Just wondering if any patches would come out soon for 3.12.x?
3.10.25 is getting rather old.

Hi Dave,
here you can find some inofficial sources ->

Do your patches support the lower sampling rates (like 8K) that were not working in 3.10? I was told in a post that those rates would be part of 3.12, but I don't think that happened. I also downloaded 3.18--there was absolutely no Wolfson card for Model B support in there as far as I could tell.

Did you read this -> http://www.element14.com/community/message/114712/l/re-pjsippjsua-with-wolfson-audio-card#114712 ?
Does it help?
What I'm looking for is this:

Hi Kenneth,
Both cards from a hardware perspective support the extended sample rates. This is available in the latest 3.12 kernel image and this supports both cards.
The table below gives specific details.
Audio Interface (AIF1) | |||
Parameter | Description | Typical Value | Units |
Supported Sample Rates | 8, 12, 16, 24, 32, 48, 96, 192, 11.025, 22.05, 44.1, 88.2, 176.4 |
| kHz |
Sample depth | Min bit depth of samples | 16 | bits |
Sample depth | Max bit depth of samples | 32 | bits |
Notes | The minimum supported sample rate is dependent on the SPDIF configuration. If the SPDIF Input or Output signal paths are enabled then the minimum sample rate will be 32kHz. |

Hope this helps,
Cheers

I tried to create georgpi's kernel according to his instructions, but I must have done something wrong, as it locked up and didn't reboot properly.
Which Pi version? Which linux image? Error messages on boot? Some more info, please. Otherwise I'm not able to help :-[
Best regards
Georg
Georg Mill--do you have a fully patched version available for download that I could try?
But maybe you better should read this ->
https://github.com/CirrusLogic/rpi-linux/wiki/Building-the-code
It seems that the 3.18 kernel is ready for the cirrus audio card AND rpi2 now. (we had to wait a looooong, loooong time for it)
Have fun.
So what exactly is https://blog.georgmill.de/wp-content/uploads/2015/02/linux-image-3.12.33-rt47-georg_3.12.33-rt47-georg-1_armhf.deb?
What do I do with it:
(1) put it on an SD card and use it to boot a model B?
(2) other?
I'm not very Linux savvy.
Head over to https://blog.georgmill.de/2015/02/18/update-for-wolfson-audio-card-on-raspberry-pi/ and following his instructions should get you up and running.
