Ardour "Failed to open audio device) which is Scarlett 4i4 4th Gen

I have Geoffrey Bennett’s GUI installed, and a lesson from Geoffrey on CONNECTIONS for his GUI. I’ll watch the Skype recording and see if I can work on this.

Card 2 (Gen):

That is how ALSA displays the short name for a Scarlett 4i4?

There is no software using that USB device (closed for both playback and recording), so no obvious reason why Ardour would fail.

Is there any information about device failure in the Ardour log window?

[SOLVED] Thank you though to ccaudle

Ardour now sees the 4i4, and I’m working on routing. Not an easy thing though.The solution was messy?;
