Hi,

I am running Arch Linux with Raspberry4 kernel provided from Arch Repositories

5.10.27-3-ARCH #1 SMP PREEMPT  aarch64 GNU/Linux

it seems that the kernel compiled with the correct module but it not under

/lib/modules/5.10.27-3-ARCH/kernel/sound/soc/bcm/

zcat /proc/config.gz | grep -i bcm2708

I have the following under /boot/config.txt but the device is not listed under aplay -l

dtoverlay=hifiberry-digi

force_eeprom_read=0

If I need to compile the kernel again, where can I find the source for the digi+  ?

just to confirm under volumio the device is working, so no hardware issue here

 

Thanks in advanced

  This PI4 runs my music using the USB and I just added the hifiberry digi+

  Another linux distro is not an option. 

  Thanks

  The driver is part of the official Raspberry Pi kernel. As long as Arch Linux is using this, the driver is included. As we don't have any experience with Arch, we can't help further.

  HI,

  just to understand, this is your device/product, the only way to have your device working is to go to another company

  and search for solution or hifiberry and raspberry are the same company?

  Thanks

  I don't understand what your mean. You don't have to "go to another company". Our drivers are always part of the official Raspberry Pi kernel. We don't proide our own Linux kernel as this would be just a terrible idea.
  https://github.com/raspberrypi/linux
  
  However, we can't and won't provide support for exotic distributions like Arch.

  Thats fine , I agree you don't have to support all distro's BUT if you developed this board?, how can someone obtain the drivers/code of this board you developed? I have to use raspberry pi os to use your board?

  No, you don't have to. You can use all kinds of distributions. However, we can't say what is required for a specific distribution. You need to discus this with the developers of this distribution.
  
  The link to the sources is in the previous post.

  Hi,

  it seems to work with the RPI4 kernel when setting dtoverlay=hifiberry-digi

  but when I connect the audio cable I don't see the device in the aplay -l anymore

  the device is shown only when the audio cable is out.(after reboot)

  any idea why?

  Thanks

  well , its working fine now with Arch Kernel (rpi4)

  mpd.conf

                  device          "hw:sndrpihifiberry"

  Thanks
