Bug#1000669: libgstreamer1.0-0: autoaudiosink uses wrong soundcard

[Gerard L.]

Package: libgstreamer1.0-0
Version: 1.18.5-1
Severity: important
X-Debbugs-Cc: carmen@belgacom.net

Dear Maintainer,

Since a few weeks, audio from several apps like firefox, chromium, parole or 
clementine is directed to the motherboard soundcard [Intel]
instead of the pci soundcard [Live] of my desktop computer.
As apps using directly ALSA as Audacity or MuseScore are still working fine, I 
suspect GStreamer.

The PCI soundcard is always the first one because of the line "options snd 
slots=snd_emu10k1" in the /etc/modprobe.d/alsa-base.conf file.
It is also ALSA's default soundcard because of the lines "defaults.ctl.!card 
Live" and "defaults.pcm.!card Live" in the /etc/asound.conf file
I have *no PulseAudio* installed.

If I temporarily disable onboard soundcard from bios for a test then audio go 
back to the PCI soundcard.

Test of autoaudiosink does not work as expected.
 If I test GStreamer with "gst-launch-1.0 -v audiotestsrc ! audioconvert ! 
autoaudiosink" 
 then command output shows a "GstPulseSink"... but I have no PulseAudio 
installed ?!
 Also You can see that the selected device is 
alsa_output.pci-_00_1b.0.analog-stereo which is the onboard one.
See gst-auto.log below for details.

Test of alsasink is ok.
 If I test GStreamer with "gst-launch-1.0 -v audiotestsrc ! audioconvert ! 
alsasink"
 then sound go the the PCI soundcard as expected
See gst-alsa.log below for details.

Bug#978648: spyder: Exits at startup with an import error for module zmq.backend.cython

[Gerard L.]

Package: spyder
Version: 3.3.6+dfsg1-5
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: carmen@belgacom.net

Dear Maintainer,

Since the last update of my Debian Testing distro, Spyder no more starts.
When launching spyder from command line we can see a import error message
from the python interpreter complaining that it cannot import name 'constants' 
from partially initialized module 'zmq.backend.cython'. And that's most likely 
due to a circular import
 (/usr/lib/python3/dist-packages/zmq/backend/cython/__init__.py)

See attached traceback.

Thanks.
