OK, I've reinstalled 18.04 (with the backports).
All seems good except for one strange behavior...
I have a Zoom L-12 which is a USB 14 in/4 out, class-compliant,
mixer/recorder/audio interface. If the L-12 is on at boot, jack does
not start. I can go into Ubuntu Studio Controls and "Restart Jack",
then have Patchage "connect to Jack", and everything is normal again.
I've tested this with only USB hardware synths on: normal, MIDI doesn't
trigger this.
I've tested this with only a USB mike plugged-in (bus powered, so it's
not really "on"): normal, so it's not "all USB audio".
It's just when the L-12 is on at boot... if the L-12 is off at boot, it
can be turned on and everything is normal.
So, the obvious "answer" is "then don't boot with the L-12 on" but
that's not a satisfying answer...
What might be causing this?
Has anyone else had a device "block" jack from starting?
Is this some sort of "out of order booting" that only happens when the
L-12 is on?
Thanks for any help/suggestions...
