Hm, so far in testing .mp3 and .m4a files this issue is fixed as I said before in the new firmware. However, .flac file metadata and filenames are still ignored, and the album view sorts alphabetically. The .flac files I’m tesitng with do contain track number metadata and the filenames start with the track number.
TITLE=Mysterious Delirious Fluke of the Beyond
In the album view on the Clip Sport, that track would play last because of its position from the title places it thus.
I recommend SanDisk QA test with ogg vorbis and all other supported file formats to ensure track number information is processed correctly.
Please let us know if this can be corrected in firmware 1.18, and an estimate of when that’ll be available.
