Dear all, have anyone had experience of a 4in 4out usb audio interface, working on Linux: - with all 4 channels (I can afford some tinkering if needed) - at least in USB1 compliant mode, i.e. stereo 16-bit 48kHz) I have seen the Alesis iO4 should work, as well as (maybe) the Focusrite 6i6, and the Presonus 44vsl, but I got no consistent report on neither of these.
