@LePousson - Try selecting either (both) WASAPI / Kernal Stream modes on the controls page and see if your device shows up when you click the “Output Device” selection. See my example below. If that doesn’t show it, then you might need a WASAPI driver for your interface for Audirvana to see it, but I’ll let other more experienced users chime in on that one.
The sound volume was on my side, the headphones button was set to low volume looool
But the little app to manage the USB Box does not recognize any ASIO or WASAPI driver, including ASIO4All :’(
It is a non-branded little box I had several years ago (when I was using Win 7).
This is too bad but I’ll continue using Foobar2000, which is totally free by the way, which can use ANY type of driver and that suits my needs perfectly. I thought that at least v3.5 would be able to use “DirectSound” drivers but no, only ASIO and WASAPI :’(
