[emms-help] Can't get metadata info from music files other than mp3

[Julien Cubizolles]

I'm using:
--8<---------------cut here---------------start------------->8---
(emms-cache-set-from-mpd-all)
--8<---------------cut here---------------end--------------->8---

The mp3 files are correctly accessibles in emms-smart-browse under the
right artist/album branch, but for the off and flac files, they are
under misc/album/01. 01misc...

I'm using emms-20160207.420 from elpa. Please feel free to share your
configuration for emms if you don't experience this problem :-)

Julien.

Here are some entries from tag_cache for mp3 and flac and the
corresponding ones in the emms cache:
