Just as a reminder: the track position and total track length is not displayed correctly, at least not on a .wav file.
I play a 3-hour long concert (an excellent, uncut, raw concert .wav file) which does not display properly in the Playback screen.
After an hour, display does not change from 59:99 to 1:00:00 but back to 1:00. This happens for the next hours too.
Total time is displayed as 183:49, expected something like 3:03:49
Not sure if this is mpd or volumio UI
