I’m looking for a way to retrieve&display the current bitrate/resolution in use by volumio/mpd while playing…
Any suggestions??
Not 100% sure (not able to verify right now) but if I call correctly you have to look into /proc/asound/card0/pcm0p/sub0/hw_param something. There you can find the actual bitrate while playing.
