I have several .wav files that are properly tagged with album names. Volumio sees the files, and can play them, but does not read the 'Album' tag. Because it cannot read the album tag, it does not group the content in the album view.
See attached screen grab....volumio groups 3 Radiohead albums (stored in .flac format), but does not see the album tag for the album 'A Moon Shaped Pool.' I have verified the album tags in both windows file explorer and mp3tag.
