It seems it's now failing to open the configured ALSA PCM devices (which
probably also shouldn't happen?). From the strace output, it seems the
configured ALSA devices doesn't exist in /dev/snd:

That seems like a completely different failure mode.

Please note that I know very little about JACK and how it's meant to work, so I'm just working from knowledge of libraries in general. Attempting to reproduce this: - Have a Debian 10 VM. I used a minimal autopkgtest VM and installed jackd and a basic GUI, with: - apt install openbox xdm xorg xterm jackd2 - reboot - Log in, open an xterm, and run jackd -d alsa - If you have PulseAudio, prefix with "pasuspender --" (my test VM is sufficiently minimal to not have PulseAudio) - Add a bullseye apt source - sudo apt update - sudo apt install jackd2 - jackd -d alsa - Add a sid apt source - sudo apt update - sudo apt install jackd2 (this upgrades libc6, among others) - jackd -d alsa - sudo apt dist-upgrade (this upgrades remaining packages to sid versions) - jackd -d alsa In each case jackd2 appeared to start successfully for me, and its output said that it was creating an ALSA driver "hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit" or similar. I didn't (know how to) test that it can actually play back audio. To the bug reporter: some other commands whose output might be useful, replacing "jackd -d alsa" with however you normally run jackd, are: find /usr/local -name '*jack*' dpkg-query -W | grep jack env LD_DEBUG=files jackd -d alsa env LD_DEBUG=libs jackd -d alsa ldd -r /usr/lib/x86_64-linux-gnu/libjackserver.so.0 strace -efile jackd -d alsa debsums -s jackd2 debsums -s libjack-jackd2-0 (the last few require the strace and debsums packages installed). To the maintainers: It looks as though /usr/lib/x86_64-linux-gnu/jack/jack_alsa.so has undefined symbols, including _ZN4Jack17JackServerGlobals26on_device_reservation_loopE, that are not provided by any of its dependencies. The symbol _ZN4Jack17JackServerGlobals26on_device_reservation_loopE appears to be part of /usr/lib/x86_64-linux-gnu/libjackserver.so.0, which is a dependency of /usr/bin/jackd; so when jackd dlopens jack_alsa.so, the undefined symbol should be satisfied by the previously-loaded libjackserver.so.0 as per this sentence from dlopen(3): Symbol references in the shared object are resolved using (in order): symbols in the link map of objects loaded for the main program and its dependencies; [and some other places that don't matter] Does that all look like the way it is meant to work? This would probably be more robust if jack_alsa.so was linked with -ljackserver so that it was self-contained. Ideally, it would be possible to link it with the linker option -Wl,-z,defs to assert that all undefined symbols are present in its dependencies. I can reproduce lots of undefined symbols in /usr/lib/x86_64-linux-gnu/jack/jack_alsa.so on a clean installation in a VM (as above) by running "ldd -r /usr/lib/x86_64-linux-gnu/jack/jack_alsa.so". The output I see is similar to what the bug reporter sent. However, if I use LD_PRELOAD=libjackserver.so.0, the undefined symbols go away, suggesting that linking with -ljackserver would be sufficient to make the plugin fully self-contained. If JACK is portable to Windows, any plugins in the Windows build will likely already have to be linked to -ljackserver, because Windows shared libraries work differently - and indeed looking at the wscript, it seems like driver modules are linked with "serverlib" on Windows and macOS, so it would probably be a straightforward change to do the same on all platforms.
