How can I be sure Volumio isn't downsampling

Help and Support Help

Is there a way to know what sampling rate and word size is being sent to the audio device? I’d like to be reassured that Volumio isn’t down-sampling my hi-res audio files by mistake or mis-configuration.

I’ve got a HifiBerry on order - can’t wait to hear it. I want to be sure the full 24 192 signal is being sent to it when playing such a piece of music.

Thanks!

  1. Look at the mpd.conf. If there is not an entry like this:
format                 "44100:16:2"

mpd won’t resample.

  1. While playing music, you can check this:
cat /proc/asound/card0/pcm0p/sub0/hw_params

May be, your “card-no” is another one.
