RPi Linux driver for Wolfson / Cirrus Logic Audio Card RPi Linux driver for Wolfson / Cirrus Logic Audio Card Jump toI've been working on a reworked driver, based on Linux kernel 4.9,that doesn't require out-of-tree patches to the upstream kernel modules.This driver also adds a lot of new features and bugfixes like fixedmicbias setting on LineIn, exposing of WM8804 status and AES bitsas ALSA controls and configurable minimum/maximum samplerate limits. InstallationThe driver is included in official RPi and Raspbian kernels since early 2017.Make sure your system is up to date and you are running RPi kernel 4.9.12 or newer.Source code is available from the usual place.Please note: If you've been compiling from source please switch to theofficial RPi kernel source. I'm no longer maintaining the code in my developmenttreeConfiguration for kernel 4.9 and newer Enable the driverAdd the following line to /boot/config.txt to enablethe Cirrus Logic card driver dtoverlay=rpi-cirrus-wm5102Note: MMAP support is already enabled by default in kernel 4.9, you nolonger need to add the i2s-mmap overlay. Setup module dependenciesThe cirrus driver requires some manually defined module dependencies,if you fail to add them the driver won't load properly.Create a file /etc/modprobe.d/cirrus.conf with thefollowing content: softdep arizona-spi pre: arizona-ldo1 Download and install 'usecase' mixer scriptsDownloadand extract it for example in /home/pi/bin.wget bincd bintar zxf./cirrus-ng-scripts.tgzNote: If you had installed the older usecase scripts for kernel 4.4 you needto remove them.You have to start the appropriate scripts before you can usethe card. For example:./Resetpaths.sh./PlaybacktoLineout.sh./PlaybacktoSPDIF.sh./RecordfromLinein.sh Additional configuration steps Disable RPi on-board audio device snd-bcm2835On Raspbian the RPi on-board audio device snd-bcm2835 isenabled by default. When you run aplay -l you'll seetwo cards, the Cirrus card sndrpiwsp and the on-boardcard bcm2835.If you don't need on-board audio you can disable it by removing(or commenting out) the dtparam=audio=on line from /boot/config.txt. #dtparam=audio=onOptionally: use fixed card numberIf you don't want to disable snd-bcm2835 or if you also havean USB audio device connected you might notice thatthe card numbers under which the drivers register will change.Sometimes the Cirrus card will card 0, sometimes on-board audio.The card number depends on which driver is registered first, whichis purely random.You can manually assign fixed card (slot/index) numbers usingthe slot option of the snd module.
Forexample, if you want the Cirrus card always to be the first andon-board audio the second one, add the following line to your/etc/modprobe.d/cirrus.conf file:For kernel 4.9 add this line: options snd slots=snd-soc-rpi-cirrus,snd-bcm2835 TroubleshootingIf something doesn't work as expected please post your questions inon the element14 site.In order to track down problems follow the steps below andinclude the URLs to the paste files in your post:.Add the following line to /boot/config.txt toenable devicetree debugging, then reboot your RPi. Dtdebug=1.Upload your /boot/config.txt file, theGPU firmware version, GPU firmware and linux kernel logsand the outputs of lsmod and aplay -l.The easiest way to do this is by using the pastebinitcommand which is included in Raspbian. Enter the followingcommands and include the URLs that are output on theterminal in your post: pastebinit /boot/config.txtvcgencmd version pastebinitsudo vcdbg log msg 2&1 pastebinitdmesg pastebinitlsmod pastebinitaplay -l pastebinit.
