With a vanilla kernel, it works perfectly with the pinctrl patch. In this case, I ran a cable from the wandboard over to my computer and recorded with audacity, using your wile true script above. Here you can see that with 4.11-rc5 plus the pinctrl patch, there is no channel swapping:
Which wandboard type do you have? mx6solo,dl or quad?
I am using imx6dl-wandboard.
I am surprised that the channel swap does not happen on your case. Maybe you need to run the test for an extended period of time?
Running on a quad.
On my case I usually get the swap in 1/10 of times. Max uses a Toradex MX6DL Colibri board and sees the swap in 3-4% of the times.
I'll run it for a much longer time and see what happens.
