This is probably something stupid, but I have the following situation:
First, as you will be able to tell, I am new to Linux. I am a recovering Pro Tools Mac and Windows person…
I have installed Ardour on an Intel Duo Core Mac Mini (as a low cost test system) running a clean install of Jaunty. When I launch Ardour from the icon (and have NOT launched Jack CTL beforehand) Ardour launches fine, runs fine, and plays through the built-in sound card on the mobo of the Mac Mini. However …
I have been attempting to use my Zoom H4n as a “sound card” so I wanted to route the audio out through the Zoom H4 (which connects via USB). When I set the options from Jack Control, then launch Ardour, I get the error message "Cannot use real time scheduling (Fifo …) etc. which I understand is a kind of “permissions” issue with users and the root. OK, understand that.
So, I ran qjackctl from the terminal with a SUDO to launch from the root. Then I changed the interface in the Jack Control to the H4 usb device, saved, quit, launched qjackctl again from the terminal, then launched Ardour from the terminal as well.
This generates the error message: Alsa: could not start playback (broken pipe).
When I follow this same procedure but choose the Intel Audio instead of the H4, I get a message that Jack is already running.
Again, the simple launch from Jaunty’s menu works, so I am going to experiment with Ardour running through the built-in audio. But I would like to use Jack Control.
Can anyone help me trouble shoot this? I have found others with the same issue, have read through many posts, but nothing that seems to really cover this situation. Thank you for any help.
