Cirrus Logic Audio Card and Raspberry Pi 3

Hello Juri,

I experienced the same problem with Pi 3, step 1. I did not try step 2. Even though, I noticed that the Download file on this website has been recently updated, the UI looks different. The Cirrus Logic Audio card and this software works on Pi 1 Model A+ board. I also tested the previous ver of the OS on Pi 2 Model B and also worked great.

Hopefully, the manufacturer will release a new embedded OS that works with Pi 3.

It works just fine with the Pi3. Just load raspbian jessie, run rpi-update to make sure you have up-to-date firmware, and follow the instructions on how to build your own kernel: https://www.raspberrypi.org/documentation/linux/kernel/building.md 

The repo with the cirrus drivers is https://github.com/HiassofT/rpi-linux.

Here is proof that it works:

Hi Alan!

I got my card to show up finally. Hitting the hay for now but check out this entire thread and my posts: Re: Driver fixes and updates to kernel 3.18.16 and 4.0.5

it might get you on the right track. I didn't use NOOBS, just imaged an SD card with rasbian jessie 3.18.16 I think, the latest one. Yeah, I think really accurately documenting everything I did to get it to work in layman's terms will help a lot. I will chime in more tomorrow.

Cheers,

Eric

Hi Eric / Alan,

Following along here.  I'm working through this process as well.  Alan, I've gone the NOOBS way and followed the tutorial on GitHub (https://github.com/CirrusLogic/rpi-linux/wiki/Building-the-code, but my first run hasn't yet been successful.

Eric, congrats on getting the device working!  I see you went with a diff OS version than what NOOBS installs.    I'm now reading through your Driver fixes link, however, the gaps of my knowledge are many, so I'm tagging along and hoping I can piece together a functioning system. 

Happy to post a complete tutorial as well, should I get this working.  Current state of being:

Actually, I think I've got it working by following the instructions here RPi Linux driver for Wolfson / Cirrus Logic Audio Card

I started at "Pre-compiled kernels' w/ a wget for the latest and seems like we're cooking.

Jeff that's brilliant!

Which kernel did you go with- the 4.1.x or the 4.4.x?

Kind regards

Alan

Okay so where I am now:

I have the new kernel in and running; uname -a reports 4.1.19-v7+ with the correct date of 11th March 2016

I've added the 2 lines  in /boot/config.txt

I created the module dependencies file /etc/modprobe.d/cirrus.conf with the 3 softdep lines in

I created the directory bin in home/pi and wget'd and extracted the usecase scripts to there

on reboot,

I have no audio capture devices and only the default on board play device,

Attempting to run one of the usecase scripts results in:

mixer: Control hw:sndrpiwsp open error: no such device

I've checked the config file entries and they look okay, I looked in /var/log/syslog and can't see anything there that seems relevant... :/

any suggestions?

Kind regards,

Alan

Thanks Alan, I'm running 4.4.x

Here are my steps, which were more brute force than specific:

1) wget http://www.horus.com/~hias/tmp/cirrus/cirrus-linux-4.4.6.tgz

2) sudo tar zxf cirrus-linux-4.4.6.tgz -C /

3) Follow Configuration through Setup module dependencies (+ I've updated my GPU firmware was also listed later in the tutorial) from this site:

RPi Linux driver for Wolfson / Cirrus Logic Audio Card 

Before this, I had started the SD card with the NOOBS installation of Raspbian.

I switched to the 4.4.6 kernel, BUT I did discover a typo in one of the config file lines- which just goes to show, however well you think you might already have done it, check and check again. It doesn't help that the text on the Pi graphical UI is a bit hard to read on occasions.

Here is my detailed step-by-step procedure.

Pre-requisites: RPi 3 with Cirrus Board installed and connected to network (wifi is fine).  I'm using a Samsung tv as the monitor and Dell USB keyboard and mouse.

Plug in the SD card with the NOOBS distro from Element 14 and boot up the RPi, following the instructions on screen. I didn't need to expand the file system as it was already done.

Getting the kernel and usecase scripts:

In Epiphany browser, download the 4.4.6 kernel from here:

http://www.horus.com/~hias/cirrus-driver.html

And download the usecase scripts from here while you're at it:

http://www.horus.com/~hias/tmp/cirrus/usecase-scripts.tgz

Configuration:

Open the file /boot/config.txt- I use the command line Nano but any file editor that you can open with root privileges will do:

sudo nano /boot/config.txt

I added the lines:

#This enables the Cirrus Logic driver and adds ALSA plugin support

dtoverlay=rpi-cirrus-wm5102

dtoverlay=i2s-mmap

Then hit Ctrl-O and Enter to save, and Ctrl-X to exit Nano

Then create the file /etc/modprobe.d/cirrus.conf:

sudo nano /etc/modprobe.d/cirrus.conf

Enter the lines:

softdep arizona-spi pre: arizona-ldo1

softdep spi-bcm2708 pre: fixed

softdep spi-bcm2835 pre: fixed

And again, Ctrl-O, Enter and then Ctrl-X

Create a bin directory in your home directory:

mkdir bin

Now un-tar the usecase scripts to this, either using the graphical x-archive or command line; it doesn't matter.

cd to the bin directory and verify the scripts are there.

