Since Ardour takes the sound away from all other applications, I often have to Start and Stop the Audio/MIDI Setup so I can go back and forth between applications.
That’s fine for me but sometimes I forget to start it back and I perform an operation (e.g. delete a track) and when I do that, the interface gets locked. I can’t do anything and have to kill the app and lose my unsaved work.
This happens quite often to me so I would really like if there was a way around this.
I had a similar problem with other applications, solve using jack
Try and check if it is solved
there are applications that once stopped do not release the audio
Could it be that you’re running into a bug of 5.12 that has meanwhile been fixed?
PS. Ardour6 can also use Pulseaudio for playback, so if you’re only mixing or producing in the box without any live inputs this may be an option to share the soundcard.
