Installing DAC on Berryboot

Hi everyone,

I've just installed Berryboot to manage several OS's on one SD card and I still haven't been able to figure out how to install my DAC+.

It seems Berryboot overrides the core modules of the OS when the Pi boots up. I have no idea how to have my DAC+ recognized by the system.

Does anyone have some experience with that? I haven't found anything on the forum.

Thank you!

  I managed to turn on the light on the boad after:
  

  
  
  1. Coping the /boot/overlays/hifiberry-dacplus-overlay.dtb file in Raspbian to a overlay folder at the root of the sd card.
     
  
  
  2. Replacing the bcm2709-rpi-2-b.dtb file at the root of the sd card by the one in /boot/ in Raspbian.
  
  
  3. Adding the dtparam=i2c_arm=on & dtoverlay=hifiberry-dacplus in the config.txt at the root of the SD card.
  
  
  

  
  
  So far, I have no sound coming out my speakers... Sill investigating.

  Ok the card seems insalled but I don't know how to set it as main device.
  
  

  **** Liste des Périphériques Matériels PLAYBACK ****
  carte 0: ALSA [bcm2835 ALSA], périphérique 0: bcm2835 ALSA [bcm2835 ALSA]
    Sous-périphériques: 8/8

    Sous-périphérique #1: subdevice #1

  Ok so, just have to do that:
  Create the /etc/asound.conf file with the following content:
  
  
  

  
  pcm.!default  {
       type hw card 1
      }
      ctl.!default {
       type hw card 1
      }

  
  
  
  
  
  That works.

  Hi,
  
  thanks for this info. Another option is to completely remove the driver for the onboard sound from the module configuration.
  
  Best regards

  hifiberry, can you explain how to remove the driver for the onboard sound from the module configuration?

  Hi,

  I don't know how to do it on Berryboot, but on a normal Raspbian installation, you just need to remove the onboard driver from config.txt:

  I just found the issue... it's as simple as the extension being changed from *.dtb to *.dtbo.

   

  [code] dtdebug: Failed to open overlay file 'overlays/hifiberry-dacplus-overlay.dtb'[/code]

   

  Obviously... the new overlay extension is now hifiberry-dacplus.dtbo.

   

  So... add 'dtoverlay=hifiberry-dacplus.dtbo' to the config.txt... all's good after that. No need to transfer files from Raspbian. :)
