QjackCtl icon is an Exclamation Mark - No idea why


I am trying to set Jack up on my Mint desktop. Haven't managed to get it to work yet.

I reset settings to default and now I have the qJackCtl exclamation mark on my iconbar. The context-sensitive tool-tip just says 'JACK Audio Connection Kit [(default)] Active. (0.64%, 0 xruns)', there's absolutely no hint as to WHY it is in an erroneous state.

I tried searching but there seems to be a new company called "Jack'd", which Google now thinks I am talking about even though I didn't type an apostrophe pmsl Google always 'knows better', eh? ffs

Anyone know why the icon is an exclamation mark? Also, just for some insight into modern software development issues, are my expectations of some visible error information from the software too difficult a concept to accept nowadays?

Also, is there any up-to-date, accurate documentation for a Jack-based set-up with Ardour on Mint or, again, are we expected to guess correctly, nowadays?

Many thanks for any information.

first it is NOT in an erroneous state whatsoever: qjackctl is active and running in pure client mode, probably due a genuine-jackd service is already up and running OR it's running under the pipewire-jack substitution environment--both cases are perfectly normal situations.

second, the exclamation mark icon is a temporary notification icon telling you the application is being minimized to the system-tray icon and it should persist for a brief period of time only (usually 6 seconds or so...) -- if you don't want this or you're using a desktop environment that does not support the system-tray or notification area icons you may well disable the said feature (uncheck Setup > Misc > Enable system tray icon).
