--- Comment #13 from Marta Löfstedt <marta.lofstedt at intel.com> ---
For more information on the patch I reverted. The patch introduce a potential
200ms busy-wait when interrupts are turned off. Also, if the state isn't
updated with-in those 200 ms, nothing is done. 
I believe this patch should be rewritten by audio developers.
