MarsSeed [1] filed a deletion request for lib32-jack [2]: Unneeded broken orphan lib32 jack1 library. Missing some dependencies as least since 2022-10 (as per last comment). Repo carries lib32-jack2, which provides 'lib32-jack'; also lib32-pipewire-jack provides the same interface. Safe to delete this defunct package.
