Can you imagine why the registers don't change?
I can't immediately think of any reason, no - I'd step through or annotate the code and have a look.
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.
Same behaviour with 3.4.0-rc6:
Framebuffer driver mx3fb configured for a 800x600 display:
soc-audio soc-audio: ASoC machine PhyCORE-ac97-audio should use snd_soc_register_card() asoc: platform pcm constructor failed asoc: can't create pcm HiFi :-12 asoc: failed to instantiate card PhyCORE-ac97-audio: -12
mx3fb configured for a 640x480 display: soc-audio soc-audio: ASoC machine PhyCORE-ac97-audio should use snd_soc_register_card() asoc: wm9712-hifi <-> imx-ssi.0 mapping ok
