I, too, have recently received my brand new Snowsky Echo Mini (purchased on AliExpress), and have been super happy with the sound quality and nostalgic build.
I am having problems, however, with the device not recognizing my music's metadata/tags.
I have a 200GB SanDisk micro SD card inserted in the Echo Mini, with about 150 gigabytes of music albums - all mostly 24-bit/192 kHz and 24-bit/96 kHz, and some 16-bit/48 kHz.
I have very carefully tagged all these albums using the macOS Music Tag Editor 2 application (so all have proper tags for album name, release date, album artist, track artist(s), track numbers and album covers). The albums are organized on the micro SD card in the following folder/file structure:
[Micro SD card root directory]
\Music
...........\Flac 24 (for 24-bit Flac music albums)
........................\[Album artist name]
.........................................................\[Album name]
.................................................................................01.Track name.flac
.................................................................................02.Track name.flac
.................................................................................03.Track name.flac
.................................................................................etc.
...........\Flac (for 16-bit Flac music albums)
...................\[Album artist name]
....................................................\[Album name]
............................................................................01.Track name.flac
............................................................................02.Track name.flac
............................................................................03.Track name.flac
............................................................................etc.
When I insert the micro SD card with my tagged music arranged as noted above into another audio player (a Sony hi-res audio Walkman), it recognizes all the tags properly and allows me to navigate my music using these tags.
On the Snowsky Echo Mini, however, when I perform a media library update on the micro SD card, the process completes fairly quickly (taking probably around 30 seconds, maybe even less), and when I try and access my music through the player's "Playlist" interface, I can only see all songs (from all albums) listed with their file names under the "All songs" category, but any attempt to access my music via the "Album", "Artist" or "Genre" categories results in there being only a single "Unknown" entry listed there - meaning none of the tags embedded in the Flac music files are being recognized by the Echo Mini, making folder-based navigation the only (cumbersome) way to access my music.
One more problem - when I do access my music via folder navigation, sometimes when I select a certain track, the player will play back a later track in the same album instead (for instance, I select track 7 in a 12-track album, but the player starts playing back track 10 in the same album instead). If I then skip back to the track I actually wanted, it plays back absolutely fine. Very strange!
I have updated the player to the latest 1.46 firmware version, and the problems have not gone away.
Anybody here experiencing the same? Any ideas on what I may be doing/tagging wrong, and on how to get the player to properly recognize and allow navigation by the metadata I've embedded in my Flac music files?
Would be amazing if Fiio could weigh in here, too.
Thanks!
