To date, I have not been able to have Ardour successfully start JACK. Which has not been an issue because I simply use qjackctl start JACK prior to launching Ardour. I use an Echo Audiofire 8, a firewire device, running with FFADO.
I finally decided to look more closely at why this may be the case. I started Ardour (2.8.14 ardour.org build) from the console without a running JACK instance. I selected FFADO from the start menu JACK options and attempted to start JACK.
As I watched the console output, I realized that Ardour attempts to start JACK with the driver incorrectly specified in the JACK command line. So, instead of
jackd -d firewire
Ardour attempts to start JACK with
jackd -d ffado
which fails. Mixbus 2.2.0 also fails in a similar fashion, using “-d freebob” when FFADO is specified.
Can this be corrected (eg some setting) without a recompile of Ardour?
For reference, I include the console output below:
Ardour 2.8.14
