Cirrus logic audio card

Help and Support Raspberry Pi

Hi,
I have cirrus logic audio card on my rpi and it worked. today I updated the system and it stopped working. the error in the dmesg is:
arizona spi0.1: Failed to request DCVDD: -517

it seems that there is no arizona-ldo1 module compiled in the latest kernel while in previous kernel this module was compiled.

It seems you are correct.

osmc@osmc-pi3:~$ find /lib/modules -name arizona-ldo1.ko
/lib/modules/4.9.29-15-osmc/kernel/drivers/regulator/arizona-ldo1.ko
osmc@osmc-pi3:~$

Perhaps @sam_nazarko can explain why it’s not in the new kernel.

4.9.y is not the latest Pi kernel. It should be 4.14.

7

The issue is that the new kernel does not provide this module

8

I think you want CONFIG_REGULATOR_ARIZONA_LDO1 set.

9

Is it possible to reenable this module in osmc ? Cirrus card driver that is available in osmc is not usable without this module.

Hi

Hopefully the issue is now addressed with the following commit:

I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:

  1. Login via the command line
  2. Edit the file /etc/apt/sources.list
  3. Add the following line: deb http://apt.osmc.tv stretch-devel main
  4. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  5. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.
