Ok, possibly found the issue here:
Spotify and Spotify connect are not resampled in volumio as they not use mpd.
I’m writing a plugin that solves it, but it is not finished yet, and may not work after a reboot with i2s DAC.
But it should be fine soon… github.com/balbuze/volumio-plug … ace/volgrp

If that is still the case Spotify will never play on my DAC as I need to resample the bit depth to 24 bit and the filters I prefer are triggered by 44,1 .
Is there a way to reroute Spotify through MPD?
