Comment # 4 on bug 1194977 from Quirin Blaeser

Yes, you're right. I have an additionally Repo added:
https://download.opensuse.org/repositories/home:/Sauerland/openSUSE_Leap_15.3/
and
"zypper in audacity" installed from this repo due to its higher version number.

Name        : audacity
Version     : 3.0.5
Release     : lp153.187.1
...
Vendor      : obs://build.opensuse.org/home:Sauerland
...
Distribution: home:Sauerland / openSUSE_Leap_15.3

I've changed the priority of all other repos from 99 to 80, so mistakes alike
this one should not happen again.
Maybe this setting could be the default?

I think, this case could be closed.

Thanks for your effort.
