Controller.
2. http:// git.alsa- project. org/?p= alsa-kmirror. git;a=commitdif f;h=e269cee227a 2b2297b79bfc710 94c709b9387061
0x80862807 is HDMI id for Haswell HDA.

This works for HDMI audio, otherwise there's blocking issue.
