Summary0007236: Ardour was working fine, now can't load sessions
DescriptionI had Ardour5 working fine, and spent several happy hours creating a song. Then one day I went to start Ardour, and it crashed on opening the session. What's more, it can't open any other sessions, or create new ones.

Maybe something happened during a system update? I have no idea. I've tried starting Ardour with plugins disabled, but the problem remains. I've spent several hours searching online for a solution, to no avail :-(
Steps To Reproduce1. Start jackd, either from terminal or qjackctl
2. Attempt to start Ardour
3. Weep with frustration as it fails
Additional InformationThe attached file shows the Ardour output from running from a terminal.

The following are

1. the output from ulimit
2. /etc/security/limits.d/95-jack.conf
3. the id command, showing my group membership.

The directives in the limit configuration file do not appear to be working! But, as I said above, Ardour was working fine (presumably under these conditions?), until one day it doesn't!

ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 63593

Update: when starting jackd in non-realtime mode, ardour crashes with this:


/usr/lib64/ardour5/ardour-5.5.0: symbol lookup error: /usr/lib64/ardour5/vamp/libardourvampplugins.so: undefined symbol: kiss_fftr_alloc

The ulimit problem appears to be a known bug in Fedora 25. However running >su - $USER means that the limits are applied correctly in the resulting shell, and jackd can start with realtime privileges. Also, Ardour no longer complains about being unable to lock memory, but has the following result (still unable to load or create sessions):

To verify that this is not just an issue with the Fedora build of Ardour, can you please download the latest version (There is a demo) from ardour.org and let us know if you experience the same issue. Thanks.

When used with JACK, Ardour requires realtime permissions. However on recent Fedora there's:

https://bugzilla.redhat.com/show_bug.cgi?id=1364332
http://forums.fedoraforum.org/showthread.php?t=288601


As for the missing symbol, that sounds like a build/packaging mistake of your distro (Fedora does not use Ardour's internal libs)

I suggest to use a https://nightly.ardour.org/ build with Ardour's ALSA backend (no JACK) and file a bug report with Fedora.
