Does anybody have the same issue with their BA?
Mine takes two minutes to boot up. For two minutes it says Initializing CMI.
Follow my guide in regards to cleaning your tags. ID tags 3.2 don't play nicely on Hisound players. Use 3.1 tags for mp3 files. If using FLAC just use the basic Flac(Flac) tag and nothing else as having multiple tags will greatly slow down the unit. If you have a huge amount of mp3 files even though the tags are clean it will take longer to load the unit. With 2,500 FLAC files on my 64 GB card it would take 30 to 35 secs to boot on each start up. When you add songs or delete songs I recommend you delete the system folder in the internal memory which will reindex all the files (this takes longer the first time but loads much faster on each restart).
I always use multi formats card reader which is very convenience for me. Never tried transferring files with card stayed in my Rocco BA though. I supposed, that should not be a problem either?
It don't matter. You can do either but it's faster to do so from a card reader. You also need to format the card to FAT32 over the exFAT.
