Changes since v1: - Fix according to Alexander's comments - A new patch has been added that removes dead code imported from Chrome OS. For easier reviewing, I will also send a total of the first three patches. Also note that the current routing logic are not optimal, e g, when on 2.1 speakers, plug headphones in, then unplug headphones again, the result might be that the stereo profile is selected instead of the expected 2.1 profile. This is not an error with this patch set but might limit its usefulness.
