New reworked driver for Wolfson/Cirrus Logic audio card

hiassoft

I've been working on a driver rework, mainly to get rid of the requirement to carry around a bunch of patches to upstream driver code, and also to fix some outstanding issues and introduce some new features.

 

Most issues have been ironed out so here's the first public release.

 

Edit: the driver has been included in official RPi kernels. Just run sudo rpi-update to install it.

You still have to install the mixer scripts and add the /etc/modprobe.d file. See my website for details

RPi Linux driver for Wolfson / Cirrus Logic Audio Card

 

Source: https://github.com/HiassofT/rpi-linux/tree/cirrus-ng-4.9.0

Precompiled kernel: http://www.horus.com/~hias/tmp/cirrus/cirrus-ng-linux-4.9.0.tgz

New mixer scripts: http://www.horus.com/~hias/tmp/cirrus/cirrus-ng-scripts.tgz

 

Important notes:

  • The new driver bases on the rather fresh kernel 4.9.0 which means there's some risk of (yet unknown) issues. Use it at your own risk and please run "rpi-update" to get the latest firmware before installing the new driver.
  • The soundcard name has been changed from "snd_rpi_wsp" to "RPi-Cirrus", also several ALSA controls have been removed and new ones were added. This means the old usecase scripts and any custom-made scripts will no longer work. Use the new mixer scripts instead of the old usecase/listen scripts.
  • The new driver supports setting (and receiving) of the S/PDIF channel status bits (aka AES bits). If you add an ALSA card configuration file this means applications like Kodi can do proper AC3/DTS passthrough. A sample card configuration file (plus the mixer scripts) can be found here: https://github.com/HiassofT/rpi-cirrus-config
  • I haven't fully updated the documentation on my website RPi Linux driver for Wolfson / Cirrus Logic Audio Card  yet, will do that during the next weeks/months. But except for the things noted above most stuff should still work as in previous driver versions.

 

Please report back if you tested the driver (either successfully or unsuccessfully), any feedback will help me!

 

so long,

  • I have on problem..., i have all made like tutorials said

    (raspberry 3, raspbian 4.14, lcd touchscreen (no hdmi connected so))

    sudo rpi-update is done (with firmware suppression before)

     

         ./Reset_paths.sh

     

    give me :

    amixer: Control hw0: open error: Invalid argument

    (many times the same line, repeated again and again)

     

     

         aplay -l

     

    give me :

    aplay: device list:277: control open (0): invalid argument

     

     

    I was setup before with 4.4, and during my C++ test, all worked perfectly, playing with sine waves.... and without knowing why, sound stopped... and the aplay -l command has stop working...

    So i try :

     

     

         wget http://www.horus.com/~hias/tmp/cirrus/cirrus-ng-linux-4.9.4.tgz

         mkdir bin

         cd bin

         sudo tar zxf ../cirrus-ng-linux-4.9.4.tgz -C /

     

    nothing change...

     

    with :

     

         sudo nano /boot/config.txt

         dtdebug=1

         dmesg

     

    i learn :

    [    3.913997] snd-rpi-cirrus soc:sound: ASoC: CODEC DAI wm5102-aif1 not registered

    [    3.924215] snd-rpi-cirrus soc:sound: ASoC: CODEC DAI wm5102-aif1 not registered

    etc...

     

     

    But all that didn't help me, so... please help !! I spend all the day and the night on this, and i still can't find why nor a solution ...

    Thankyou very much for any help !

    Please don't use the ancient 4.9 kernel, it's heavily outdated. The driver has been included in official RPi/Raspbian kernels for well over a year now.

     

    Please remove all custom configurations (like blacklisting the raspberrypi-kernel package in Raspbian etc), use a unmodified Raspbian installation and follow the configuration steps from here RPi Linux driver for Wolfson / Cirrus Logic Audio Card

     

    so long,

    I already have try these configuration steps, and i have just retry, but unfortunatly nothing change, always the same problem.

    I have removed the customs lines, and re-enabled the onbord card, just to see if it's detected : aplay -l still don't work... (aplay: device list:277: control open (0): invalid argument)

    Sorry, i'm only good under windows, but not under a linux environnement...

     

    Should i format and reinstall a new raspbian to make it work again ? :-(

    And for my knowledge, why my sound card just stop working, i have nothing asked, no started update, no open terminal, just working as remoteGDB from visual strudio. I have already should reinstall all because it has stopped working, one year ago. I did not asked for that.

    So i suppose that silent updates are done, is that right ?

    Double-check if your configuration is correct. If you still can't get it working please post the dmesg, vcdbg log etc info as described in the Troubleshooting section here RPi Linux driver for Wolfson / Cirrus Logic Audio Card

     

    so long,
