I upgraded from LE11 to LE12 (stable version) and there was a problem with the Hifiberry DIGI+. I have tried probably all possible configurations but I conclude that the problem is somewhere else.
To get the card to work I have to first insert the card from LE11 and then LE12 and then it works. Unfortunately, after rebooting it no longer does. It looks like it's a bug in the LE12 version.
Do any of you have similar experiences?
Maybe some update could help something.
My main settings:
force_eeprom_read=0
dtoverlay=
dtoverlay=hifiberry-digi
dtparam=audio=off
