I have a raspberry Pi with a Pi DAC Pro sound for which there is no
driver installed. Searching online takes me to readily prepared
operating system images that I do not want to use as I am using
Devuan. Does anyone know what I should do to be able to use the Pi DAC
Pro sound card under Devuan? VolumeIO, a strongly suggested OS, badly
smells of a software lock-in, something I really want to avoid as I
have already experienced it when I used Delphi under MS Windows.

Thanks.
