I just bought one zx300, I inserted a 400gb sansdisk ultra microsd card, it is seen by the player on device info but after scanning it says there are no songs. Also I can browse the card while connecting the dap to my smartphone via usb-c and see all folders and files. It has many flacs and some dsds. Any trick? Should I reformat with Sony dap and copy again or...?

Yep. Reformat within the zx300... I also add the tunes whilst still inside the dap too

Create a folder named "Music" and move all your music files under there. This will solve your problem.

I reformatted my disk on the player. But also you must create a root directory called "MUSIC" on the card The player only recognises music files in this directory and its subfolders (Why? it's Sony...

Put all your music into a folder called "MUSIC" at root level of the microSD; The Sony can read disks formatted as exFat.

Ok, thanks, I'll try.

as rightly advised by other members .. create folder named "music" and place all folder in it

works now, i only had to move all folders within 'music'
next i need to get a good 4.4mm ended cable because standard 3.5mm output is weak, using hifiman re2000 i only listen at max volume, clearly they are underused.

If you bought your DAP in Europe, or it came from an EU country, it's voltage limited. Flash firmware from a different region to unlock the potential.

Will do, it has 2.00 firmware version, latest is 2.02, I assume choosing region is a step of setup while installing or on first start after update.

No, it's done using the Rockbox tool, I believe. Sony cannot provide any tool for this. There are people on the forum who can help with instructions.

aha, rockbox, ok, i used it for some old daps liks sansa clip and ipod classic. i'll give it a try, hopefully i won't brick it and it is reversible, on ipod classic it wasn't, on sansa clip i was able to choose between original os and rockbox.
edit: i found the exe, it's for changing sound limitations, not to install a new os, thanks.

 

[LightBlue77]

i think there is no sound limit, i get this when checking with the exe from rockbox:

 

[LightBlue77]

aha...works! looks like it was like this by default or the previous owner removed the volume limit but without 'Reset all settings'. The volume is slightly enhanced, 100 level is enough now and i get beeps and warning when increasing it above 80 or so.
