Unknown driver "freebob"

I’m starting to work with Ardour.
When I run Ardour I get some errors (not detailed). But if I run Ardour through the Terminal I get: Unknown driver “freebob”. I’ve selected FFADO in driver.
If I run Jack before, no problem.

Ardour’s issue or my installation’s issue?

Thank you.

@esevece: this has already been fixed in later versions of Ardour. What version are you running?
