  I am using su  1.3. 3 and now having problems with my sd card.  I have no files on the player and the card (Kingston 64gb) has all flac files.  Now it seems that every time I switch on,  I get presented with a screen asking me to scan he sd card or browse files even though I have not changed any files between switching off an on.  The card is formatted fat32 and I suspect that it might be a card problem and have reformated as exfat but still get the the scan screen on power up.  I have also tried it with only one album on the card and it still gives me the screen. Once choosing scan the card,  it scans very quickly and plays with no problem. I'm just finding this screw on power up every time a bit annoying.  Does anyone have any ideas how I can remedy this? Thanks for you help. 

 
Have you tried deleting all the database files and/or doing a factory reset?

  i add it on 220  +
what gain do u use? have u noticed the lower gain of the national is warmer and the highest equal to the original sound coming from the HO? I noticed it like a year ago.

i use no gain on dx50 and national

Interestingly, I had some kind of glitch in my 1.3.3 software, a weird corruption, and suddenly nothing would play in order (and yes, I had Play Order>Order checked).  After trying to jar it loose by checking other settings and playing songs, and failing, I decided to reinstall firmware.  But I thought, why not try 1.5.0 and hear what that sounds like after using 1.3.3. for a few months.  So I installed 1.5.0 and boy did it sound flat (using my C5 amp from LO).  Tried 4-5 songs I'd been listening to just a few minutes ago, all sounded flat.  So I installed 1.3.3, set it up w/FLAC>irr On>312 and tried again.  Now it sounded brighter and more vibrant.  Fuller without being shrill or muffled.  And better soundstage.   
 
Now if he could just figure out how to get gapless to work with it.

gapless can`t work with SU @ flac-only mode because Mango supports gapless play only through ffmpeg codecs. It should work with "All" selected but not sure, since stock sound is also changed in SU.

1) Make sure that after SU install You delete update.img files and after that do factory reset.
2) Delete folders before/after adding new music that Mongo creates on SD and internal memory and then do Rescan Library not Scan SD card.

Thanks for that coil
yes, I've tried all those permutations and it is the same.  It is even the same when the card is freshly formatted in both exfat and fat32. It seems to be only this card, so not the end of the world.  I'll keep trying to solve it and will post if I get any success 
 
Al the best

Update -  I seem to have cracked it. Used the "erase disc"  function in a Samsung galaxy player 4.0. Reloaded the card and scanning now seems back to normal. 
 
Thanks again for your help.

Found heavenly bliss:
 
Ibasso DX50 > The National > SU 1.3.3, FLAC>irr OFF>auto CPU > Sennheiser momentum over the ear.

I`m also having "same" bliss (SU 1.3.3, FLAC>irr OFF>auto CPU) but without additional amp (DX50 @ mid gain) and with Fidelio X1

I will have to try this. I'm getting odd stops in playback, like it will play half a dozen tracks and then just stop. Hit the button for the next track and it's all fine. Also, there have been a couple of very short pauses in random tracks.
 
Plus I found this:
 

 
The DX50 has been put in it's rubber case since I got it and I've dropped it a couple of times, but I didn't expect this! Thought the metal casing was tougher than that. Luckily it's on the back cover (can we buy replacement covers?)

 

[MCImes]

so I downloaded the file "dx50_sound_unlocked_1.3.3.7z"...how do I install it?

I have updated many firmwares before from 1.2.2, 1.2.8, 1.5...MSE, Rockbox, SE and maybe a couple others, so I understand how to do the update.

I downloaded dx50_sound_unlocked_1.3.3.7z, but then what? I tried loading it on to the DX and renamed it update.img, but the BIOS says invalid update or something similar. I tried giving it a .zip extention and unzipping it because it seems small (63mb vs ~160mb for other FW's) but winzip wont open it...

so this may be a dumb question, but what do I do with the file dx50_sound_unlocked_1.3.3.7z once its downloaded?

 

[olddude]

Double-click it and you will get a folder with the update inside of it. Open the folder and there is the Update.  Put the update in the DX50 and go to Advanced and then do the rest.

Odd stop? I didn't get it, but last night after loading in some new songs into my SD card, i realised the song then to lag whenever I am playing the songs. 
 
The knock and bruises on your player look painful, I rmb my 1st DX50 got a slight chip when I accidentally drop it on the floor

Guys, I really recommend to buy thicker silicone like I have from Mini Audio: http://www.ebay.co.uk/itm/Silicone-Case-for-iBasso-DX50-DX90-HiFi-Music-Player-/171330372118?pt=UK_MP3_Players_Accessories_Cases_Covers_Skins&var=&hash=item27e4160216
 
The quality is also better and I really like that those 3 buttons are on level with main silicone surface not raised like with original.

It`s probably tagging/metadata problem. I had same problem with one FLAC album and no matter what FW being used. Everything seemed ok with tags but there was one wrong line in metadata and I had to re-rip that CD. Thanks a lot to medmitry for helping me out with that issue! Don`t know what caused it but I think it was different software for ripping. Now I use EAC only and also line command to add art into flac file. Here is PM from medmitry explaining whats wrong (I hope he doesn`t mind):

Mango FLAC decoder fails because of cannot retrieve channel/rate information from the file.
Seem like this file has broken FLAC header.
 
If we go to http://xiph.org/flac/format.html we'll see that first METADATA_BLOCK must be with type STREAMINFO

STREAM
<32>	"fLaC", the FLAC stream marker in ASCII, meaning byte 0 of the stream is 0x66, followed by 0x4C 0x61 0x43
METADATA_BLOCK	This is the mandatory STREAMINFO metadata block that has the basic properties of the stream
METADATA_BLOCK*	Zero or more metadata blocks

STREAMINFO is the second one. The first one is PICTURE. It does not match the specification.
 
 
Anyway, I recode(decode/encode) this file using official tools:
 

flac -d ~/Downloads/09\ -\ Elderly\ Pair\ Beaten\ With\ Hammer.flac 
flac -e -f ~/Downloads/09\ -\ Elderly\ Pair\ Beaten\ With\ Hammer.wav

and have the new file which works fine in Mango player because of the first metadata block is STREAMINFO:
metaflac --list ~/Downloads/09\ -\ Elderly\ Pair\ Beaten\ With\ Hammer.flac
 

METADATA block #0
  type: 0 (STREAMINFO)
...

 
 
Conclusion, I'm sure most of PC players have workarounds for this situation(a header does not the specification a little bit) but seems like iBasso guys are not obliged to add this workaround to the Mango player.
Right now you can recode the album using some good tool which respects the specification.

I have red one so much better in terms of thickness and it feels better by far

Can You post a pic of red one? I have black but would like to see how red looks in real world. I have seen only green one on pic.
