Cirrus Logic Audio Card working on the Raspberry Pi 2

Hi, I followed the building instructions on github and replaced the kernel in Ubuntu https://ubuntu-mate.community/t/ubuntu-mate-15-04-for-raspberry-pi-2/517/101

Now I would like to stream the spdif input directly to my speakers (analog or via USB sound card)

I tried to test spdif capturing with the sh skript, but only got a mute audio file.

Is it normal that pulseaudio only recognizes the analog output but not the inputs of the cirrus card?

I made a couple of scripts to route sound directly on the Wolfson card. I think they work on the Cirrus card too.

One of them connects S/PDIF In to Line Out.

No idea at all, I've never used pulseaudio. Have you tried recording without using pulse?

Hi Ragnar,

I'm a bit confused I'm afraid! I saw your .deb files and tried to install the drivers with these .deb file. The package was installed, but thats obviously not enough to get the card working. So could you tell us the steps to follow to get the card working? Do i also need the .tar files? Please forgive me if this is a stupid question. The method with the .tar files only worked for me perfectly.

Thanks for your great work!

Hi Thomas!

No, you don't need the .tar file, but you have to make the same kind of changes to the configuration files.

After you have installed  the .deb package, add these lines

dtparam=spi=on
dtparam=i2c_arm=on
dtoverlay=rpi-cirrus-wm5102-overlay

to the file /boot/config.txt

On a RPi2B, also add

kernel=vmlinuz-3.18.9-v7cludlmmapfll

or, on all others, add

kernel=vmlinuz-3.18.9cludlmmapfll

to /boot/config.txt

Put these lines into /etc/modprobe.d/raspi-blacklist.conf  (create the file if it doesn't exist.)

softdep arizona-spi pre: arizona-ldo1
softdep spi-bcm2708 pre: fixed

EDIT to add: You  also need the overlay file rpi-cirrus-wm5102-overlay.dtb if you don't already have it in /boot/overlays. You can extract the tar file in some temporary location and then copy the overlay file from it to /boot/overlays.

Hi Ragnar,

that was the missing part! It's running now!

Thanks for the good work and your kind support!
