Hi Dave,

I added your repo and went ahead and updated the following packages to your
version:

- jack
- libjack0
- libjack0-32bit
- libjacknet0
- libjackserver0
- mpg123-jack
- pulseaudio-module-jack
- qjackctl
- qjackqtl-lang
- hydrogen
- libhydrogen-core1

I'm not seeing a change in behavior. One note is that I normally have qjackctl
use the DBus interface which will then load/unload the pulseaudio sinks as
needed. However, I found that when the pulseaudio sinks are loaded it blows my
entire audio system out of the water (no cards found until reboot). So I tried
to comment out the lines in /etc/pulse/default.pa that load the sinks. This
keeps my audio from blowing up, but all jack clients still segfault.

It doesn't seem to matter if using jackd or through jackdbus, the server will
start, but as soon as it any client connects (qjackctl, a2jmidid, hydrogen) the
client segfaults. The server reports a broken pipe, but keeps running.

Thinking it might be linkage to alsa or pulseaudio, I removed
~/.config/rncbc.org/QjackCtl.org and tried new config using other audio
drivers. Even with the "dummy" driver, as soon as I start jackd/jackdbus from
qjackctl, qjackctl segfaults. The server does continue to run as a daemon, but
any connecting client also segfaults.

FWIW, I use the computer for multiple things, but one is creating music with
jack and Ardour. I know that Tumbleweed is probably not the stablest audio
distribution, but I've had good luck (and stability) with this setup for many
years and my hardware configuration hasn't changed. I don't know if this is
somehow related to the recent LTO build changes (don't know if any of these
packages have it enabled/disabled).

Also, I didn't understand Konstantin's comment:

temporary switched jack and jacklib0 to 1.9.12~git20190619T124043-159 from
home:X0F

Did that mean that fixed the issue for him? I went to
https://build.opensuse.org/project/show/home:X0F, but don't even see those
packages listed, but I may be missing something.

Anyway, thanks for helping me with this.

Carl
