I have just gotten my pi and hooked a HifiBerry Dac+ to it. I installed Volumio and as a test, first ran audio through the headphones out on the pi. This worked well enough.
Then, I set the i2s audio checkbox to checked and selected the hifiBerry Dac+ as my output, plugged the speakers into the DAC but …no sound.
I checked some knowledgebase articles referring to setting the dtoverlay, but looking at boot/config.txt Volumio already adds that for you when you select what i2s you have. I did check dmesg and found this rather suspicious bit of text:
[ 224.556431] OF: Duplicate name in i2c@7e804000, renamed to “pcm5122@4d#1”
[ 224.563242] i2c i2c-1: Failed to register i2c client pcm5122 at 0x4d (-16)

[ 224.563273] OF: changeset notifier error @/soc/i2c@7e804000/pcm5122@4d
Did I do something wrong while assembling/configuring?
Thanks in advance
