Hi Bela

Sorry for the delay, but I have just started with looking into the wolfson card and kernel 3.17.1.

I have tried to load the needed modules, however, there seems to missing "arizona-spi" at least piCore complains that this module is not found in modules.dep. All the other modules needed for the wolfson card are there.

Maybe that is the reason for not being able to see the wolfson card using aplay -l.

I just noticed that you have updated to 3.17.2 - I'm not sure if support for the wolfson card has been removed from this version?
When looking at the commits at the raspberry github for 3.17.2 I can't find any info on the wolfson pull request.

regards
Steen

bmarkus:
Same in 3.17.2 It can be a kernel configuration issue. I have enabled all sound soc related modules, but there can be a problem with one of the Kconfigs in kernel source with dependencies. Made a fast search in kernel source but didn't find this module, but maybe I was not careful enough. Look around in kernel source.

BTW, which module is claiming for missing arizona-spi ?

bmarkus:
Found, it is in drivers/mfd

I will upload the new alpha510 with 3.17.2 and corrected alsa modules later today and PM when ready
