Weird problem with Motu M4 no output

Agreed - who knows - I’ll keep my eye on it- did yours mute too?

I have not seen the muted condition yet. I haven’t seen the same problem I experienced on my production rig since I returned home from the show, but that is usually off unless I’m rehearsing with it.

Update: I left my main rig on overnight and still don’t see the issue - everything still plays/sounds fine. In the meantime I located a used RME fireface UCX II device on musician’s friend at a decent price (40% less than retail) and ordered that last night, will start using it with my dev machine at first.
