[ubuntu_studio] Rode AI-1 interface and Jack

 
Hi!
I have a question regarding the Rode AI-1 audio interface and if anyone has managed to get the headphone output working in Jack (i.e., https://jackaudio.org/)? My goal is to record some music with Ardour in Ubuntu Studio 20.04 and for that I understand that I am better off with Jack up and running. When I connect AI-1 to the computer via a USB port, the QjackCtl gives me the option (under the “Settings..”) to use the “hw:AI1” audio interface, which seems to be just what I want. But after selecting that interface and starting Jack via the GUI I get the following output:

Sun Oct 18 19:16:15 2020: Starting jack server…

Sun Oct 18 19:16:15 2020: JACK server starting in realtime mode with priority 10

Sun Oct 18 19:16:15 2020: self-connect-mode is “Don’t restrict self connect requests”

JackShmReadWritePtr::~JackShmReadWritePtr – Init not done for -1, skipping unlock

JackShmReadWritePtr::~JackShmReadWritePtr – Init not done for -1, skipping unlock

Now, if I switch to the “advanced” tab and select the AI-1 as “Input Device”, I can actually use the audio interface to record audio in Ardour. But it seems impossible to get the same interface working as “Output device”, i.e., to use the headphone jack as sound output. If I try that, I get a simlar error as above when starting Jack. Any ideas or clues would be super helpful.

Best wishes,
Martin Moberg
