It looks like the RPi has lost the connection to the Wolfson card.
Does any of the other scripts run without error messages?
Post the output of these commands:

all I got was this as a result:
amixer: Cannot find the given element from control hw:0 (but the same thing for 11 lines)
There was a thread about the same error message (on running './Playback_to_Headset.sh') back in March
Yep, and that turned out to be a broken Wolfson card.
Oh how odd. It was working fine before with the official wolfson image. I just couldn't expand the filesystem to the entire 16gb card. I will have to retry the official image when I have time later... ugh I hate wearing down flash storage.
Although I must add something regarding the contact of the p5 connections on the wolfson card. This seems challenging considering there is soldering on the audio card above the blue RPI 3.5 mm audio jack that protrudes, preventing the audio card to fit easily. Could this be the culprit?
On the other hand I saw that someone performed an rpi-update, like myself. This could be the issue.

Well, one guy reckoned it was a faulty card, another said the problem occurred after doing an 'rpi-update'
I don't see how one would not perform an rpi-update in order to install the required software to playback audio files. In other words, if I don't perform an update and try to install VLC, I get a bunch of error messages suggesting I run an rpi-update.
I considered the possibility that between the time I flashed the Wolfson image and yours, my card broke. I tried the original again and everything works fine. Which is great because I know my card is not broken. But I still can't get the one from this forum to work. I guess I'll wait for default raspbian driver support?
Does it really suggest you should run rpi-update?
Before trying to install the player applications you should run "sudo apt-get update".
That command doesn't actually update any applications, it just makes sure the list of packages from all repositories is up to date.
I.e. it makes sure a subsequent "sudo apt-get install xxx" will find the xxx application out there on the Internet.
rpi-update is another beast altogether. It updates everything to the very latest bleeding-edge version, including firmware and kernel. It should be used with caution, because it may install experimental code.
it is still an issue here, but solved by using funzip | dd to do the copy, if anyone else is looking for a solution now.
something is wrong with the file, maybe it has been truncated or so, but the error is right at the end, after the end of the useful part of the file. funzip complains but has already done the unzipping, other programs bailed when they found the error without leaving the output ready to use.
Has anyone tried to get the Wolfson audio card running with the newest stable kernel (3.12.26)?
I'm trying to use the camera module together with the Wolfson audio at the same time and the old kernel had some problems with the viewing area of the camera. I tried to compile the new kernel by myself and include the patches from Wolfson which they provided for the old version. The new kernel is running, the camera problems are gone and the sound card is also listed when I call "arecord -l". Unfortunately it won't record a thing so I fear I missed something during the patches.
Hi foaks, im new here,
Bought the wolfson pi sound car yesterday and tried to update the kernel in raspbmc but well failed quite hard so i tried again and well got raspbmc starting again but still the sound card not working.
Now i flashed the build from wolfson on the card (yeah i unzipped it with a mac the program"The Unarchiver" did the trick, got the same error with mac his own unarchiver so if you are looking for that here you got it!
Now im trying to install xbmc on this build, seems like to be going well until now! (not finished yet).
If someone is interested in XBMC running with the wolfson pi and i get it to work i can upload the img somewhere for you so let me know
works for Linux (p7zip)
7z e wolfson_3.10_master.zip
The File should be called wolfson_3.10_master.7zip XD
I would like to have that image very much.
Can you provide a download link?
I have an idea I want to try out - replacing a hearing loop with streaming audio over WiFi.
(Hearing loops use a magnetic field, which cause interference on any unbalanced input).
I found this article which suggests using a Raspberry Pi with an external sound card http://www.crazy-audio.com/projects/raspberry-pi-for-audio-distribution/
I have bought a Wolfson card and plan to use the Raspian image plus your modified kernel.
e.g. simply turn on and it should boot / start broadcasting the Audio from our Sound system mixing desk digital out.
Users would simply use headphones with their tablets / smart phone / ipod.
Just not very certain on how to modify the example in the article to use the SPDIF input. Any suggestions or problems to look out for?
My other concern is shutting down the Raspberry Pi.
Are there GPIO pins available on the Wolson Board?
The PDF suggests that GPIO 4 and 3 are on pins 15 and 16 of the feature header. I am thinking of a simple push button to send a shutdown command.
Reading this thread has been very helpful.
Thank you Ragnar! The original image seemed to work, but the network was unstable and broke down before I could install anything. I also did not understand why they wasted so much place using NOOBS as a base for it, and unzipping directly to dd did not work because of a problem with archive. If they have not done so already, I do not understand why they have not asked you whether they could offer your version to download instead or at least include a link to it to make it easier to find.
I also find it quite ridiculous that the driver is still not officially included in the kernel, but I understand that the person originally working on that is not any more and the new guy probably needs some time to get into it [https://github.com/raspberrypi/linux/pull/705#issuecomment-61638834].
I deleted my original zip download and the img of the above file. I have downloaded it again, but all the unzip programs I try will not unzip it, ( say no unzip sig).
I have painfully downloaded it again and still no joy with unzipping.
Have you changed the file recently?
Please, please publish the md5 sum for this file! (so I can eliminate download errors)
