Clave: driver version? stupid question but I assume you had your DAC turned on and connected when installing drivers right? I have no issue with version 2.19.0

I've tried all drivers previously posted in this thread, including the modded WaveIo ones, same result.

You don't need the XMOS interface connected while installing, in fact usually you first install the driver and after you connect the device.

My iRDAC XMOS drivers and all the others from Chinese vendors (Weilang, Leaf Audio) install fine.

It seems the OS thinks linked drivers have been tampered and refuses to install.

It may be a problem with the installation of unsigned drivers Windows.
It describes how to install unsigned drivers. But this is Russian language...

it didn't allowed me to install drivers unless HW has been detected with original ustar drivers so either your drivers are OEM without HW protection or ustar drivers are specifically made for ustar HW, nevertheless ustar drivers works with ustar HW under win10

Absolutely. I did make it work this way:

Execute from an elevated prompt:

bcdedit -set TESTSIGNING ON
bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS


Restart PC, install driver, test it.

Then from an elevated prompt:

bcdedit -set TESTSIGNING OFF

Restart.

It will work but sincerely I don't like to have an unlicensed and/or tampered driver so I'm trying to return the board, I've already have an Amanero (LKS version) which works great and doesn't have such problems.
 
link download driver for Ustar usb http://pan.baidu.com/s/1c20n7yS

Thanks but it doesn't seem to work.

I'm not able to undestand the error though:

I have 2.23 if you need it. It is from ustars audio.
I have blue xmos board.
I have not tried it on win 10.
I have linux based player and no problems.
Any recomendation how to get direct DSDfrom linux to xmos... now i have MPD as controler in Open wrt but version 15.05.1 is not direct DSD compatible just Dop.
Thank you.
 
Next question , what are the current demands for the 5v ,10v and 15v supplies on the dual 4495 board?
Does the volume control header need to be populated or jumpered ?
Has anyone managed to get remote control functionality working with the AK4137 board?

Hi guys , have my AK4137 AND DUAL 4495 board up and running but volume is very low and is louder on the right chn than left.
The only way I get sound is with jumpers 10 and 11 closed.
Jumpers 8 and 9 from the old pin config diagram, for running in dual chn mode are not present on the new dual 4495 board.
Help!
 
Hi Gordon,

sorry for late reply, not enough time :) , if you plan to use all those onboard regs than these would be my recommended values with some spare current counted in

5V - 100mA
10V - 200mA
15V - +/- 100mA

Use those blue trimmers on position (VR01 and VR02) to adjust output level per each channel...

regarding jumpers, those originally provided where taken from single board so your current pin 10 and 11 should correct to use

Regards

Daniel

Hi Daniel , tried adjusting the pots but it made no difference to the volume ,but it did increase or decrease dc offset.
Finally got it working by removing 10 and 11 and jumpering 2,3and 4 . I guess it is working in offline mode but at least it is making music now.
I had a further look at using a remote but if you follow the traces from the sensor position there are 3 pairs of smd pads for resistors or capacitors which are not filled so I don't think remote control will work with the AK4137 board. Can you ask the designer if this is the case.
Otherwise the sound is pretty good on my test rig even though I am just using Phillips NE5534's on the output until my SS audio opamps arrive.
Thanks for all the help.
Gordon
