Hiii Guys... Can the best person here want to share & make a complete video tutorial, how to full upgrade the old firmware or downgrade firmware shanling up2 via PC, especially in Windows 7 the case I'm currently experiencing (Because I only use a PC on my old OS Win 7)?

I experienced something similar / the same (before the launch of shanling up2 application) ... I had difficulty in upgrading the full firmware to v1.5 ... And the result I was still in the old firmware v1.2.5 (Default Sales) as in the case above the "CSR BlueCore in DFU mode" was not detected in the PC Device Manager menu ... I have tried replacing the original usb cable from the shanling up2 sales box or other alternative USB cables, can't read it. ...

Hi,
when you try to set your UP2 into DFU mode, how does it show up in device manager please?

I rewired the headphone plugs for Denon to the "TRN" balanced cable. Now I'm listening to hi-res from the Qobuz stream on Denon D600 on the balance output. In comparison with the unbalanced output - the sound seems more detailed, the amount of "meat" has reduced somewhat, but not critically - the bass is more collected.

I connect UP4 to my iPhone and I can control both iPhone volume and UP4 volume. Should I max out UP4 volume and control the volume only through the iPhone?

I would recommend to have some balance. Set your phone to like 50-70% and set volume on UP4 for ideal listening levels. And then use your iPhone's control, if it's the more convenient way for you.

It's alway ideal to have 50-50 on phone and up2/4

Appreciate the effort from Shanling but for my part I've never really cared about an app. I upgraded firmware easily and then installed the APK and looked around. Honestly there's nothing it does that can't be easily done via the device control just as easily. I don't really need/want an extra app just so I can look a GUI doing the same thing. Part of the reason I like the UP4 is it's simplicity. That said, it works completely fine, but I uninstalled it (the app).

I appreciate the app and believe it will expand it's functionality over time. It also makes it possible to force a certain codec into action by deselecting all the others. Although, I wasn't able to force AAC with the Xiaomi Mi 9, it always resorted to SBC. On the Huawei P smart 2019 OTOH, forcing AAC was possible.

A bug with the app thoug is the impossibility to close it. I always remains running.

@Shanling So any response about addressing the volume issue on the UP2 with V1.7.3?

I understand correctly that on Linux does the usb dac not work correctly? I tried to find out the cause of the problem, and here’s what I understood: if the initial sampling frequency of the music is 48kHz then the usb dac works. If the original sampling frequency of the music is 44.1kHz, then there is no sound. The system tries to play 44.1 natively, but there is silence in the headphones. Now I will try the 4.19 kernel. I am interested in the pattern.
By the way, everything works well on Windows. It's a pity we do not have 192/24, but this is the lesser of troubles
I've use Manjaro KDE and pulseaudio 13.0

BTW I use up2.
And a small question, is it possible to forcibly make 44/16 on LDAC on the android (I have root)? By default system set 96/32 in any case.

Unfortunately we have no linux machine, so can't really test it for now.

On Android, in developer options you can change the LDAC's setting to 16/44.

There are many linux users who buy your products. As you can install a linux system on pretty much any computer for free, it would kind of make sense from a business perspective to at least do some basic testing. As it stands, I haven't noticed any issues with linux and usb, but can check with my UP2

44.1 FLAC works ok for me. Using Audacious and ALSA as backend.

 

[MrNekit]

For me it doesn't work. I think troubles in ALSA, coz it doesnt work both with clean ALSA ouput and with pulseaudio to alsa. I've tried Audacious, no sound here in 44.1khz, in 48 all good .
But also I've tried deadbeef, there are much interesting: 44.1 playing in 48 without any resample. It's just faster and higher (higher tonality).
I've edited previous post and added some technical info.

Which distro? (debian? / fedora?)
