Hi konki,
konki wrotehardware volume control working with arcam rDac!!!
I will take a look at this for you, maybe it is easy to solve. I need the output of the following commands:
cat /proc/asound/cards
amixer controls -c 1
amixer scontents -c 1
Replace the 1 in the second and third command with the card number of the arcam rDac given by the first command. You should run the commands when the arcam rDac is active and music is playing.
