So the U16 drivers are version 4.47 of Thesycon drivers. That's the same version as FiiO's latest Q5/X7 drivers. So I copied the CplApp.exe, the Xml file and the ini file.
Rename them to GustardAudioUSBAudioCpl.exe, GustardAudioUSBAudioCpl.xml.
Insert the InterfaceGUID = {0A5FD377-0EF8-4380-AD47-F0B86D4796E0} in xml file where it says
<DriverInterfaceGUID>{0A5FD377-0EF8-4380-AD47-F0B86D4796E0}</DriverInterfaceGUID>.

Make all Auto or Hidden options set to Visible. And you are good to go.


Gosh U16 sounds fab with 8 samples (44.1/48k fs) latency on jRiver!

Is there anyway you could make the modifications to these files and upload a zip file for us to download? I just want to be sure everything is set properly.

Yes I think many of us specially with distortion problems would be very much interested if that was possible. What was the original asio buffer size and what is the maximum value?

Soumya, Thank your very much!!!

Soumya's files work for me! Thanks again. I am experimenting with U16 with this new control/interface....

Every time I change buffer size it goes back to 2048 samples. Do I need reboot or something else?

Happy to help! Glad things work for you as I intended. Enjoy!

Depends on your player. Are you using HqPlayer or have Hardware buffer enabled in ASIO setting of Jriver, If so either disable it or set it to default (for HQPlayer).
In other words don't let the application control the hardware buffer.

 

[wwmhf]

where did you change the buffer size?

Great suggestion as make sense. I disabled Hardware buffer in JRiver and now I can choose buffer size as I want. Thanks!

To be clear, here is my setup:

Windows 10 + foobar2000 -> USB to U16/1.4 firmware -> I2S to Gustard X20

In foobar2000, I am using foo_dsd_asio to upsample my CD wav files to DSD128 or DSD256, or DS512. The Buffer length in foobar2000 is now set to 20020 ms, but, in this Gustard U-16 Interface Soumya brought to us, I set the Buffer Settings to the largest possible value + checking Safe Mode

Now, I have played upsampling to DSD512 for a few songs, so far no issues. I could not do this before without hearing noise or minor pops

 

[rafabro]

where did you change the buffer size?

Those files contains small app - a control panel from previous page

 

[wwmhf]

Using the largest possible buffer value in this Gustard U-16 Interface Soumya brought to us, the following set also seems to work fine now:

Windows 10 + foobar2000 -> USB to U16/1.61 firmware -> I2S to Gustard X20

Upsampling CD wav files to DSD512 seems to work fine

Thank you Soumya.
Unfortunately it did not solve my issue with Icron 2224.

What is really weird is if I plug an wireless reciever for an logitech k400 into the icron the distortions gets much lesser, do anyone got any idea about that? Maybe something with frequency, clocks? Frustrating no sample rate works for me.
