Sorry, didn't mean to imply UBS controls wasn't displaying anything. I meant that when I click stop, start, etc. no errors are shown in system log. And JACK does not start.
QJackctl can't start JACK either. It pops a error dialog saying Jack server won't start. And, as noted the onboard devices show up as selections in UBS controls, but don't get any audio.
