I'm still on.
And while testing WM9712 its touchpad interface, connecting a 800x600
display (instead of the default 640x480 one) results in a gone sound and
input-device - pretty queer:
WM9711/WM9712 SoC Audio Codec 0.4
asoc: platform pcm constructor failed
asoc: can't create pcm HiFi
asoc: failed to instantiate card PhyCORE-ac97-audio: -12
I have to admit that I used this time a 3.2 kernel. I'll test with
current later these days.
