iBasso DX90 Bug Thread - Post Any Firmware Bugs/Issues Here

The scan when you change card is considerable faster (provided the card has previously ben fully scanned) as all it does is transfer the prescanned library from the card to internal storage rather than scanning thru the entire directory structure as a full scan does.

An other problem with scanning that can result in an aborted scan is if there is not enough free space both on the card and on internal memory to store the library. DX90 will just abort the scan and will give no message as to why the scan did not complete

I did not know it was faster in this case. Good to know - I may buy a second card :)

HI, I have just bought the DX90 and I'm having problems with the artwork. Everything runs smooth on iTunes, but many of the artworks just don't show on the DX90. My files are MP3 or ALAC.
 
Thanks for your inputs.

That is because a lot of iTunes artwork is not actually stored in the music files but rather in iTunes metadata

Will this work with .aiff files?


iCoverArt can embed album cover images in JPG, GIF, PNG, or BMP format into song files in MP3, AAC (and .M4P), AIFF, or Apple Lossless format (.M4A)

the 24/32 bit bug happens to me with .wav files, no with .flac

other thing, if you press pause on the screen, and while a song is paused slide the progress bar, the song will gi on with no sound, and you have to press twice the play button to recover normal functionality

For those who don't know, there are "old" Li-Ion cells rated at 3.7V avg/4.2V max, and "new" cells rated at 3.8V avg/4.35V max. Both Pisen and original Samsung batteries use new cells.
 
I've measured and found out that DX90 charges a battery up to 4.2V, while Samsung Galaxy S3 charges it up to 4.3V. It means, DX90 works with the battery like it has an old cell, and, as such, does not utilize its full capacity.
 
Here are results of measurements to show the difference for original Samsung battery:
 
If discharged from 4.35V to 3.2V, the capacity is 2060-2090mAh
If discharged from 4.20V to 3.2V, the capacity is 1785-1820mAh
 
iBasso, please rebuild the kernel for 3.8V batteries!
 
Edit: more experiments showed that the kernel level is OK, and it charges the Samsung battery up to 4.36V. But, under Mango player, when it reaches 100%, the charging process immediatelly stops and then the battery discharges, which is not as good as expected. E.g. when I put SGS3 on a charger, I take it off at 100%, regardless of how long it was connected to the charger, providing it has reached the 100% once. The experiment was done with the power from PC USB port and "Charge only" setting for USB, and "Never" for auto power turn off. The voltages were read from /sys/class/power_supply/battery/voltage* via adb.
 
Edit 2: From a wall charger, when DX90 is turned off, the charger application displayes "Charged" with full green circle when the battery has reached 4.2V. The charging process continues, but there is no a way to know when the battery is fully (4.36V for Samsung) charged.
 
If I disconnect the device from the charger at the level of 4.2V, and connect it back, there is a big chance of small discharge in between, and the charging process starts. It shows the green cycle shortly, but the charging process continues, with a chance for the full charge.
 
If I disconnect the device from the charger at the level greater than 4.2V, and connect it back with such a level, the green circle is shown immediatelly, and the charging process does not start at all.
 
So, I see the only way to reach the full capacity. It is to:
  1. Charge only turned off DX90, and
  2. Don't disconnect from the charger for at least XXX minutes after it says "Charged".
which is quite tricky!
 
The expected behaviour is that the charger application turns the green circle only when the battery has reached its 100% capacity, and then it keeps charging in small increments, to be almost 100% at any time.

also, when i scan my a-k card, the progress bar completes. with the l-z card it seems to go halfway and then go back to the main screen...weird?!

I had the same issue, and got it down to specific files. Where ever its stopping there is a problem with that file, if you work out where alphabetically its stopping, and remove that album/folder/track it'll carry on. Mine wasn't scanning far at all, removed the offending album (which was in the B's, hence it not getting far at all) and it carried on. Not sure still what the difference is, all the files on the card are AAC encoded in iTunes. Guess I'll just re-rip this one CD.

The problem is likely with the tags in the file. iTunes ripped files have lots of strange tags and the DX90 works best with only the most basic tags in the files (album, artist, track name, track number, genre and year).
