Bug#994203: fails to start with silent_jack_error_callback

[Antoine Beaupre <anarcat@debian.org>]

Package: jackd
Version: 5+nmu1
Severity: grave

I have tried to use jackd in bullseye (because pipewire was giving me
problems in ardour) and it seems I can't start it at all:

anarcat@curie:~(main)$ jackd
jackd: symbol lookup error: jackd: undefined symbol: silent_jack_error_callback

I also tried to start it with the explicit "alsa" or "dummy" backends,
no luck. qjackctl also fails to start jack, which it tries to run
with;

    /usr/bin/jackd -dalsa -dhw:0 -r48000 -p1024 -n2

It fails with the same error.
