Ardour6 gives the error “Failed to op audio device” where I did not find a solution for in this forum. I am on Windows. I payed for the current version and future updates (Ardour5 gives the same error). I tried every possible option in the menu.
(edit: Now that it works, I wanted to say that Ardour6 has improved very nicely compared to Ardour5. Ardour6 looks and controls way smoother. Great job!)
Worked! Thanks! Windows can be such a rabbit hole. This is why I only use tools that also have Linux support, so I can switch to Ubuntu in the near future.
