HATs and other add-ons • Hifi Berry DAC2 HD on Raspi4 with Luks encryption does not work

Hello,
I have a very strange behavior on the Raspi that I absolutely cannot explain.

I have Raspi 4 running with RaspiOS 64bit lite edition, based on debian 12, without desktop. The kernel is 6.6.62+rpt-rpi-v8.
I have an encrypted root partition with Luks type 2 (xchacha20,aes-adiantum-plain64). The Raspi4 does not recognize the Hifi Berry DAC2 HD Hat. If I install the same OS, with the same configuration, without the Luks encryption, all components work very well. (I compared all installed files!) It seems that the Luks container of the root partition does not work with the hifi berry...

I have tried both Debian 32bit and Debian 64bit. In all cases the Hifi Berry did not like the encryption. The question is why.

What can I do? How can I get closer to the problem. I also set dtdebug=1 and compared the outputs, there are no anomalies from my point of view.

An interesting fact: Raspi5 has no problems with encryption and hifi berry (kernel: 6.6.62+rpt-rpi-2712)

I think, I need some support
thanks.
