My apologies for not reading all 85 pages, I just searched for "Playlist"....oh boy.
FYI, I own the DX50 for almost 2 years. The biggest pet peeves are the buggy implementation of playlist, gapless and replaygain - at least regarding playlist the new DX80 appears to be doing the same. I posted pretty much the same you will read below in the DX50 thread, got even an acknowledgement from iBasso Paul, but nothing has happened in the firmware to fix it.
Here it goes.....
Look at this perfectly good path:
/mnt/external_sd/Alvin Lee/Keep on Rockin'/05 - The Bluest Blues (feat. George Harrison).flac
/mnt/external_sd/Bruce Springsteen/Born in the U.S.A/06 - I'm on Fire.flac
/mnt/external_sd/Eric Clapton/Pilgrim/01 - My Father's Eyes.flac
Can the DX50 import this? No, it cannot. It just ignores that one due to the single tick.
I bet a fiver the DX80 will do the same.
Here is the funny part. If I select the song from the directory and add it to a new or existing playlist and export the playlist, the DX50 will create that very string you see up there. Can the DX50 import that playlist again? No, it cannot. Pathetic, isn't it?
So, if the DX80 owner would be so kind to try this - that would be greatly appreciated.
PLEASE!
To be honest, I was on the fence ordering the unit. I really like the design, the buttons and the two card slots - yeah.
RockBox for the DX50 solves all those issues. That just works. However, I don't expect a RockBox for the DX80.......
Cheers.
