No way. I do not want to install a new OS anytime soon. This LM 17
works fine
Well, apparently not, if jackd still has this ancient freewheeling bug.
Who knows what other sleeping dragons are out there.
But you're right, switching distros is a rather drastic measure.
Since Mint is Ubuntu based,

might be able to help out in your case.

no

recently.)
No drawbacks. Except you'll have to stop
jackd if you want to use the
same device as jackd is using.
There's also a "None (Dummy)" audio
system which does not need an
actual device, but this only available if Ardour was configured
with
./waf configure --with-backends=jack,alsa,dummy
(Ardour4 debug builds from
http://nightly.ardour.org/ have this
enabled).
Thanks for the details. Can this dummy option be used for exports and
will it be in the next Ardour release ?
Yes, it can be used for export. It does implement the same mechanism as
JACK freewheeling.
Its purpose is testing and debugging (and working around odd issue) and
it is not intended to be released with non-debug versions. Sorry, it
won't be part of official release binaries.
Cheers!

PS. to get back on topic,
http://www.jackaudio.org/files/docs/html/group__ServerControl.html#gad65c74…
says "faster than realtime" execution of a JACK graph
it can also be "slower than realtime", e.g live encode the jack-graph to
.ogg and/or mp3 or multiple formats at the same time which can take
considerable CPU.
