piCore7.00 beta4  - here hifiberry DAC+ is found. But still it produce a similar error in dmesg (so this error is probably not important):

so in piCore version7 the Hifiberry DAC is found but in version8 it is not found.
In both tests alsa.tcz is installed via tce command.

Rich:
Hi sbp
From the version that works:

--- Quote ---
--- Code: ---[   15.596562] snd-rpi-hifiberry-dacplus sound: pcm512x-hifi <-> 20203000.i2s mapping ok
--- End code ---

--- End quote ---
Is it possible  i2s  got disabled in the newer versions?

Hi Steen

I don't have such board so can't test. Kernel config related to sound in 8.0 is the same as Raspbian. If it Works there look for differences in config.txt

Next week will be beta5 with 4.4.17 kernel but expect no deifference.

Bela,

I don't have the boards to test either, and not sure yet if it will fix the problem.   But the alsa-modules-KERNEL extensions are missing the module.
