I got a new raspberry pi 4 with a fresh buster installation. and a hifiberry DAC+ HW 1.0 

When I follow this Tutorial here 

and then put "aplay -l" I end up with this 

aplay: device_list:272: no soundcards found...

 

my /boot/config.txt (only the audio part) looks like this 

 

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
#dtparam=audio=on
dtoverlay=hifiberry-dacplus

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
#dtoverlay=vc4-fkms-v3d
dtdebug=1

When I run dmesg I find the following 

snd-rpi-hifiberry-dacplus soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered - will retry

Can anyone explain why the dac+ is not detected ?

  Try disabling the vc4-fkms-v3d driver. I think, we had some some problems with this in the past.

  Thansk for your reply. I disabled it in the config.txt but it still does not recognise any soundcard.

  Hard to say if there's a hardware or software problem. Try installing HiFiBerryOS (https://hifiberry.com/hifiberryos) and check what sound card is recognised.

  I installed hifiberry OS but how do I know what soundcard is detected ? When I check the boot/config.txt I find the following: 

   

  awk 'NF' /boot/config.txt | grep -v '#'
  kernel=zImage
  disable_overscan=1
  gpu_mem_256=100
  gpu_mem_512=100
  gpu_mem_1024=100
  dtparam=i2c=on
  dtparam=spi=on
  dtoverlay=hifiberry-dac

  But I think it should say dtoverlay=hifiberry-dacplus since the dac+ is the correct sound card. Since hifiberryos is not based on debian I do not know how to edit the config.txt :(

  What DAC+ are you using? Light, Standard, Pro?

  If HiFiBerryOS doesn't detect it, there's something wrong with your Pi, the DAC or the connection between both. It is plugged correctly onto the Pi? Are there any other things connected to the Pi?
