Volumio 3.703 + Pi 4 + HiFiBerry DAC2 HD

Gisteren zeker meer op dan alleen eten :rofl:

Valt mee :sweat_smile:

Hi @nerd , this morning I redid the tests, this time with the correct sound card :sweat_smile: and the results of sudo cat /sys/kernel/debug/clk/clk_summary are still identical for good and bad situations.
Still no go :frowning:
I also tried to eliminate any other factors like:

  • Replacing the NVME SSD with an old school SD card
  • Removing the DSP module
  • Disconnecting the RTC battery (which I initially thought solved it, as I had 3 “good” reboots after that)

Unfortunately none of these had any lasting effect.

Next I will try another Pi5 and a Pi4, unless you have any further tests I can perform on this setup?

p.s. This setup works flawlessly with both an IQaudIO Pi-DAC Pro and a Topping D50 III external USB DAC, so I doubt that it’s the Oi5 that’s the issue here…

Hey @quintino,

I don’t think there is much that can be done here without i2c backporting from kernel > 6.6 to kernel 6.1. Although the code change for i2c_device_id linux/drivers/clk/clk-hifiberry-dachd.c at fbd8b3facb36ce888b1cdcf5f45a78475a8208f2 · raspberrypi/linux · GitHub seems to be trivial on the surface, yet the change causes a domino effect. Unless guys from HiFiBerry have a trick up their sleeves, waiting for a future release with kernel 6.6 is the only viable option.

Kind Regards,

Hi @nerd ,
Thanks for all the effort you are putting into this research.
What a shame that (currently) HiFiBerry DACs won’t play nice, but it is what it is.
Please let me know if I can do any testing of the DAC2 HD in the future, I’m glad to help out smooth any kinks in Volumio. In the meantime I’ll add it to my collection of “maybe one day” hardware.

Hello again @nerd, sorry to say that I’m back with the same nonfunctional player after a routine reboot. Running 3.742 with your baud rate addition to userconfig. This may be the first time I’ve rebooted the system since I last posted on 8/7; I leave the system running almost all the time.

Log of nonfunctional player immediately after reboot: http://logs.volumio.org/volumio/yigzCo6.html

Log of functional player after I2S off → full reboot → I2S on → full reboot: http://logs.volumio.org/volumio/peDTY1P.html

Hey @eduardo,

Thank you for the logs.
There is no new entries for the HifiBerry device in kernel 6.1, not much we can do here.

Kind Regards,

Dear Volumionauts,

Promising results from HiFiBerry DAC2 HD initial testing.

Kind Regards,
