Thanks for your quick answer but it is not working as I would expected.
My music collection is organised as follows: Music folder -> subfolder per Artists -> Albums per artist (tracks from one album per folder). When I follow your instructions with 3.0.2 firmware only the tracks directly in top music folder are shown/played but not from subfolders. On 3.0.1 firmware only the first album folder of the first artist is played.
Does it mean I need to organise my music differently?
For now I stick by 3.0.1 firmware.
Regards,
Keram
