Understood - thanks for the prompt reply.

It's not something that can be adjusted by simple firmware update, this change needs to be done on deeper level in our factory.

@Shanling would you care to address my issue? Thank you, in advance.

Shanling, when you will fix 44.1khz by usb on linux devices? This is the same problem as with Linux on PC which I have reported some month ago (First report).

I have tried to use shanling up2 with my android device by usb (using UAPP) and there is no sound when I'm tried to play 44.1/16 files. If I play 48/16 file all working good. To reproduce this problem use UAPP or Hiby music in direct usb mode (without android mixer). Or download any linux distributive on PC and try to play 44.1 files without resample. And fix is please!

Hi, is this any workaround for this issue?
I'm using OnePlus 7 pro with USB Audio Player Pro and direct play via USB DAC.

No problem playing 48khz files, but when I play 44.1khz files, there are no sound.

Already updated to filmware 1.7.5 still facing this issue.

Thanks.

Just got UP2 and I'm unable to get the device recognised in the iOS app. However I'm able to get the device connected in the bluetooth menu.

Please try to update to latest firmware over computer, it's possible your UP2 has older firmware that's not compatible with the app.

Hello, I am trying to update to last firmware of UP2 on Windows. When I click "Start upgrade", there is "Bluetooth DFU" alert: "No DFU firmware in the current folder". The devise is in DFU mode, according to manual instructions. In "Firmware upgrade" folder there is DFU item. So, what is wrong?

Is your UP2 showing in device manager properly as DFU device?

 

[Gesualdo]

You mean item „CSR Blue Core in DFU mode”? Yes, it has appeared.

When I click on an application, it starts installing drivers. It says there:

"First: DFU USB Driver Installed
Second: Microsoft Visual C++ 2008 Redistributable not installed."

It seems, progress goes only to the half and then next window appear with „Start update” button.
Maybe issue is in this second task?

Didn't face such issue before. I would recommend to do fresh download of the update file, just to make sure you got all the files in correct place and without any error while unzipping it.

This is fine, no issue there.

I did the fresh download of the update file, but no effect.
I tryed on 2 computers with different Windows version. On one of the computer, in the past, I successfully upgraded UP2 to version 1.5 and there was no problem.
Can I download from somewhere version 1.6? Mayby from this version I could try to update version 1.7.5.
I would like to have acces to Shanling app, but from version 1.5 there is no possibility.

There is no version V1.6.

Here you can download V1.7.3, which is using same update method as V1.7.5 https://drive.google.com/file/d/1ygXJezKrQm7sgB1zN9ZJnwTOwVDtCIbr/view?usp=sharing

Just a suggestion: move the entire 'Firmware Upgrade" folder (and only that folder) out to the desktop, then re-run the process.
