| Summary | 0007236: Ardour was working fine, now can't load sessions | ||||
| Description | I 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 Reproduce | 1. Start jackd, either from terminal or qjackctl 2. Attempt to start Ardour 3. Weep with frustration as it fails | ||||
| Additional Information | The 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 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 63593 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited > cat /etc/security/limits.d/95-jack.conf # Default limits for users of jack-audio-connection-kit @jackuser hard rtprio 90 @jackuser hard memlock unlimited @pulse-rt - rtprio 20 @pulse-rt - nice -20 > id uid=1001(john) gid=1001(john) groups=1001(john),10(wheel),63(audio),970(wireshark),975(vboxusers),978(jackuser),984(pulse-rt),1002(ipfs),1003(developers),1004(plugdev),1005(realtime) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 | ||||

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): ardour5 bind txt domain [gtk2_ardour5] to /usr/share/ardour5/locale Ardour5.5.0 (built using 5.5 and GCC version 6.2.1 20160916 (Red Hat 6.2.1-2)) ardour: [INFO]: Your system is configured to limit Ardour to only 4,096 open files ardour: [INFO]: Loading system configuration file /etc/ardour5/system_config ardour: [INFO]: Loading user configuration file /home/john/.config/ardour5/config ardour: [INFO]: CPU vendor: GenuineIntel ardour: [INFO]: AVX-capable processor ardour: [INFO]: CPU brand: Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz ardour: [INFO]: Using SSE optimized routines Cannot xinstall SIGPIPE error handler ardour: [INFO]: Loading default ui configuration file /etc/ardour5/default_ui_config ardour: [INFO]: Loading user ui configuration file /home/john/.config/ardour5/ui_config ardour: [INFO]: Loading color file /usr/share/ardour5/themes/dark-ardour.colors ardour: [INFO]: Loading ui configuration file /etc/ardour5/clearlooks.rc ardour: [INFO]: Loading ui configuration file /etc/ardour5/clearlooks.rc Found nothing along /home/john/.config/ardour5/templates:/usr/share/ardour5/templates run dialog protocol Wiimote active ? 0 protocol PreSonus FaderPort active ? 0 protocol Generic MIDI active ? 0 protocol Open Sound Control (OSC) active ? 0 protocol Mackie active ? 0 Scanning folders for bundled LV2s: /usr/lib64/ardour5/LV2 KP is ardour.keys Set cursor set to default Set buffering params to 262144|131072|10|10 /usr/lib64/ardour5/ardour-5.5.0: symbol lookup error: /usr/lib64/ardour5/vamp/libardourvampplugins.so: undefined symbol: kiss_fftr_alloc Cannot read socket fd = 11 err = Connection reset by peer Could not read notification result ClientNotify fails name = ardour notification = 18 val1 = 0 val2 = 0 Cannot write socket fd = 11 err = Broken pipe CheckRes error Could not write notification ClientNotify fails name = ardour notification = 18 val1 = 1 val2 = 0 Cannot write socket fd = 11 err = Broken pipe CheckRes error Could not write notification ClientNotify fails name = ardour notification = 4 val1 = 0 val2 = 0 Cannot write socket fd = 11 err = Broken pipe |

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. |
