HATs and other add-ons • Hifiberry overlays shared over multiple DAC??

I had a problem with a pcm5102a hifiberry dac with my raspberry Pi 5 model...

I was using some various set of instructions and all were variations of
this config.txt append:

dtoverlay=hifiberry-dac,slave or ,noaudio or just dac. rpi-dac.
None worked.
The Pi 5 uses some new i2s protocol, or has a faster clock, or something else changes from Pi 4, that I haven't found
one person that could say he had it working on a Pi 5. None.

I thought maybe my model is unsupported... made some research for other dac...
came around this NVDAC model from pi52 with combined SSD and Audio DAC

https://wiki.52pi.com/index.php?title=EP-0218



And the instructions at the end of the wiki also share the same

dtoverlay=hifiberry-dac,slave... just dtoverlay=hifiberry-dacplus,slave....


To which the question... what is hifiberry exactly doing for all these manufacturers DAC to all work on all
various Pi models?? Who is maintaining the overlays??? Does these overlays get specific updated for the
kind of dac detected??? Why so many DAC shares basically the same instructions???

Also the new EP-0218 seems to have problems with the Pi 5...
In my case I also need Jack to be able to detect whatever DAC from the boot,
and so far only Usb class compliant Sound card has worked for me,
completely negating the advantages for using an Audio Hat, or just a Dac, to
have a nimbler, cheaper built...

This is my DAC.
Anyone with a working solution for the Pi 5 that doesn't involve any of those hifiberry overlays is welcome...
