x42 2024-09-28 14:33 administrator ~0028994	Thank you for this report. Are you using pipewire or jack? and which version. The crash here happens when Ardour asks jackd (or pipewire) about port meta-data.

red75 2024-09-28 14:43 reporter ~0028995	Hello, Q: Are you using pipewire or jack? and which version. A: I am using jack offered by Fedora from repository jack-audio-connection-kit-1.9.22-5.fc40.x86_64 qjackctl-1.0.1-1.fc40.x86_64 The crash here happens when Ardour asks jackd (or pipewire) about port meta-data. My question: When possible, is there an option in qjacktl to ensure Ardour receive proper meta-data of jackd?

red75 2024-09-28 14:46 reporter ~0028996	Additionally I did test to start Ardour without jack, then I was asked to choice for ALSA/JACK/..., when I choice ALSA then Ardour starts without crash.

red75 2024-09-28 14:48 reporter ~0028997	Confirmed, when I start to using Jack, then it crash during start after I choice to connect to jackd.

paul 2024-09-28 14:54 administrator ~0028998	This crash is caused by JACK. Which implementation of JACK are you using?

red75 2024-09-28 15:00 reporter ~0028999	Hello Paul, I am using distribution packages from Fedora 40, the jackd I am starting by qjacktl. Versions you can see in my previous reply 0009803:0028995.

paul 2024-09-28 15:16 administrator ~0029000	Well, I have never used JACK2, but certainly JACK1 has long (decades?) had issues with the metadata API. Restarting JACK would fix this. I started using pipewire last month, and have not seen this issue there, but I could go months between it occuring with JACK1 so that doesn't prove much.

x42 2024-09-28 15:27 administrator ~0029001 Last edited: 2024-09-28 15:28	Looking at Fedora's build log (https://kojipkgs.fedoraproject.org//packages/ardour8/8.7.0/1.fc42/data/logs/i686/build.log) * Libjack linking : link * Libjack metadata : True The official build (which crashes) dynamically loads `libjack.so.0` instead. Could it be that you have some lingering libjack.so.0 around in the ld.so library path? The odd part is that there is no library mentioned for the call, and yet there is debug information with line number [1] #0 0x00007ffff5abc289 in Jack::JackMetadata::GetProperty (this=0x5555575e4840, subject=4294967300, key=0x7fff7c065ac0 "http://jackaudio.org/metadata/pretty-name", value=0x7ffff511cb80, type=0x7ffff511cb88) at ../common/JackMetadata.cpp:319 0000001 0x00007fffa8427d6b in ARDOUR::JACKAudioBackend::get_port_property(std::shared_ptr<ARDOUR::ProtoPort> const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) const () from /opt/Ardour-8.7.0/lib/backends/libjack_audiobackend.so Surely Fedora does not ship a non-stripoped libjack with detailed debug information.

Over here I am only missing possibility to start or stop a script automatically for enable or disable 'a2jmidid' as I am using USB MIDI keyboard (KEYSTATION 49MK3). The 'a2jmidid' ensure keyboard are connected to 'jackd' and offer for other applications to use it. In 'qjacktl' I have option in Scripts for starting and stopping this automatically.

red75 2024-10-02 19:30 reporter ~0029009	Guys, I think current issue can be closed as Ardour triggers 'jackd' itself properly without crashing. Problem is only to connect to the externaly running 'jackd' triggered by 'qjacktl'. This is not probably issue on Ardour itself (my opinion). Thank you for your support.

x42 2024-10-02 22:24 administrator ~0029010	> Problem is only to connect to the externaly running 'jackd' triggered by 'qjacktl'. This is supposed to work as well, and does here in a quick test. Also I know others use Ardour in that way. Then again it seems there is something specific to your system that causes the issue here, and maybe other Fedora users are also affected.

ccaudle 2024-10-04 20:40 reporter ~0029012	I think I also hit this recently, but did not have time to investigate when it occurred. Seeing a copy of libjack.so in the carla directory seems strange, I do not know why that is there. It should not be in the search path, and I do not use Carla, so I don't think it was related. I have removed Carla from my machine, so I will test again to verify. This machine is an x64 installation, but there is an i686 build of jackd in the Steam directory. I expect that is for Steam apps only, but like Carla I had no Steam apps running when the crash occurred, so I don't suspect that is relevant. I checked .config/rncbc.org/QjackCtl.conf and did not see any explicit path to jackd, but the conf file did reference .jackdrc which explicitly indicates /usr/bin/jackd, so I do not suspect that the jackd from Steam or Carla is being started. Is this lack of output from ldd because of "weak linking" libjack to ardour? I do not know the details of how that works, but I thought that ldd would show ardour relying on libjack.so. $ ldd /opt/Ardour-8.7.0/bin/ardour-8.7.0 \| grep -i jack $ $ ldd /opt/Ardour-8.7.0/lib/backends/libjack_audiobackend.so \| grep jack $ I have a RedHat bugzilla account, so if this looks like an upstream problem I can submit a ticket to have the packager check. Seems likely to be an interaction issue between jackd and Ardour if older Ardour versions didn't crash, though. Is Ardour doing something new with the metadata API recently?

ccaudle 2024-10-05 01:54 reporter ~0029013	Confirmed that with Carla removed (so no separate copy of jackd in the carla directory) Ardour 8.8 still segfaults. I have not had to rebuild any rpms lately, but I think I still should have most of what is needed to rebuild RPMs from source, so if there are any ideas of a potential incorrect build setting I can try rebuilding and testing. I did confirm that Ardour 7.5 also gets a segfault, so this seems to be something new with the Fedora jackd. I have not needed jack lately, so have not used it in a few months, since before the upgrade to 1.9.22. I think the previous version was 1.9.20, but I am not completely positive. I also tried Ardour 6.9, but it had a different BadWindow (invalid Window parameter) error. I am currently running XWayland and always before (when 6.9 was current) I ran a true X session, so I am not planning on investigating the 6.9 problem any further. But definitely the 7.5 error looks like the same symptom.

paul 2024-10-05 02:22 administrator ~0029014	There have been no changes to the JACK backend of any significance for several versions.
