If I may suggest - please make this function available for the Axx series as well. Do you need to recompile the driver module(s) or can it be done by a kernel switch?
I think the number of people using the 1 or 2 very specific earphones that actually work with this noise cancellation is minuscule. If we can improve the sound/save device memory/battery/clock cycles I'm all in for disabling useless functions - or at least having the option to disable them.
As the smaller players will get only the WM1A/Z-based firmware, noise cancelling features will not be available anyways, so this option will be present.
