Comment # 1 on bug 1194264 from Jan Engelhardt

=== What happens if... ===

1. Going forward.

# zypper in pipewire-pulseaudio
[install 454+ packages]

2. Going backward:

# zypper in alsa-plugins-pulse
Problem: the installed patterns-microos-desktop-common-5.0-40.1.x86_64
obsoletes 'alsa-plugins-pulse < 1.3' provided by the to be installed
alsa-plugins-pulse-1.2.6-1.1.x86_64
 Solution 1: deinstallation of patterns-microos-desktop-common-5.0-40.1.x86_64
 Solution 2: do not install alsa-plugins-pulse-1.2.6-1.1.x86_64


-> Tells us that patterns-microos-desktop-common.spec has a "Obsoletes:
alsa-plugins-pulse < 1.3" line.


3. Asking for forward resolution again. This gives us now a minified view of
the exhibited problem:
