Hi, Jens   Yes, I can see all the 8 channels, and re-amp on linux and Ardour and all thanks to you   As you've mentioned  1. JACK is required since it is not plays directly using ALSA and PulseAudio, However, Jack sink works greate.  2. It will be required to recopy snd_usb_audio on every kernel update.   But it is huge benefit being able to Re-Amp and  not to require all of those XLR cables   Thanks Shemeshg
