Can you try to use USB-C OTG adapter and standard USB-A to USB-C cable? Because our UP4 doesn't seem to work properly with USB-C-to-USB-C cables.

There's a Windows 10 driver issue on UP4. The device "pauses" when there's no audio playing, and just turns on when needed. As a result, audio is muted for the first 1.5s and then fades in. So I can't hear the first 2 seconds of audio. This always happens in Youtube (all browsers) and Groove app for music. It doesn't happen when using other DACs.
There are no special drivers for UP4, it's using standard system drivers.
UP4 was designed to act this way.
I tried updating the firmware to 1.3 from 1.25 through the app and it keeps stating update failed, I noticed it on your website that older versions of the UP4 won't update through the app, I guess I have an older one...so I tried running the firmware update through windows connected to a usb C to usb A cable, pressed the power and mode buttons but the device won't go into DFU mode. Any suggestions?

Some models need 100% battery before going into DFU. Try charging completely and repeat the process. Mine went to DFU only after some 5 or 6 tries.
Tried it many different ways with the battery fully charged, almost fully discharged.
Red led comes on when is plugged in blinks once when i hold the power and mode buttons. It looks like it restarts because it causes my pc to hang for half a second while refreshing in device manager.
But no dfu mode.
Hello, im still w8ing for CarMode - Automatic On/Off on BT connection.
Any news about this update?

Nevermind, it wasn't fully charged. It was showing as 100% in the Android bluetooth settings menu on my phone but on the Shanling app it was showing only 40%.
Went into DFU mode after I let it charge for a bit and was able to upgrade. Hope the volume memory actually works now.
Thanks for the insight.
its bad, im going to buy second one DAC BT, and i have to take BTR5 quiet a bit more expensive from UP4. Or BTR3K but with out Sabre.. its bad. I hope to just take second one UP4

After the update, the Shanling Control app started working like a charm for me. What was once a useless app became a good control tool. What are your experiences so far?
And what about the suggestions I made earlier to @Shanling regarding digital and analogue volume controls in the app, and equalization (more frequency bars for the graphic equalizer - like in the Shanling Music app, maybe a parametric one, the addition of editable equalization memories for different headphones)? Is the developing team in charge of the app addressing these very important additions?
Same for me, it was useless before the firmware update. My only issue is that the battery indicator is not accurate, half the time it doesn't feel like showing me the charge % if its even correct. And for some reason the dual dac mode option disappeared after the firmware update. But at least we're moving in the right direction.
I own both the BTR5 and the Shanling UP4. I have a custom audio system in my car and all music comes from my phone, I use the BTR5 because the car mode feature is a necessity and makes it very convenient for me. If Shanling added this feature they could be alot more competitive because in this market segment there are only a small handful of options with Fiio being the most reliable choice.
The BTR5 is Shanling's main competitor, everything is comparable in terms of sound, different signature but I wouldn't say one is better than the other, they're different, sometimes you want chocolate, sometimes you want vanilla. In terms of features though and app working properly, I would say Shanling needs to step up their game.
I prefer using the Shanling though, I love the volume wheel and the shape makes it easier to velcro it to the cup of any headphones. Have it connected in balanced, sounds great.
Bit late to the party, but just ordered an UP2 so my Hiby W3 doesnt feel lonely.
@Shanling Can you tell us what features are being worked on for the next firmware?
And also is it even technically possible(would the hardware allow it) to have an option to disable charging and bypass battery during USB mode? Pretty good thing to have for maximizing battery longevity, so it would be nice to know is there a chance of getting that in some future firmware, even if not in the next one.
