Bug#916179: roger-router: selecting Preferences makes the program hang
Hello Marc Lehmann,
are you able to reproduce this hang on a installation
with just stretch package versions, too.
(Or maybe on a buster installation)
I ask because at least following packages are more current as
the plain stretch versions:
| versions reported | currently in stretch
libatk1.0-0 | 2.30.0-1 | 2.22.0-1
libc6 | 2.27-8 | 2.24-11+deb9u3
libcairo-gobject2 | 1.16.0-1 | 1.14.8-1
libcairo2 | 1.16.0-1 | 1.14.8-1
libglib2.0-0 | 2.58.1-2 | 2.50.3-2
libgtk-3-0 | 3.24.1-2 | 3.22.11-1
libjson-glib-1.0-0 | 1.4.4-1 | 1.2.6-1
libpango-1.0-0 | 1.42.4-4 | 1.40.5-1
libpangocairo-1.0-0 | 1.42.4-4 | 1.40.5-1
libsoup2.4-1 | 2.64.2-1 | 2.56.0-2+deb9u2
Even when upgrading these packages inside my test VM
I could not reproduce this hang, therefore if it is not
related to the package versions it may be related to your
sound equipment ...
----
... after some more trying I found that I could reproduce a quite
matching hang when I use following sequence (with just stretch packages):
export PULSE_BINARY=/not-existing
pulseaudio -k
roger
That effectively avoids the start of the pulseaudio daemon.
(except when some other application would restart it.)
Therefore another thing to check would be if there is really an
pulseaudio daemon running on your system? Do you start roger with some
other environments that prevent the connection to the daemon?
Kind regards,
Bernhard
