Hi, I have done a comprehensive test on x5iii (USB DAC mode)

I want to post some bugs that I find while using my x5iii (Firmware version 1.20)
*Fiio music player version 3.4.1

(1) Android device connected to x5iii directly

Settings:

Equipment:
Xiaomi Redmi5 (late 2017 model) - 3GB/32GB storage.
Fiio x5iii.
Philips Fidelio X2 headphone(32ohm)
Sony MDR-1aDAC headphone(40ohm)*DAC off, Power off, 3.5mm headphone jack only.
UGREEN OTG adapter(model: 30453)

Android device(Xiaomi Redmi5):
*enable Developer option in Settings.
*Developer option TURN ON ==> USB Config. ==> [Audio Source].

x5iii:
*USB DAC mode.
*Pure Audio mode ENABLE.

Music Player(on Android device):
MOOV music streaming service app
ONKYO HF Player app(paid version with DSD playback enabled)
Google Play Music app


*************************************


[TEST 1] Connection:
Xiaomi Redmi5 ==> UGREEN OTG adapter => Fiio x5iii USB cable ==> Fiio X5iii DAP


Bugs found:
The screen display shows wrong music format information.
*for example,
When everything is connected and first turned on, it displays 192kHz - 24bits, due to the DSD file that I played from local play prior to this test.

No matter which songs I play (from  any of the above mentioned apps),
The display (in USB DAC mode) still shows 192kHz - 24bits.

See attached images,
Diana Kralls (SACD) - songs are 24bits/96kHz FLAC after DSF to FLAC conversion by dBpowerAmp software.


*I have tested with iPhone 8+ and the display shows correct music format information when switching songs.

Remark:
iPhone 8+ can use Fiio x5iii as USB DAC by using Fiio K5 dock/headphone amplifier with "Apple Lightning to Camera adapter".  
iPhone 8+ cannot connect to Fiio x5iii directly even with "Apple Lightning to Camera adapter" due to insufficient USB power.

*************************************

[TEST 2] Connection:
Xiaomi Redmi5 ==> UGREEN OTG adapter => Fiio K5 USB cable ==> Fiio K5  ==> (docked)Fiio X5iii DAP

Bugs found:
The screen display shows wrong music format information.
*for example,
When everything is connected and first turned on, it displays 192kHz - 24bits, due to the DSD file that I played from local play prior to this test.

No matter which songs I play (from  any of the above mentioned apps),
The display (in USB DAC mode) still shows 192kHz - 24bits.

Bugs found with Foobar2000 (Windows 10)

Hi, same bug,
wrong music format info on Fiio x5iii display while using Foobar2000.

I play a 24/96 FLAC file, but the display just does not update the music format info
(see image)

**REMARK: it has no problem when I use Jriver (latest  version 24) on Windows 10 PC.
