^CINF:signalQuit received signal to quit
INF:main returning from longjump after signal [2]

(14-Sep 23:34) INF:main pid=7560 received exit signal (Hopefully crtl-C or --kill-previous !!!)

I also attached a screenhot of the mixer view.

I also have to say qasmixer doesn't show me mixer's capabilities

I'd really appreciate informations or workaround to help me to debug this :)

Sorry for the delay, unfortunately I do not have such a board in hand and cannot reproduce your problem. Your board is visible and detected, it respond to ping but it look like value return by the Alsa driver diverge with previous version. You should send manually a alsajson CTRL_GET_ALL from a command line and check for the respond. Before doing so make sure than Focusrit alsa driver is effectively loaded.
