Thanks for the prompt response.

Tested debugging and various apps. Swap cable too. USB debugging didn't affect the usb out in my case.

Almost gave up and decided to try USB1.0  and it works.

Music finally coming out of the headphone!!

Just got this yesterday. Played fine on Windows10... On another computer with Windows 7, no such luck. Complained about no driver. Does Stoner have any windows 7 driver? I already installed the Savi Audio software but no such luck

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.

Well at 1st I didn't then the 2nd time I did. Maybe I need to remove and install again.

Edit: After removing driver and installing it again, still no luck!! Anybody here has luck with windows7 and ud130?

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

Can you try it with USB Class 1.0?

I am using win 10 and it's recognised straight away. Have not been able to use it lately due to work.

One thing I realised though...hard to find short micro to micro usb that guarantee work with ud130.

End up getting a otg adaptor and use the cable that comes with ud130. And not all phones work with the DAC. But this is the fault of Android then ud130.

So if u happen to find a really short and cheap micro to micro cable that work with ud130 and mobile phone, grateful if you could drop the link here.

New UD130 user here. Thank to Stoner Acoustics for quick response.

Stingy person who using very old DAC and AMP setup before changing to this.

That's great. Thanks for the support.

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.

Hi, above is my setup to play Sony music player that has wmport.

A) Fiio L27 wmport to micro usb cable
B) Female to female micro usb cable
C) Micro C female to male micro usb adapter
D) Micro C male otg to type A female with power (female micro usb)
E) Micro usb male to Type A male cable (this cable is to power)
F) Cable that comes with ud130 (actually same type as E)

If anyone is wondering, the device underneath the sony player is another amp/dac which you can just ignore. Just sharing in case anyone wants to use ud130 with a Sony with wmport interface.
