Actually, It came with an adapter, but I don't have it with me (and the current C-plague restrictions don't make it easier). But I don't need it to follow your suggestions, because the only 3.5mm jack is the one of the MB, which doesn't matter. > > I'll explain the headphone monitor function in a moment.

One word: AHA! (It makes a lot of difference, knowing what one is doing!) This is the explanation the interface should come with, or at least they should have a site with a simple diagram. Yes, I can hear sound with the headphones connected to the headphone out in the interface, as well as with the headphones connected to the RCA output, via an amplifier. (I modified .asoundrc to make the USB card the default; not a permanent solution but manageable) I had understood the purpose of the direct monitor, but I thought wrongly that the headphone output had no other purpose by itself. OK, I tried both discord and slack with this setup. I can't hear the other side. The other side can hear me on slack, not on discord. Thanks Jorge
