I have a new installation of volumio 1.55 on a Pi 2 with a HiFiBerry Digi+. Music plays as expected, but my DAC shows that its input sampling rate is 32kHz. I’ve set the audio output format under playback->resampling to 16 bit 44.1 kHz, and this is correctly reflected in /etc/mpd.conf.
I’m new to audio on Linux. How do I confirm how the output is configured? What else should I check?
sure that it is not reporting 32bit instead of kHz? I get my best results so far when I turn re-sampling and software volume control off. That disables any involvements of any software components fiddling with the signal.