Kernel installation:

Finally, cd to your Downloads folder and install the kernel:

sudo tar zxf cirrus-linux-4.4.6.tgz -C /

And now the big moment! Reboot.

Notice the two bright LEDs on the Cirrus Logic card.

If your driver installation has succeeded, you will see the red LED flash and then go out during the boot up sequence.

You can further confirm success by typing

aplay -l to list playback devices; you should see two- card 0 which is the onboard one, and card 1 which is the Cirrus

arecord -l to list record (capture) devices. You should see just one- card 1, which is the Cirrus.

Conclusion:

I'm now going to install OpenOB which is the whole reason I'm doing this!

I sincerely hope this helps to get anyone else up and running

This works great, thanks for the description.

Dekrispator is a nice little synthesizer that you may want to try. A precompiled binary for Raspberry Pi is included.

You can just start it and listen to pretty sounds that randomly change over time. In addition, you can hook up Midi devices:

Midi keyboard and Midi mixer. Once you hit the first key on the Midi keyboard, the randomizer stops and you keep playing

with the current sound. I ported the synth from STM32F4 to Linux/Mac/OSX/rPI using STK libraries.

I wanted to thank you for your guidance. I brought the Cirrus Logic card and followed your instructions and it worked first time with PI3, Noobs and 32 GB HD video class 10 Sandisk. I have now managed to use it like a cassette recorder with HiFi level quality.

Following on from when the install is completed here is some further guidance.

In terminal run the following scripts ( which must be run every time the PI is booted to connect the Cirrus Logic Audio input and output ):-

Record_from_DMIC.sh

Playback_to_Headset.sh

Now the Cirrus Logic card is operational. It works even though the speaker in the top bar shows muted audio. If you start LM Music this also shows the speaker muted with a X but the Cirrus Logic card output to headset is working.

You can download the HD_Audio test tracks provided with the Wolfson card for the old Raspberrypi A and B. They are in the download section on the element 14 website. Before they will play with LXMusic you must install the FLAC plug in. To do the use Add and Remove Software and search for XMMS2.

Select xmms2 – all plugings and install.

Now if you add the tracks to the LXMusic play list, plug in your head phones (black socket) and press play you will hear the music.

Recording is difficult using the terminal commands, but the Cirrus Logic card works like a dream with the Graphic User Interface provided by Audacity. Use Add and Remove Software, search for Audacity and install.

Start Audacity and click on the record button and speak close to the cirrus card on board microphones. The sound wave form will appear in the window. Press stop. Press the play button and your voice will appear in the headphones.

I have managed to record CD quality 44.1KHz, Video quality sound at 48 KHz both at 16 bits. The Pi also works at 24 bits 96 Khz and 196 Khz recording from the on board mics.

The CD and Video was captured from the SPDIF to do this you will need to reset the card in the terminal window.

Reset_paths.sh

SPDIF_record.sh

Playback_to_Headset.sh

I found at Maplins.co.uk an optical to coaxial SPDIF converter (A17NY), you will also need a TOSLINK optical and digital phono cables {75 Ohm Coaxial cable) to make the connection to the Cirrus Logic. Element14 are cheaper for the cables.

In Audacity you can adjust the playback volume with the slider. To adjust the record volume you will need to copy the script and edit the line. For example for copy the Record_from_DMIC.sh to a new file Record_from_DMIC_High.sh and change the lines from 116 to 150 – see below after the edit.

amixer $1 -Dhw:sndrpiwsp cset name='IN2L Digital Volume' 150

amixer $1 -Dhw:sndrpiwsp cset name='IN2R Digital Volume' 150

Save and run the new script. Now the recorded sound will be louder.

In LXMusic the volume level must also be adjusted by changing the Playback_to_Headset.sh. Copy this and rename the file for low or higher volume. For example for quieter sound change the line from 116 to 85

amixer $1 -Dhw:sndrpiwsp cset name='HPOUT1 Digital Volume' 85

It would be good to implement a digital volume control via the GPIO of the Raspberry pi, but that is for another day. Enjoy your Cirrus Logic card it sounds so nice.
