I just created a full project with a combination of 39 tracks and busses with A3, and with Jack2 everything exported just fine. I haven't been able to export anything but very small projects with mixbus and Jack2. The issue definitely seems to be related to mixbus, Jack2 and the size of the project.
Hey guys.. I recently acquired a RME Raydat interface (works like a *charm*, and I love it!), but ever since I installed it, I'm getting a random error when I try to export my tracks, and it's driving me bonkers.
Previously to installing the Raydat card, I had used ardour for approximately 10 years, and have never experienced this problem.
The problem is about 75% of the time, when exporting, the GUI will just sit there and do nothing, maintaining the "export" button depressed continually. Within QJackctl's "message" window, I see the following error:
JackEngine::XRun: client = ardour was not run: state = 2
JackFreewheelDriver::Process: Process error
00:31:20.920 XRUN callback (1).
The remaining 25% of the time it exports just fine, without issue.
Needless to say, this is extremely frustrating. Googling the problem returns nothing but the snippet of code which contains the error message itself, which can be found at the link below:
I've since found that this problem only occurs in Jack2. Jack1 exports 100% of the time just fine, but I've found that Jack2 (aside from the export problem) works much better under high stress. Most of my projects contain a high number of tracks / plugins / etc... Thus, high stress. It'd be very nice to go back to Jack2, but not being able to export pretty much kills any usefulness from it. Any ideas at all?
