Yes, there will, but the nature of the changes are yet to be determined.
 The mixer extensions specify different control types (toggles, enums,
sliders, etc.) for exporting audio hardware (and purely software)
controls to userland.  E.g., a driver may export channel routings of
front, rear, and front+rear as MIXT_ENUM, leaving it to the user to pick
a routing.

Since classes just resumed, I have some homework to take care of first (
:P ), but I'll try to take a look at it tonight or tomorrow.
