The write will be suppresed if the register contents don't change which looks like what you're seeing here -quoted
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
When I do decrease from 800x600 to 800x594, wm9712 works. Any ideas?
