Did you run as administrator before installation?

Finally collected ud130 from the post office today.

I'm using Samsung Note 9, playing through UAPP connecting to ud130 with fiio CL06 cable. The app recognise the device and playback is running on the phone. I just couldn''t hear anything from the output.

LED flashed during boot up and off when UAPP continue playing. No indication whether it's low or hi gain as per the user guide.

Swap to the cable came with the device and connect it to the phone using the Samsung otg adaptor. Same result.

Tested it with hidizs ap60 pro too. Ud130 was detected by the player. Same behaviour as phone.

So for now I can't use it on the go with my phone or music player.

Did I do anything wrong or not doing something right to make it work with the phone? Or is Note 9 not supported? I am shocked if it isn't.

Went home test it using jriver and it's working fine. Low gain have to turn all the way to 2 o clock  to reach my usual listening loudness. Hi gain make the sound bigger at 1 o clock settling.

Sound musical and nice in the brief testing .

The device look solid and light for portable use. Slightly thicker than I have imagined but overall still happy with the physical size.

This is certainly odd. The UD130's Audio Receiver dates back to Windows 7 Era!

Can you try it with USB Class 1.0?

Hi raif,
Nice! Though it's working for u, there are just too many cables on the table that my wife will approve. 

What's the reason for not directly connect L27 to ud130? Is it because Sony do not have enough power to drive ud130?

That could be the reason why my player was detected but no sound from the DAC. Battery also drain noticeably faster when DAC is connected. Got to try the split cable one day.

That is a very impressive setup. We have a customer (Malaysian) in Singapore who runs both the UD125 and UD130 with a very clean separate power bank to his DAP/Phone setup as well
