It would also be great to hear from anyone using a Wolfson audio card, ie. whether it's working or not.

I had a quick look at it, but didn't get very far.

A fresh installation without any additional config shows these modules loaded - question: where do they come from, some device tree config?

Code:

Module                  Size  Used by
arizona_ldo1            2335  0
fixed                   1425  0
arizona_spi             1109  0
snd_soc_wm8804          7092  0
snd_soc_bcm2708_i2s     5585  0
snd_soc_pcm512x_i2c     1481  0

regmap_mmio             2181  1 snd_soc_bcm2708_i2s
snd_soc_core          104264  4 snd_soc_pcm512x,snd_soc_wm8804,snd_soc_tas5713,snd_soc_bcm2708_i2s
snd_compress            7084  1 snd_soc_core
snd_pcm_dmaengine       2935  1 snd_soc_core
snd_pcm                63094  3 snd_soc_wm8804,snd_soc_core,snd_pcm_dmaengine
snd_timer              17712  1 snd_pcm
snd                    41549  4 snd_soc_core,snd_timer,snd_pcm,snd_compress
lirc_rpi                6008  3
lirc_dev                7885  1 lirc_rpi
rc_core                16223  1 lirc_dev
bcm2708_rng              812  0

One thing to note is that it's a good idea to either blacklist lirc_rpi or set it's gpios to 14/15 - otherwise it'll conflict with the wolfson card.

After some tests with minor success I tried disabling a few modules which I though maybe could conflict with the wolfson drivers (not sure, though, will have to check later):

Code:

blacklist lirc_rpi
blacklist lirc_dev
blacklist snd_soc_pcm512x
blacklist snd_soc_pcm512x_i2c
blacklist snd_soc_tas5713
blacklist snd_soc_wm8804

And enabled these modules:

Code:

arizona_i2c
gpio-arizona
extcon-arizona

snd-soc-wm5102
snd-soc-pcm5102a

snd-soc-wm-adsp
snd-soc-rpi-wsp

This lead to the following lsmod:

Code:

And this dmesg: http://sprunge.us/QGHi

"Failed to allocate IRQs" certainly doesn't look OK - but at least the voltage warnings are only temporarily at the beginning. Edit: but the "fixed" (fixed voltage regulator) module usage count seems to be strange.

Edit #2: here's /proc/interrupts:

Code:

Another try, without blacklisting snd_soc_wm8804 gives this modules:

Now I'm stuck. Any ideas what I might be missing?

so long,
