I just bought a usb C to C and it didn't read my up4. It didn't even wake (charge) the up4. Tried the cable phone to phone, connection worked fine, charge and transfer data.
Any suggestion which cable c to c that worked fine as direct usb dac for my phone?
UP4 do not work properly with USB-C to USB-C cables. We recommend to use standard cables and USB-C OTG adapter if needed.

Should be fixed in latest firmware right?
Firmware V1.3.0 is latest firmware. For this issue with volume, I don't think we managed to replicate it with our units.

Hello. I have owned an UP4, paired with Samsung S10.

Is it normal that:
- using as USB DAC is it much quieter than my Hidizs S3 in all configurations - low gain, high gain, dual dac, 3,5 mm, 2,5 mm (and max volume is even for 2,5 and 3,5);
- using with 2,5 mm balanced headphones dual dac option is not available (in BT and USB mode);
- using as BT DAC with LDAC codec is a WAY LOUDER that Hidizis;
- using as USB DAC only volume control and mode button are working (clicking on wheel button does nothing);
- using as USB DAC Shanling Controller did not recognize UP4.

I am using Final Audio E5000 with 93dB/mW and 14 Ω.

When using 2.5mm balanced, both DAC are working at default. As it's balanced output.

Shanling controller works with UP4 only over Bluetooth, there is no support for settings over USB DAC.

When using as USB DAC, the playback controls do not work, they are only for Bluetooth playback.

If you are getting lower volume when using as USB DAC, I can only recommend to check settings of your software players. As some of them adjust the overall volume (UAPP being one example).

Thank you for your reply @Shanling

Are there any plans to add support for these options in future firmware updates? Is it possible?

What about increasing USB output quality? Are there any plans to do this? Is it doable? 16/48 is very limited. I know that this device has USB dac option only as addition to main functionality..

If you are getting lower volume when using as USB DAC, I can only recommend to check settings of your software players. As some of them adjust the overall volume (UAPP being one example).

You are right, I was checking it using application which not supports bypassing Android Mixer. Right now I am listening on Hiby Music and volume on USB dac is way louder. Thanks.

There are no plans to adjust the USB input on UP4. The 16/48 limit is due to hardware solution, can;'t be just updated with firmware.

@Shanling do you have any updates about the option to disable charging and bypass battery during USB mode?

No need for any promises or dates. Getting to know if the team would at least consider to add this option on a future update would be enough :)

(last update was Post #1,081 of 1,280 )
It seems it's not possible on the UP4, due to the way its charging circuit is designed.
it's available on UP5.

It's our recommendation to use charger that can provide standard 5V/1A output.
We had some reports of PD chargers not working properly with UP4.
I came here to ask about this.. Just realized that I'm not getting any feedback while charging through USB PD, but the light turned on if I used a A-to-C usb cable (same charger though, with the same 3A at 5V capacity)

Glad that it's not just my unit

is there any way i can activate both DAC when i use USB cable on 3.5 output? the quiet background is no brainer for its size, i've never heard any like that since Piccolo DAC

*on the side note, i recommend you put better shielding on UP5, imo the added noise on BT connection caused by interference from BT module

Dual DAC mode works in USB DAC mode same way as any other time.

Does the warranty cover the detachment of the caps from the case, possibly due to a swollen battery?

It hase less then 2 years so not to long.
Yeah, I would definitely recommend to contact your seller for warranty on this.

Having settled on the Shanling UP4, I'm now in the market for a BT receiver/transmitter to pair with. I'll be connecting to a Sony TV and a couple of consoles, so watching shows and gaming (APTX LL is a must) then the BT receiver will connect to the Shanling UP4. The device needs to be able to transmit a BT signal.
I did find the Shanling BA1 and seems like a good pairing.
Any thoughts or suggestions would be appreciated.

BA1 is only receiver, no transmit capability.
Most codec rich solution available for the purpose would be Fiio BTA30 transceiver, besides SBC/AAC/aptx/aptx HD/aptx LL youll also get LDAC(when using optical or coax input, over usb max is aptx HD), and im not aware of any other transmitter supporting LDAC.

Another solution for aptx LL is getting a not that expensive mini pc, and adding linux to it, aptx LL support was added few weeks ago via pipewire and you can use whatever bt dongle you have with it. So for around the price of the BTA30, you can get a transmitter with support for all relevant codecs, a receiver with support of up to aptx HD, AND a Media Centre PC aka HTPC as a bonus :).

But since to use it as a transmitter you would need to use the pcs soundcard input, im not sure how much delay would that add,
since i havent compared with BTA30. Might be better, might be worse. So if you feel up to the task and/or already have available pc you can check if it fits you. You can even use your main pc and boot with Live USB for testing, without actually installing linux.
I know Fedora already comes with pipewire out of the box, and in ones that its not installed ootb you would need to replace pulseaudio with pipewire.
