Solved
I’ve contacted the Audinate Support and they told me that they are aware of some issues with the latest version of DVS that sound similar, and they are currently investigating.
They suggested me to try the previous DVS version of this machine.
I’ve downloaded v 4.0.4 from https://audinate.com/content/dante-virtual-soundcard-v4043-macos
It works perfectly for me.
I’d like to thanks all you guys for all of your supportive replies, it is encouraging.
