[SOLVED] No thumbnails with v8.1.2

[Nutul]

Thank you all for the suggestions, even if I've already tried them and no luck so far...
...

For what is worth I do change a bit the default directory structure under /var/lib/mpd/music:

Code:

pi@moode:~ $ tree -l /var/lib/mpd/music
/var/lib/mpd/music
├── Beets -> /mnt/NAS/Mediatheque/Music/Beets
.
.
.
├── Classical -> /mnt/NAS/Mediatheque/Music/Classical
└── RADIO
   ├── 1.FM - Blues Radio.pls
   ├ ...
  .
  .
  .

...

Aha, so not a vanilla installation.
I don't have time right now to code-walk or try to repro but my spidey-sense is tingling over this bit of fancy footwork with the symlinks. Could be wrong, of course.
Regards,
Kent

Also... I see the album-art priority is set to "embedded"... I cannot remember the code right now (I believe if one search fails, it will proceed with the other, but am not so sure...) try to set it to "Cover file" in "m" => preferences...
Although it looks to me as if the hash-ed file name for the thumbnails is being calculated wrongly... (the big album-art is retrieved via a .php endpoint, and the codepath for it is different, AFAICR)
