DAC+ pi4 dtoverlay=hifiberry-dacplus does not load

None

Pi 4, new installation

DAC+ board (with HW 2.6)

Following the guide here

https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/

Does not load correct dtoverlay=hifiberry-dacplus.

Interestingly dtoverlay-hifiberry-dac loads

With and aplay -l that gives:

card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]

Subdevices: 1/1

Subdevice #0: subdevice #0

However,

Unable to even play a test wav file.

Weid - I assumed that the correct dtoverlay should be the hifiberry-dacplus.

If I us the same DAC+ board with a Pi 3 and use volumio (as a test)

All is well. Therefore I do not think that the DAC+ is faulty.

I am going around in circles.

I've also tried with

force_eeprom_read=0
in config.txt

What on Earth am I doing wrong?

Summary:

Linux raspberrypi 5.4.51-v7l+ #1333 SMP Mon Aug 10 16:51:40 BST 2020 armv7l GNU/Linux


asound.conf

pcm.!default {
  type hw card 0
}
ctl.!default {
  type hw card 0
}

For MPD, just tried several ideas and last was:

audio_output {

type "alsa"

name "My ALSA Device"

device "hw:0,0" # optional

mixer_type "hardware" # optional

# mixer_device "default" # optional

mixer_control "Digital" # optional

# mixer_index "0" # optional

}

Update - still an issue:

Downloaded and wrote HifiberryOS to SD for a test (Pi4)

The OS loaded OK

Under diagnostics - the DAC shown was hifiberry-dac

aplay -l

In the web UI - volume set ok

Replaced DAC+ onto a Pi3 - As previous post

hifiberry-dacplus dtoverlay was OK and board is detected and everything works correctly.

I conclude (interim) that there is an issue here that is related to the latest Pi Linux OS

What's the fix here?

A week back - ordered another DAC+ Pro for a project for a friend - it's on its way.

Is this a mistaken purchase and should I look elsewhere for an alternative DAC product? Up until this point I have been really pleased with all Hifiberry purchases (many) and now this!

Fairly disappointed and have spent ages trying everything that I can think of. I'm missing something or ... the overlay file - is there an issue?

(BTW - not a HW issue with Pi as tested on two Pi4s with same results.)

Fed-up!

:-(

hifiberry-dacplus is the correct overlay. However, if HiFiBerryOS doesn't detect it there's a good chance that there is a hardware problem. Do you have anything connected to the GPIOs? Othertwise try another SD cards as defective SD cards can also result in all kinds of crazy behavior.

Yes - agreed, the hifiberry-dacplus should be the correct overlay. However - the Pi3 uses the correct overlay and detects the hifiberry-dacplus. - place the same DAC card onto the Pi4 and it does not work.

Sorry to be a pain but I have tested every possibility different SD cards, Raspberry Pi's 2 x 3 and 2 x 4. Using, as I said, the same Hifiberry card.

And it's not that I'm unqualified - I'm a computer scientist.

This is sub-optimal - why would the same downloaded image from the R Pi foundation result in the Pi3 behaving correctly but a write of the same image and run on Pi4 - does not?

Try to move the lines

force_eeprom_read=0
dtoverlay=hifiberry-dacplus

to the beginning of the file.
